Lockerbie conspiracies: from A to Z

[What follows is the text of an article published in The Guardian on this date in 1999. Some of the "conspiracies" have since been comprehensively debunked. Others have not:]

Lockerbie conspiracies: from A to Z

A

is for Africa, South

Several pieces of evidence (see H and W) suggest that the authorities knew in advance that the Boeing 747 which blew up over Lockerbie in southern Scotland on December 21 1988 was in danger. The German newspaper Die Zeit claimed that the South African foreign minister, Pik Botha, intended to fly on Pan Am 103 but had been warned off. Mr Botha flew on an earlier flight, Pan Am 101, which, unlike flight 103, had special security checks at Heathrow. No one has been able to definitively confirm or refute the Die Zeit story.

B

is for bomb-maker

The German anti-terror campaign Operation Autumn Leaves (see J, O and P) led to the arrest of bomb-maker Marwan Khreesat weeks before the Lockerbie disaster. Khreesat was released after a few days because of a lack of evidence. In April 1989 further German police raids resulted in the discovery of two more bombs designed by Khreesat specifically to blow up aircraft. Did he make the bomb which was placed on feeder flight Pan Am 103A before it left Frankfurt for Heathrow?

C

is for coffin

Two coach-loads of officials arrived at the disaster scene in the day after the crash. Many were plain-clothed Americans with no obvious affiliation. Among their baggage was a single coffin for which no explanation has ever been given. Labour MP Tam Dalyell later produced evidence indicating that the Americans had "stolen" a body from the wreckage. A local doctor identified and labelled 59 bodies and was then puzzled to find that the Americans had relabelled and tagged only 58 in the area where he had been working.

D

is for drugs

Lockerbie farmer Jim Wilson found a suitcase full of cellophane packets containing white powder among the debris in his fields. The suitcase was taken away, no explanation was given, and the authorities continued to insist that no drugs (apart from a small quantity of cannabis) had been found on the plane. But it was later discovered that the name Mr Wilson saw on the suitcase did not correspond with any of the names on the Pan Am 103 passenger list.

E

is for the Express

Ten days after the Lockerbie disaster, the Daily Express devoted its front page to exposing a Lebanese American called Khaled Jafaar whom it named as the "bomb carrier". The Express's sources were "the FBI and Scotland Yard". The Interfor report (see I) also named Khaled Jafaar as the bomb carrier.

F

is for fiction

It has been argued that talk of the CIA, cover-ups, bombs, timers and Maltese trousers (see M) is just entertaining fiction. Some observers believe that there was no bomb on Pan Am 103 and that explosive decompression or an electrical fault caused the Lockerbie disaster, as they caused other Boeing 747 crashes.

G

is for Garrick

Paul Channon, British Secretary of State for Transport, lunched five journalists at the Garrick Club three months after Lockerbie and told them, off-the-record, that the Lockerbie killers had been identified and would soon be arrested. Yet the two Libyans who came to be the prime suspects were not charged until November 1991. It seems likely that at that time Mr Channon was confident that the Lockerbie bomb was the work of the Palestinians (see P).

H

is for Helsinki

Sixteen days before the disaster, a man rang the US embassy in Helsinki, Finland, and warned of a bomb aboard a Pan Am aircraft flying from Frankfurt to the US. The 1990 US President's Commission report on aviation security said that "thousands of US government employees saw the Helsinki threat". Not a single US worker at the Moscow embassy took flight Pan Am 103 from Frankfurt, a standard and popular route home for Christmas. But the British Department of Transport had told Pan Am in December that British intelligence dismissed the threat as "not real".

I

is for Interfor

A report by Interfor, a New York corporate investigative company hired by Pan Am, suggested that a Palestinian gang (see P) had got the bomb on to the airliner at Frankfurt by exploiting a US intelligence deal (see U). In a bid to free American hostages in Beirut, American intelligence agents had apparently struck a deal with Syrian drug smugglers: in exchange for hostage information, the agents smoothed the Lebanon-US drugs route by relaxing security restrictions and allowing drug luggage to sail through customs. The terrorist gang simply switched the drug luggage for a bomb.

J

is for Ahmed Jibril

Ahmed Jibril was the leader of the Popular Front for the Liberation of Palestine - General Command (PFLP-GC) (see P). He enjoyed the protection of the Syrian government. Intelligence agents reported that Jibril had been assigned by a furious Iran to avenge the shooting down of an Iranian airbus by a US warship in 1988 (which killed 290 people). The leader of Jibril's terrorist gang, Hafez Dalkamoni, was one of the Palestinians arrested in Operation Autumn Leaves (see O).

K

is for Kuwait

In 1990 Kuwait was invaded by Saddam Hussein. Anglo-American attitudes to the Middle East were transformed. Paul Foot and John Ashton argue that theories about Lockerbie are inextricably linked to this changing political situation. In 1989 intelligence-based evidence fitted snugly with US and British foreign policy in the Middle East. Both countries had severed relations with Syria, and the Iraq-Iran war ended in 1988 with America and Britain continuing to be hostile to Iran and supportive of Iraq. The US and British governments were content with the prime Lockerbie suspects: a Palestinian gang (see P), backed by Syria and Iran. But in 1990, the impending Anglo-American war against Iraq necessitated neutralising Iran and winning the support of Syria. Britain's diplomatic relations with Syria were duly restored in November 1990 and the Gulf war commenced in 1991. Sure enough, the credibility of intelligence theories about the Lockerbie bombing being masterminded by the Iran- and Syria-backed Palestinian gang was soon dismantled.

