On trial for war crimes – Tony Blair’s former allies

by Mark Curtis, Declassified UK, 12 April 2023

Four members of the Kosovo Liberation Army (KLA) are being tried at The Hague for war crimes during the 1999 conflict over Kosovo. In that war, the KLA was seen by the UK as terrorists but was covertly and overtly supported by the Labour government.

  • Blair’s foreign secretary Robin Cook was in direct touch with KLA leader Hashim Thaci, now on trial for war crimes, during the Kosovo war 
  • UK secretly gave military training to the KLA while it had working links to Al-Qaida 
  • Blair denied in parliament the UK was training the KLA

NATO’s bombing campaign against Slobodan Milošević’s Yugoslavia in 1999 is routinely presented as an “humanitarian intervention”. Tony Blair has long been praised for coming to the defence of ethnic Albanians in the territory of Kosovo who were subject to increasingly brutal abuses by the Yugoslav army from the end of 1998. 

The Kosovo Liberation Army fought Yugoslav forces until the 78-day NATO air campaign, begun in March 1999, forced Milošević’s army from Kosovo. Before and during the war Britain collaborated with the KLA which essentially acted as NATO’s ground forces in Kosovo. 

Fourteen years on, the KLA’s former leader, Hashim Thaci, and three other senior members are now on trial charged with war crimes and crimes against humanity, including murder, enforced disappearances, persecution, and torture. 

The prosecutor in The Hague alleges that the four formed part of a joint criminal enterprise to control Kosovo by “unlawfully intimidating, mistreating, committing violence against, and removing those deemed to be opponents.” 

The victims of these alleged crimes include Serbs, Roma and ethnic Albanians who were considered collaborators with Serbian forces or political opponents of the KLA.

‘Terrorist group’

The KLA comprised ethnic Albanians committed to securing independence for Kosovo from Yugoslavia and promoting a ‘Greater Albania’ in the sub-region. 

The force consisted of a mix of radicalised youths and students, professionals such as teachers and doctors, members of influential families and local rogues. It took to armed struggle and made its military debut in early 1996 by bombing camps housing Serbian refugees from the wars in Croatia and Bosnia and by attacking Yugoslav government officials and police stations. 

By mid-1998 the KLA controlled a large segment of Kosovo and had armed and organised thousands of fighters. It was a formidable force on the ground when, amidst a growing civil war, the Yugoslav army launched a brutal full-scale offensive in Kosovo in March 1999.

From its inception, the KLA targeted Serbian and Albanian civilians, especially those considered collaborators with the authorities. Declassified British documents show the chair of the Joint Intelligence Committee, Michael Pakenham, writing in September 1998 that the KLA is “exploiting the plight of civilians, and itself appears to have committed atrocities against Serbs”.

The US and Britain clearly recognised the KLA as a terrorist organisation. In February 1998, the Clinton administration’s special envoy to Kosovo, Robert Gelbard, described the KLA as “without any question a terrorist group”. 

Similarly, foreign secretary Robin Cook told parliament in March 1998: “We strongly condemn the use of violence for political objectives, including the terrorism of the self-styled Kosovo Liberation Army.” 

Indeed, in November 1998, and again in January 1999, Cook said that “most of the killings” in Kosovo recently had been carried out by the KLA, whose activities against ordinary Kosovars were only serving to “prolong their suffering”. 

Parliamentary statements by British ministers make clear that they continued to regard the KLA as a terrorist organisation right up to the beginning of the bombing campaign in March 1999. 

“We condemn their violent activities”, said an internal Foreign Office brief about the KLA in August 1998. 

Indeed, the files from 1998 clearly show that British officials were concerned that air strikes against Yugoslavia that they were then considering would empower the KLA and its claims to full independence for Kosovo, to which Whitehall was opposed. 

British planners even considered military action against the KLA at this time but ruled it out as impractical.

The KLA was also widely known to be involved in heroin trafficking into Britain while MI6 was investigating its links to organised crime. Brian Donnelly, Britain’s ambassador to Yugoslavia, wrote in June 1998: “Some, at least, in the KLA are likely to be the first cousins of the Albanians who are running organised crime and drug running throughout Europe”. 

Al-Qaida connections

The KLA had also developed connections to al-Qaida. Osama Bin Laden reportedly visited Albania and established an operation there in 1994. In the years preceding the NATO bombing campaign, more Al-Qaeda militants moved into Kosovo to support the KLA, financed by sources in Saudi Arabia and the United Arab Emirates. 

By late 1998, the head of Albanian intelligence was saying that Bin Laden had sent units to fight in Kosovo. Al-Qaeda was said to be helping hundreds of foreign fighters to cross from Albania into Kosovo, including veterans of the militant group Islamic Jihad from Bosnia, Chechnya and Afghanistan, carrying forged passports.

Numerous KLA fighters had trained in Al-Qaida camps in Afghanistan and Albania. One of the “links” between Bin Laden and the KLA said to have been identified by US intelligence was “a common staging area in Tropoje, Albania, a centre for Islamic terrorists”. 

One KLA unit was led by the brother of Ayman al-Zawahiri, then Bin Laden’s right-hand man, according to a senior Interpol official who later gave evidence to the US Congress. 

Asked in parliament in November 1998 about a media article stating that mujahideen fighters had been seen with KLA forces in Kosovo, Robin Cook stated: “I read that report with concern.”

In March 1999, his deputy, foreign minister Tony Lloyd, told the House of Commons that the government was aware of media reports of contacts between Islamic terrorist groups and the KLA but “we have no evidence of systematic involvement”. 