L

is for Libya

In November 1991, the American and British governments charged two Libyan airline officials, Abdel Basset Ali Al-Megrahi and Lamen Khalifa Fhimah, with planting the Lockerbie bomb. To justify the radical change in the investigation's focus away from the Palestinians, the US State Department said: "Fresh evidence undermined the initial theory linking the PFLP-GC (see P) to the bomb". This included evidence that the Lockerbie bomb's "sophisticated electronic timer" had been delivered from Switzerland to Libya. And, in contrast, the bombs discovered in the hands of the Palestinians in Germany (see B) had "relatively crude timers".

M

is for the Maltese connection

A series of Sunday Times investigative pieces reported that the Lockerbie bomb had first been put on a plane in Malta. The bombing had been carried out by the Palestinian group (see P), after a gang member, Abu Talb, visited Malta. He was identified by a Maltese boutique owner as the man who bought clothes later found in the bomb suitcase. A bag which ended up on Pan Am 103 was identified by a baggage handler as coming from an Air Malta flight. When a Granada TV documentary repeated the allegations, Air Malta sued Granada for libel. A hitherto unpublished document from Air Malta's lawyers demonstrated that there were no bags on the flight which went on to Pan Am 103 or 103A. Granada settled out of court.

N

is for not proven

Legally defined as "a criminal verdict, somewhere between guilty and not guilty, the consequences of which are that the accused is treated as if found not guilty". Britain and the US fear that if attention is paid to the conflicting conspiracy theories, the case against the Libyans in The Hague could only be "not proven".

O

is for Operation Autumn Leaves

Five weeks before the Palestinian warning (see I) was received, a German anti-terrorism campaign, Operation Autumn Leaves, arrested a "team of Palestinians not associated with the PLO" in possession of a bomb in a cassette recorder (see T) strikingly similar to the Lockerbie bomb. These Palestinians, including Hafez Dalkamoni (see J) and Marwan Khreesat (see B) had been arrested outside a flat in Neuss - two hours' drive from Frankfurt, from whose airport Pan Am 103's feeder flight had originated. They were released after five days because there was not enough evidence against them.

P

is for Palestinians

Operation Autumn Leaves led to the arrest of a gang associated with a splinter group of the Palestinian movement the Popular Front for the Liberation of Palestine - General Command (PFLP-GC). Was Pan Am 103 blown up by a Palestinian gang, protected by Syria and paid for by Iran?

Q

is for Queen's English

The official air accident report concludes: "The detonation of an improvised explosive device led directly to the destruction of the aircraft". If it was a bomb why wasn't it called a bomb in plain English?

R

is for red tarpaulin

On the night of the disaster teams of rescue volunteers scouring the area discovered a large object under a red tarpaulin. As they approached it, they were warned off by gunmen in the doorway of a hovering helicopter. A local farmer, Innes Graham, was also warned by US investigators to stay away from a small wooded area a few miles east of Lockerbie.

S

is for the Swiss circuit board

A central piece of evidence which pointed to the Libyans (see L) was a tiny fragment of a circuit board found among the Lockerbie debris. This was traced to a firm in Switzerland which exported timers to Libya. Apart from the confusion over when and where the circuit board was found (reports vary between June and November 1990), the Libyan connection to the timers is not as clear-cut as investigators have claimed. The US state department maintained that all timers from the Swiss firm had been delivered to Libya, but a BBC radio programme later proved that the firm had provided identical timers to the East German secret police, the Stasi.

T

is for Toshiba

The German anti-terror campaign Operation Autumn Leaves (see O) discovered a Toshiba cassette recorder packed with semtex. Pieces of a similar model of recorder had been found in the wreckage at Lockerbie.

U

is for US intelligence

There have been several claims that the bomb was planted on Pan Am 103 by a crack team of US intelligence agents. A Radio Forth journalist reported the claim and, within an hour, was threatened with prosecution or, bizarrely, invited to disclose his source to the Prime Minister. The Interfor report (see I) also alleged that Major Charles McKee, the head of the US intelligence team, who was travelling on the plane, was shocked by his colleagues' deal with Syrian drug smugglers and was returning on Pan Am 103 to report them. The inference was obvious - Pan Am 103 was sacrificed by the intelligence community to get rid of Major McKee. But the Interfor report was greeted with widespread scepticism.

V

is for Vincent Cannistraro

In the early 1990s the Lockerbie investigation shifted from the Scottish Borders to the CIA base in America. The man in charge there was Vincent Cannistraro. Mr Cannistraro had worked with Oliver North in President Reagan's National Security Council and, Paul Foot and John Ashton argue, he "specialised in the US vendetta against Libya". Mr Cannistraro was part of a secret programme to destabilise the Libyan regime which culminated in the US bombing of Libya in 1986. He retired from the CIA in September 1990 but by then had helped lay the foundations for a completely new approach to the bombing investigation, in which the chief suspect was not Iran or Syria, but Libya.

W

is for warning

Three days before the Helsinki threat (see H), an intelligence source in the US state department's office of diplomatic security warned that a team of Palestinians, not associated with the PLO, was targeting Pan Am airline and US military bases in Europe. The comment attached to the message read: "We cannot refute or confirm this".

X

is for xenophobia

In 1989 Anglo-American intelligence services and politicians widely blamed the Lockerbie bomb on a Palestinian terror group (see P), backed by Syria and Iran. In 1990, (see K) Iraq became the Anglo-American Arab enemy number one in the run-up to the Gulf war; Iran became neutral and Syrian troops joined the Allied forces. Only Libya remained adamantly aligned with Iraq. Suddenly, coincidentally, the Lockerbie bomb was blamed on the Libyans.

Y

is for Yvonne Fletcher

PC Yvonne Fletcher was shot dead outside the Libyan embassy in London in 1984, causing diplomatic relations between Britain and Libya to be severed. The file on Yvonne Fletcher is still open and Britain continues to demand Libyan co-operation on the matter. The fairness of the trial of the two Libyan suspects could yet affect this case.

Z

is for Zeist

Camp Zeist is the former US air base in The Hague where the two Libyans are being tried under Scottish law. But even the conviction of Abdel Basset Ali Al-Megrahi and Lamen Khalifa Fhimah seems unlikely to still the disquiet and conspiracies that continue to surround flight Pan Am 103.

Dismayed by a 35-year-long miscarriage of justice

[What follows is excerpted from a report published yesterday evening on the website of The Telegraph:]

Ever since Flora was killed on Pan Am Flight 103, Dr Jim Swire has been searching for answers – and says the FBI has the wrong man

Flora Swire is everywhere in her parents’ home. There are sketches and photos of her pinned to a board in the kitchen, on the mantelpiece, on the cover of a book; her portrait fills the wall across from their bed. There remains too a lock of her hair – a heartbreaking keepsake taken when the Swires saw her last, almost 35 years ago, after a bomb exploded beneath her feet in the Lockerbie disaster.

It was on 21 December 1988, the eve of her 24th birthday, that Flora, a promising neurology student who had just been accepted to do a PhD at Cambridge, took her seat on a plane bound for New York. She had hoped to spend Christmas with her boyfriend, but would never make it.

Thirty-eight minutes after taking off at Heathrow, Pan Am Flight 103 exploded in the sky over the town of Lockerbie in Dumfries and Galloway, with such force on a windy night that the debris landed across an 845-square-mile radius from southwest Scotland to the east coast of England. The fairylights on Christmas trees all over Lockerbie blew their fuses, along with the rest of the grid; smoking orange flames illuminated the town, which quickly filled with the stench of jet fuel. (...)

The investigation has remained open ever since, with one man, Abdelbaset al-Megrahi, a Libyan national, the only person ever to be convicted of the atrocity. He was convicted in 2001 and given a life sentence, and died in 2012. But in February this year, the case returned to the courts for the first time in more than two decades.

Another Libyan national, Abu Agila Mohammad Mas’ud Kheir Al-Marimi (known as Mas’ud) has been accused of making the Lockerbie bomb, and is now awaiting trial (he has pleaded not guilty). The development should offer some shred of hope for the families whose lives irreparably changed that night. Yet Dr Jim Swire, Flora’s father, ‘has no interest’ in the prospect of Mas’ud’s conviction.

‘I know he didn’t make the bomb,’ Jim tells me. ‘I know who made the bomb.’

As such, the official criminal verdict on events to date – upcoming trial included – is, in his view at least, nothing more than ‘twaddle’.

Jim, now 87, had been writing Christmas cards on that December night in 1988 when his wife Jane told him that a plane had just come down over Scotland. He tried calling Heathrow, where Flora had been dropped off by her younger sister, Cathy, a few hours earlier – he spent five hours on hold to Pan Am as news coverage blared, showing body parts hanging from a roof, the 30ft hole a chunk of the 747 had left in a Lockerbie street, and relatives howling in anguish at JFK Airport. When he finally got through, staff confirmed the worst possible news: Flora had been on the flight. (...)

Jim, an old Etonian who went to Cambridge, is still spry in his late 80s – part-raconteur, part activist, wearing a sharp grey suit and trainers. Today, Jim, who became a GP but ultimately left the profession after his daughter’s death, and Jane, 84, take turns bustling between the kitchen and back garden of their home in the Cotswolds town of Chipping Camden with offers of cheese sandwiches and cups of tea. It is a cosy idyll that conceals the sea of names and dates and evidence-tag numbers still etched on their minds.

Some 35 years on, the Swires’ agony remains barely beneath the surface, the memories of their eldest child both a precious gift and cruel reminder of what they have lost. ‘To lose a close family member gives you a life sentence immediately,’ Jim says. ‘Your whole life is altered. And you have to start asking yourself how, how can you go on living, or how can Jane go on living, with a loss so terrible as this?’

Their experiences are documented in Lockerbie, a new four-part documentary that airs on Sky next week. It is a panoptic watch, following the lives of the residents in the town that was, until that day, just a fish ’n’ chip pitstop, 75 miles from Glasgow, before it was completely upturned. The documentary follows the families of UK and US victims, and officials from across the town’s police force, the FBI and the CIA, too. But it also lays bare how devastation led to remarkable acts of humanity, as residents mounted a volunteer effort to wash the clothes and teddies scattered thousands of miles from where they should have ended up, and sent them back to passengers’ loved ones; some of which resulted in relationships with grief-stricken families an ocean away that remain strong. Their lives are, now, forever intertwined.

But underlying the heartfelt stories is a darker thread – for decades on, opinions about who was to blame for the disaster are more divided than ever.

Jim remains dismayed by what he sees as a 35-year-long miscarriage of justice. In the immediate aftermath of the disaster, he became the spokesperson for the UK Families Flight 103 group and in the intervening decades, he has met numerous experts and officials, and had independent reviews of evidence undertaken. All of which has convinced him that justice has not been served – and that the wrong man was imprisoned, just as another ‘wrong man’ is now about to be tried.

His theory – that Libya wasn’t responsible for the bombing – runs counter to al-Megrahi’s conviction and Mas’ud’s arrest, and has been dismissed by many. But there are others in his corner, too. ‘Enough honest, reliable and knowledgeable people have discovered the awful truth behind this to know that the truth will now be able to look after itself,’ Jim says. ‘If I die tomorrow, I know the truth will eventually come out.’

Among those people is former CIA investigator John Holt, the long-time handler for the principal US government witness at al-Megrahi’s trial, Libyan agent Abdul Majid Giaka. Holt said at the time that Giaka never provided ‘any evidence pointing to Libya or any indication of knowing anything about that nation’s involvement in the two years after the bombing’ – despite later testifying. But when accused of lying under cross-examination, Giaka replied: ‘I had no interest in telling anybody any lies.’

Others who have been vocal about what they view as Libya’s wrongful implication include solicitor Clare Connelly, director of the Lockerbie Trial Briefing Unit, an independent project established by the School of Law of the University of Glasgow, and other UK relatives, including John Moseley [sic], whose 19-year-old daughter Helga was killed on Flight 103.

Al-Megrahi’s trial took place 22 years ago at Camp Zeist, a Scottish law court set up in the Netherlands (deemed a neutral territory), where judges heard that he had placed a bomb in a Samsonite suitcase. Lamen Khalifa Fhimah, his co-accused, was acquitted.

There was no smoking gun for the prosecution, but al-Megrahi was found guilty based on a series of links they felt couldn’t otherwise be explained: including that he had an office in Switzerland down the hall from a clockmaker whose device was used to make the bomb; and that clothing fragments found alongside remains of the bomb were traced back to a Maltese shop that its owner, Tony Gauci, said al-Megrahi had visited.

At the same time, there were escalating tensions between the West and Libyan premier Colonel Gaddafi, who was suspected to have ordered the bombing of a nightclub frequented by US personnel in West Berlin in 1986. Judges in al-Megrahi’s trial conceded the case included ‘a number of uncertainties and qualifications’; yet he was sentenced to life. (Libya later paid $2.7 billion to families of Lockerbie bombing victims, though this was considered a political move rather than an admission of guilt.) (...)

Time has only bolstered his defence of ‘poor’ al-Megrahi, having formed personal relationships with both him and Gaddafi before they died. They would exchange Christmas cards, and when al-Megrahi was given compassionate release in 2009 following a diagnosis of prostate cancer – returning to a hero’s welcome on the tarmac at Tripoli airport – Jim travelled to Libya to see him on his deathbed. At the time, Jim recalled al-Megrahi’s words to him: ‘I am going to a place where I hope soon to see Flora. I will tell her that her father is my friend.’

He was, in Jim’s eyes, only ever an unwitting pawn in geopolitically motivated ‘deception’ that he says is even now preventing justice for Flora and the other victims from being served. He also took a handful of clandestine trips to Gaddafi’s compound (he did not tell any authorities, and only informed Jane imminently beforehand), in which he would hear that the regime had not been to blame. On leaving their first meeting, Jim pinned a UK Families Flight 103 badge to Gaddafi’s lapel as a show of solidarity for the truth. He believes other UK families are onside, although many have never spoken publicly. But there are certainly others, particularly those in the US, who see this affinity with Gaddafi as a grave error.

For Jim, there are two pieces of evidence that point to al-Megrahi’s wrongful conviction. The 2001 case heard that the explosive had first travelled from Malta to Frankfurt, where Flight 103 began its journey to New York. (The London Heathrow stop was a layover.) But Jim believes the bomb was planted at Heathrow. At al-Megrahi’s appeal in 2002, a baggage handler told lawyers that the baggage build-up area at Terminal 3 had been broken into the night before the bombing.

The other piece of evidence relates to the bomb fragments. According to John Ashton, a researcher on al-Megrahi’s legal team, documents not disclosed during the original trial found differences between the metals of the timers being supplied to the Libyans at the time and those within the fragments police recovered from the Lockerbie site. The circuit-board patterns, however, did align, deemed to be the more important evidence.

Clare Connelly of the Lockerbie Trial Briefing Unit also questions the veracity of shopkeeper Tony Gauci’s evidence, as there have been claims that he was paid in connection with his participation in the inquiry, which she says would be ‘totally contrary to the interests of justice’. But in November 2013 the Crown Office said: ‘No witness was offered any inducement by the Crown or the Scottish police before and during the trial and there is no evidence that any other law ­enforcement agency offered such an inducement.’

As for who was actually responsible, Jim argues it was Iran, not Libya. He goes on to suggest that it might have been a retaliatory attack for the US shooting down an Iranian passenger plane, thought to have been incorrectly identified as a fighter jet in July 1988, which killed 290 innocent civilians. In his view, with American hostages held in Iran at the time and an upcoming election, the finger had to be pointed elsewhere. ‘What we’re being told is absolute nonsense from beginning to end. It was designed to protect the relationship between Britain and America and to help in getting home American hostages held by Iranian interests back in ’88.’

Jim insists that the bombmaker was not Mas’ud, as the US alleges, but ‘a Jordanian who was a double agent, or even a triple agent’ – feeding intelligence both to his own country and the CIA, while making explosives for a militant group active in Palestine at the time, called the PFLP-GC. Others have theories of their own around Iran’s involvement: Holt has also said ‘there was a concerted effort, for unexplained reasons, to switch the original investigations away from Iran and the PFLP-GC’ – backing Jim’s belief that the focus on Libya was politically motivated.

For the officials who spent years putting together their case, however, Jim’s theory is not credible enough to upend ‘the biggest case the FBI ever had… I don’t believe, in the history of law enforcement, there was a crime quite like Pan Am 103.’ So says Richard Marquise, who led the FBI investigation. ‘I will never attack [Jim], I will never tell him he’s a liar or wrong. I will never say a negative thing, because I cannot feel his pain; I am sure it’s enormous. But I disagree with his assessment of the evidence.’ (...)

For Jim, his ‘obsession’ has been an outlet for the pain of losing Flora. As he puts it: ‘It has provided me with a way of coping with my grief.’

As for Jane, she has had little choice but to accept her husband’s dogged pursuit of answers; something Jim is painfully aware of. ‘[I often think] what is it doing to Jane, that I’m still doing this?’ he admits. (...)

There is another source of anguish for the Swires – a series of missteps without which Flora may never have boarded Flight 103 in the first place.

In late October 1988, West German police found a bomb hidden inside a Toshiba radio cassette player in an apartment in Neuss, believed to have been manufactured to detonate mid-air. The British Department of Transport (DoT) went on to warn airports and airlines of its existence via telex the next month.

Then, on 5 December, an anonymous threat was phoned in to the US embassy in Helsinki, stipulating that within two weeks, someone would carry a bomb on to a Pan Am flight from Frankfurt to the US. Notices were put up on embassy walls, and US officials were told they could rebook on another flight home for Christmas if they so wished; Interpol informed 147 countries, Britain included – yet the ‘Helsinki warning’ was never made public.

Two days before Lockerbie, a circular featuring images of the explosives authorities feared had been designed to blow up planes was signed by the DoT’s principal aviation security advisor, but never sent out. (...)

Jim would like there to be an examination of the evidence in the International Criminal Court. He sees this as the only possible route to justice now – but each passing year makes it less likely.

‘Our numbers are dropping all the time from people dying off from old age,’ he says of the families’ group, ‘and I’m amazed that I haven’t long ago because the stress all this has been over the last 35 years – why I haven’t died of a heart attack, I don’t know… But I would love it if [the truth] were to come out while we were still around.’

John Dower, director of the new documentary, says that his main hope is that those involved in it will ‘get some resolution, some peace, because that’s what struck us most making this, the ongoing trauma. It’s 35 years later, but that trauma is still there.’

Lockerbie will be on Sky Documentaries and Now from 25 November

"The coverage of the film is more notable for what it omits than what it reveals"

[What follows is the text of an article by John Ashton headlined The Lockerbie Case published in today’s edition of the Scottish Review:]

Lockerbie is back in the news. On 15 October the Crown Office announced that the lord advocate and the US attorney general have agreed that two Libyan men should be treated as suspects. They have been named as Abu Agila Masud, an alleged bomb-maker whose identity was until now a mystery, and Abdullah Senussi, Colonel Gaddafi’s former security chief. Both men are currently in prison in Libya.

The announcement was prompted by the recent broadcast by the American PBS channel’s 'Frontline' series of a three-part documentary, My Brother’s Bomber, made by Ken Dornstein, who lost his brother David in the attack. Trailed by a long feature in The New Yorker, it suggests that the Libyan man convicted of the bombing, Abdelbaset al-Megrahi, was guilty and that he acted with Masud.

The film has provided the much-derided Crown case against Megrahi with the only significant boost it has had since he was convicted almost 15 years ago. That case, accepted by the three Scottish law lords who tried him, went as follows. Two weeks before the bombing, on 7 December 1988, he bought a selection of clothes from a shop in Malta called Mary’s House. On 21 December 1988, while travelling on a false passport he placed an unaccompanied brown Samsonite suitcase on board Air Malta flight KM180 from Malta to Frankfurt.

The suitcase contained the clothes and a bomb, and was labelled for New York on PA103. At Frankfurt it transferred to Pan Am feeder flight PA103A to London Heathrow, and at Heathrow to PA103. The bomb was allegedly built in to a Toshiba BomBeat brand RT-SF16 radio cassette player. A large percentage of the global total of this model had been imported by the Libyan General Electrical Company, which was run by Megrahi’s friend and relative Said Rashid, who was a senior figure in Libyan intelligence service, the JSO. More importantly, it was said to have been detonated by a timing device known as an MST-13, which had been designed and built to order for the JSO by a small Swiss company called Mebo, whose Zurich offices were shared by a Libyan company called ABH, in which Megrahi was a partner.

Before I go further, I should declare an interest. I worked for three years as a researcher for Megrahi, helping his lawyers prepare for his appeal against conviction, and following his return to Libya, at his request, I wrote his biography Megrahi: You are my Jury. I was also a paid consultant during the early stages of the film’s production in which capacity I was interviewed on camera (although the interview doesn’t appear in the film) and provided Ken with numerous documents. Although he and I hold very different views about the case, I like and respect him.

He has a profound need for clear answers about who killed his brother. He always believed that Megrahi was guilty and that he had acted on behalf of the Libyan state. He used the opportunity opened by the Libyan revolution to pursue the other alleged state players.

He accepts that the evidence suggesting Megrahi was the clothes purchaser was flawed. Not only was he very much younger, smaller and lighter-skinned than the man described by the shopkeeper, Tony Gauci, but the evidence also suggested that the purchase date was not, as the crown alleged, 7 December 1988, but two weeks earlier, when Megrahi was not in Malta. Ken considers that these weaknesses in the Crown case are relatively insignificant when set again the other evidence that he has unearthed, the most important of which concerns Abu Agila Masud.

We have always known that on the morning of the bombing Masud was on the same flight as Megrahi from Malta to Tripoli and that they had been on other flights together in the previous weeks. Megrahi denied knowing him, as did the Libyans interviewed by Lockerbie investigators prior to Megrahi’s trial. The film reveals that, according to a German court judgment, Masud was the technical mastermind behind the 1986 bombing of La Belle nightclub in Berlin. That attack prompted US air strikes on Libya, which in turn, according to the official Lockerbie narrative, prompted Libya to bomb Pan Am 103. Furthermore, the film suggests, Masud was in the car that greeted Megrahi at the airport on his return to Libya in 2009. Then, earlier this year, a Libyan court convicted him of making booby-trapped car bombs during the 2011 revolution.

The film also focuses on another alleged plotter, Said Rashid, who greeted Megrahi on the steps of the aircraft on his arrival home. Ken got access to Rashid’s abandoned house, where he found diaries in which he had described Malta as a launch pad for terrorism against the west. Malta, of course, was where the Libyans allegedly launched the Lockerbie bomb.

Megrahi was always open about his close relationship with Rashid and other notorious senior security figures, including the newly named suspect Abdallah Senussi, who, like Rashid, was a relation. Megrahi: You are my Jury made clear that both Rashid and Senussi were allegedly involved in terrorism – in Rashid’s case the La Belle bombing.

The evidence that Ken has assembled is substantial and I do not dismiss it out of hand, but, for reasons set out below, I believe the conclusions he has built upon it are unsustainable.

His film has prompted an avalanche of media coverage, almost all of it uncritical. The Crown Office’s chief media cheerleader, Times columnist Magnus Linklater, has even declared that '[it] is time to extinguish the last embers of controversy that have heated the Lockerbie case for so long'. 

Anything that places Lockerbie back in the spotlight is to be welcomed. Unfortunately, however, the coverage of the film is more notable for what it omits than what it reveals.

The first significant omission is a consideration of the evidence from Libya and of Megrahi’s behaviour. At the start of the Libyan revolution four years ago, the former justice minister Mustafa Abdel Jalil claimed to have proof that Colonel Gaddafi ordered the bombing. Since then nothing has emerged publicly from the country’s security archives to implicate the Gaddafi regime and Megrahi in the bombing. Jalil later claimed he had been misquoted and the best he could offer by the way of evidence was the fact that the regime had paid Megrahi’s legal bills. Said Rashid’s papers implicated Rashid in terrorism, but there was nothing new and substantial to demonstrate that he had a role in Lockerbie.

The only genuine document to emerge from the ruins of the old regime that speaks directly to the suspects’ private views on the case is a letter by Megrahi to Senussi, reported on by The Wall Street Journal, in which he protested his innocence. (The WSJ speculated that he might have expected the prison staff to check his mail, but that didn’t happen, as he was free to hand over correspondence to the Libyan consulate staff who frequently visited him.)

Megrahi continued to plead his innocence following his return to Libya in 2009. By then there was nothing for him to lose in admitting his guilt, yet he wouldn’t and he spent much of his remaining time cooperating with me in writing his biography – hardly the actions of a guilty man. The Gaddafi regime also had nothing to lose. In 2004 it made a formal admission of responsibility and paid compensation for the bombing, but only because it was obliged to do so in order to free itself of crippling UN sanctions, which had been imposed under US and UK sponsored Security Council resolutions passed in the early 90s. It never made an unambiguous admission of guilt.

Megrahi didn't act like a terrorist when he was in Malta. Although he travelled on a coded passport under a false name, he went to visit his co-accused Lamin Fhimah’s Maltese business partner, whom he had never met before, and introduced himself under his real name. He then stayed the night at the Holiday Inn, rather than at one of the island’s Libyan-owned hotels, despite having stayed there for two nights only a fortnight earlier under his own name. He kept the passport for 11 years until he went to The Netherlands to stand trial and handed it over to the prosecution; again, not what one would expect of a terrorist.

Megrahi told a number of lies, not least, it seems, about his relationship with Masud, but lies do not prove guilt. Truth telling is a luxury of liberal democracies. In countries like Gaddafi’s Libya it can be fatal.

A second omission is the strong evidence that points away from Megrahi and Libya. Unlike the Libyans, the original suspects in the bombing, the Syrian-based Popular Front for the Liberation of Palestine-General Command (PFLP-GC), had a track record of bombing aircraft. Moreover, they made bombs into Toshiba BomBeat radio cassette players, the same brand – although a different model – that was used to destroy Pan Am 103. According to their bomb-maker Marwan Khreesat, who was arrested in Germany with other members of the group two months before Lockerbie in an operation code-named Autumn Leaves, his fellow arrestee Hafez Dalkamoni had come to Germany to coordinate an attack on a western airline and had shown a particular interest in Pan Am. 

The German cell also had a link to Malta through the Swedish-based terrorist Mohamed Abu Talb, some of whose associates had visited Dalkamoni and Khreesat’s German apartment two weeks before the Autumn Leaves raids, and who himself visited Malta around the same time. 

There have been suggestions that the PFLP-GC and the Libyans somehow joined forces and that the Libyans were responsible for the plot’s final execution. This would make sense if the Autumn Leaves arrests had halted the PFLP-GC’s operation. However, other evidence suggests that it continued. Khreesat told the German police that other members of the group had evaded arrest, including one called Abu Elias, who, Khreesat gleaned, was to have an important role in the planned attack. Another PFLP-GC member called Mobdi Goben, who led the group's Yugoslavian cell and was visited by members of the German cell shortly before their arrest, later claimed that the bombing had been coordinated by Abu Elias. 

Further evidence that the PFLP-GC’s plot remained active after the Autumn Leaves raids came in a warning circulated by the US State Department's bureau of diplomatic security three weeks before Lockerbie (and a few days before the better known and allegedly hoax Helsinki warning). It stated that a group of radical Palestinians in Europe was planning to target Pan Am, adding 'Timeframe is present'. 

A number of declassified US intelligence documents have stated as fact that the bombing was commissioned from the PFLP-GC by Iran in revenge for the accidental shoot-down of Iran Air flight 655 by US battlecruiser the USS Vincennes six months earlier. Former CIA agent Robert Baer revealed specific details of the Iranian/PFLP-GC attack, which he said came from a number of reliable sources. Another, Richard Fuisz, revealed in a court deposition that he was told by numerous senior Syrian officials who were close to PFLP-GC leader Ahmed Jibril that the group was behind the bombing. 

None of this rules out Libyan involvement in the attack: Libya backed the PFLP-GC and may well have provided logistical and material support to the bombers. This scenario was one that neither the Lockerbie prosecutors nor the Libyans themselves would wish explored. 

A third omission is the evidence suggesting that the La Belle bombing was not a straightforward act of Libyan terrorism. Three of the four people convicted of the bombing worked at the Libyan People’s Bureau in East Berlin: Palestinian Yassar Chraidi, Lebanese-born German Ali Chanaa and Libyan Musbah Eter. Eter confessed to his role in the bombing in 1996 and became the key prosecution witness (Chanaa also confessed but his evidence was not relied upon by the prosecution). Also central to the case were files from the former East Germany security service, the Stasi, which documented information provided by its network of informers within Berlin’s Arab community.

The files appeared to corroborate Eter’s claim that Masud was a bomb technician and indicated that he was in Berlin around the time of the bombing. The Libyan witnesses in the Lockerbie case all denied knowledge of Masud. Also important to the case were intercepts of incriminatory messages supposedly sent between the Libyan government and the East Berlin People’s Bureau. Said Rashid was identified as the main voice behind the instructions from Tripoli. Ostensibly, all this was convincing evidence of Masud’s and Libya’s guilt. But other evidence suggests the bombing had some very murky undercurrents.

The Stasi files suggested that the staff of the East Berlin Libyan People’s Bureau were far from being a close band of Gaddafi loyalists. Most startlingly, they showed that Musbah Eter had a long-standing relationship with the CIA. A 1998 investigation by the German TV channel ZDF alleged that, at the time of his confession in 1996, he was running a CIA front company in Malta.

Some of the Stasi’s Arab informants also had a relationship with the CIA. So too did a number of non-Libyans, whom the Stasi files implicated in the wider La Belle plot, but who escaped justice. One key informant, Mahmoud Abu Jaber, and his brother Mohamed, both of whom were both close to Chraidi, ran a freelance Palestinian terrorist cell that was mistrusted by other Palestinians. The Stasi learned that the CIA knew that Mahmoud and another cell member, Khaled Shatta, were involved in the bombing. In the months prior to the attack the cell lived in East Berlin and met the defendants almost daily. Hours before the attack they travelled to West Berlin. Their movements were monitored by both the Stasi and the Soviet intelligence service, the KGB, who concluded that they were working for Western intelligence. A declassified KGB document indicated that Jaber was suspected of being an agent provocateur, who was being used by the CIA to concoct a case against Libya. The KGB reported that, two days before the bombing, he told his CIA contacts that it would cost $30,000, rather than the previously quoted amount, $80,000. Another member of the group admitted to ZDF that he was a Mossad asset.

All this is important in the light of the widely reported and well documented fact that throughout the Reagan presidency the CIA ran a massive covert campaign against Libya. In the run up to the La Belle attack, the US navy conducted aggressive exercises off the coast of Libya, which were clearly designed to provoke a Libyan military response, although none came. The bombing gave the White House hawks the excuse they craved to strike. 

When the US released the incriminatory intercepts to the German authorities a decade after the attack they appeared to be genuine. However, according to former Mossad agent Victor Ostrovsky the Americans were duped by a Mossad, who broadcast phony messages from Tripoli. Neither the La Belle prosecutor Detlev Mehlis nor the FBI bothered to interview Ostrovsky about his claims. 

To be clear, I do not claim that Libya, Said Rashid and Abouagela Masud were not involved in La Belle – I would not be surprised if they were – I merely caution against taking a black and white view of the case.

The fourth major omission in the recent media coverage is the evidence that demonstrates that the Lockerbie bomb did not originate in Malta. To remind you, Megrahi's conviction rested on the belief that he had managed to smuggle a bomb contained in an unaccompanied suitcase on board Air Malta flight KM180 from Malta to Frankfurt and that this case had been transferred to Pan Am feeder flight PA103A to Heathrow, where it was transferred to PA103. The claim relied upon two documents from Frankfurt airport, which, according to the Crown, demonstrated that an unaccounted-for suitcase had been transferred from KM180 to PA103A.

However, that claim in turn relied upon a number of shaky inferences about the documents and the surrounding events at Frankfurt (which are documented in Megrahi: You are my Jury and, more exhaustively, in Dr Morag Kerr's book, Adequately Explained by Stupidity?).

Megrahi's conviction depended upon two still more unlikely assumptions. The first was that he had struck very lucky. Forensic evidence suggested that the bomb's position within luggage container AVE4041 was such that it was as close as it could be to the skin of the aircraft and that had it been any further away it would not have penetrated the skin and caused the plane to disintegrate. 

The second was that he had managed to circumvent Air Malta's baggage loading procedures. Unlike Pan Am's these were unusually strict; they required the head loader to physically count all the bags to make sure the total tallied with the number checked in. To ensure that he had done so, he was not told this number, but instead had to report the total to the flight's ramp dispatcher, who would check it against the checked-in total. KM180's records showed that the numbers had matched. The police investigation established that all these bags had made it onto the flight and been collected by their owners, which ruled out the possibility that Megrahi or an accomplice had managed to swap the bomb suitcase for a check-in bag prior to the head loader's count.

The only witness from any of the three airports investigated by the police who could recall seeing a brown Samsonite case of the type that contained the bomb was a Pan Am loader at Heathrow called John Bedford. On the day of the bombing he was based in the so-called interline shed, which processed bags transferred from other flights, but not those from PA103A from Frankfurt, which allegedly carried the suitcase from Malta.

When interviewed by the police he remembered clearly that it was lying flat in the luggage container AVE4041 in the approximate position that the explosion later took place. He said he noticed it when he returned from his tea break at around 16.45 and that a colleague, Sulkash Kamboj, had told him that he had placed it there. (Kamboj subsequently had no recollection of doing so and there is no suggestion that he was part of the bomb plot.) 

Crucially, Bedford went off duty before PA103A arrived from Frankfurt, so the suitcase he saw could not have originated from that flight and could therefore not have been a rogue suitcase from the Air Malta flight KM180. Equally crucially, he and the two other loaders who saw AVE4041 were sure that, by the time it was taken to PA103A to be topped up with baggage from Frankfurt, the base of the container was covered by a single layer of baggage, which consisted of at least five cases standing vertically along the back and two lying flat at the front.

These details were important because two police memos uncovered during preparations for Megrahi's second appeal showed that only six legitimate interline bags would have been loaded into AVE4041, none of which matched that described by Bedford. Clearly then, the Bedford suitcase was rogue and, to the best of his recollection, it matched the one that contained the bomb.

Further evidence that the bomb was planted at Heathrow has been unearthed and compiled in an exhaustive investigation by researcher Dr Morag Kerr in her book Adequately Explained by Stupidity?. Taken together, the Heathrow evidence is far more convincing evidence of the bomb's origin than the fact that Megrahi and Abouagela Masud left Malta together on the morning of the bombing.

The final important omission is the evidence that destroys the Crown’s central claim that the Lockerbie bomb contained an MST-13 timer from a batch supplied by the Swiss company Mebo to Libya. The claim relied upon a fragment of circuit board known as PT/35(b), which was found within the Lockerbie debris.

According to the Crown, it matched the boards used in the Libyan batch, which had been made for Mebo by another Swiss company, Thüring. However, there was a crucial difference, which was not revealed to the trial court: PT/35(b)’s copper circuitry was plated with pure tin, whereas the boards in the timers supplied to Libya were plated with a tin-lead alloy. In 2008 Thüring’s production director confirmed to Megrahi’s lawyers that the company had only every used tin-lead alloy plating. It meant that the fragment could not have been from one of the MST-13s supplied to Libya. 

As well as omitting such vital evidence, the media coverage surrounding 'My Brother’s Bomber' has swerved an urgent question: given that Abu Agila Masud apparently linked the La Belle attack and Lockerbie, why did the Lockerbie investigators never make anything of the fact? It's clear from the statements of Scottish police officers that Masud was a prime suspect from 1991 onwards. In 1997 he was named in the indictment against the La Belle accused. Had the Lockerbie prosecutors known of the link, they should have used it to bolster the weak circumstantial case that they had assembled against Megrahi and his co-accused, Lamin Fhimah. The fact that they did not looks like a major cock up, which the announcement of the pursuit of the two new suspects has effectively concealed. The Crown Office claims that there is now a 'proper basis' in Scots law to treat the two men as suspects, implying that there wasn’t previously. In fact, such a basis has existed since 1991.

The initiative has already descended into farce. The Crown Office has discussed getting access to the suspects with the internationally recognised government in Tobruk, which is powerless to help, because they are being held by the rival government in Tripoli. That government is willing to allow the Crown Office to interview the suspects, but has heard nothing from them. As leading Libya observer Jason Pack has observed, given the very delicate political situation in the country, which the UN is attempting to resolve by brokering the formation of a national unity government, the Crown Office’s announcement seems 'particularly ill-timed and naïve'.

I can believe that the police and FBI failed to be sufficiently curious about La Belle, but find it hard to believe that the CIA missed the Masud link with Lockerbie. In the official narrative, the two bombings were umbilically linked. The CIA of all people should therefore have been alert to the possibility that there were common players between the two attacks. They could not have been unaware that Masud had been implicated in La Belle if the man who implicated him, Musbah Eter, was one of their own.

Why, then, was it not until 19 years after Eter named Masud, and 18 years after he was named in the La Belle indictment, that the Lockerbie connection was made? And why did it fall to one of the Lockerbie victims' relatives to make the connection? Clearly the Libyans kept silent about Masud because they knew that the La Belle connection, whether genuine or not, would damage Megrahi and Fhimah's prospects at trial, but why the apparent silence from the CIA?

We are unlikely to get answers to these and the many other questions that cloud Lockerbie. We should applaud Ken Dornstein for adding some pieces to the jigsaw. He has seen a picture that he finds convincing, but when I look at the other pieces, I am equally sure he is wrong and that, if we ever get to see the complete picture, the part he has illuminated may prove to be peripheral.

We must nevertheless hope that Masud and Senussi are handed over to the Scottish authorities, unlikely as that prospect may currently seem. The case urgently needs reopening and a trial of the two men may be the best way of achieving it. Should there be one, the prosecution would have to re-run most of the discredited case that convicted Megrahi, and the defence would be armed with vital exculpatory evidence that the Crown previously withheld. The result, I predict, would be a deepening rather than an answering of Lockerbie’s mysteries.