The use of the word “systematic” was probably carefully chosen to imply that the government had some knowledge.


At some point in 1996 British intelligence, along with the US and Swiss services, made its first known contact with a senior KLA official in Albania, likely to have been Shaban Shala, a commander who would fight in Kosovo in 1999 and also inside Serbia in 2000. 

Formal contacts between the KLA and the US took place in July 1998 when Chris Hill, the US special envoy for Kosovo, met KLA officials. The following day a British diplomat also met KLA officials in their headquarters in the central Kosovan village of Klecka.

The UK government later claimed that “an initial meeting” between an official in the British embassy in the Yugoslav capital, Belgrade, and KLA leaders was held on 30 July 1998. If so, this came two days after foreign minister Baroness Symons recognised in an answer to a parliamentary question that the KLA was a “terrorist” organisation and that “it was clear” that it had “procured significant quantities of arms in Albania”. 

By October, Robin Cook was making clear that Britain was opposed to the KLA’s political objective of forging a Greater Albania. “There is no place on the international map for a greater Albania – any more than there is for a greater Serbia or a greater Croatia,” he said. 

Yet it was around this time that Britain started to train the forces it not only recognised as terrorists, but whose political agenda it was opposed to and which had links to Al Qaida.


At some point in late 1998, the US Defence Intelligence Agency approached MI6 with the task of arming and training the KLA, the Scotsman newspaper later reported. 

A senior British military source told the paper: “MI6 then subcontracted the operation to two British security companies, who in turn approached a number of former members of the (22 SAS) regiment. Lists were then drawn up of weapons and equipment needed by the KLA.” 

“While these covert operations were continuing,” the paper noted, “serving members of 22 SAS regiment, mostly from the unit’s D squadron, were first deployed in Kosovo before the beginning of the bombing campaign in March.” 

A few weeks into the bombing campaign, the Sunday Telegraph reported that KLA fighters were receiving SAS training at two camps in Albania, one near the capital Tirana, and the other near the Kosovan border, most likely close to the town of Bajram Curri. 

This was the centre of the KLA’s military operations, where a series of training camps were dotted along the hills and from where arms were collected and distributed. It was also where jihadist fighters had their centre and common staging area with the KLA, as noted by the previous US intelligence reports. 

The British training reportedly involved instructing KLA officers in guerrilla tactics and weapons handling, demolition and ambush techniques, as well as conducting intelligence-gathering operations on Serbian positions. 

The covert operation was reportedly funded by the CIA while the German secret service, the Bundesnachrichtendienst (BND), provided weapons and training.

‘Arms supermarket’

The British government was made aware of arms supplies to the KLA taking place near the Albanian border with Kosovo by at least June 1998.

The declassified files show that it was then that a confidential report was sent to Blair by Paddy Ashdown, a former special forces officer who then led the Liberal Democrats, following a visit to the Balkans. 

Ashdown reported the Albanian view that arms were being transported to the KLA by the Albanian mafia. “Clandestine arms ‘supermarkets’” had been set up on the Albanian/Kosovo border “at which the KLA units and individuals on their way from abroad to join the KLA are able to purchase their needs”, he wrote

Ashdown also visited Bajram Curri and noted that Tropoje was “almost certainly the main center [sic]” for supplying arms to the KLA. Albania’s police authorities “are certainly turning a blind eye to what is happening”, he wrote.

Ashdown also wrote that the Albanian government “have evidence of Islamic attempts to infiltrate the KLA (especially from Iran) but believe this has been unsuccessful”. 


The British training was kept secret. Ministers consistently denied any knowledge of the KLA’s sources of arms or training when asked in parliament. 

On 13 April 1999, three weeks after the NATO bombing campaign began, and just days before the Telegraph reported the British training, Tony Blair told parliament, saying “our position on training and arming the KLA remains as it has been – we are not in favour of doing so … We have no plans to change that.” 

Sometimes ministers used revealing language. Baroness Symons stated on two occasions, in March and May 1999, that there was “no firm evidence” and “no reliable information” on the KLA’s sources of weapons and training. The use of the words “firm” and “reliable” is revealing, being a common method officials use to feign ignorance of issues they are aware of. 

One reason for secrecy was that such training was in violation of UN Security Council Resolution 1160, which forbade arming or training forces in all Yugoslavia.

James Bissett, a former Canadian ambassador to Yugoslavia and Albania, later wrote that the US training of the KLA in 1998 involved “sending them back into Kosovo to assassinate Serbian mayors, ambush Serbian policemen and intimidate hesitant Kosovo Albanians”. 

“The hope”, he added, “was that with Kosovo in flames NATO could intervene and in so doing, not only overthrow Milosevic the Serbian strongman, but, more importantly, provide the aging and increasingly irrelevant military organisation [NATO] with a reason for its continued existence”. 

KLA leader Hashim Thaci explained that “any armed action we undertook would bring retaliation against civilians [by Serbian forces]. We knew we were endangering a great number of civilian lives”. 

‘Eyes and ears’ 

The KLA certainly proved useful to Anglo–American planners. Blair stated a month into the NATO bombing campaign that “the KLA is having greater success on the ground in Kosovo and indeed has retaken certain parts of it”. 

Described in media reports as NATO’s “eyes and ears” on the ground in Kosovo, the KLA was using satellite telephones to provide NATO with details of Serbian targets, according to reports in the British media. 

Some of this communications equipment had been secretly handed over to the KLA a week before the air strikes began by US officers acting as “ceasefire monitors” with the Organisation of Security and Cooperation in Europe. They were, in reality, CIA agents. 

They also gave the KLA US military training manuals and field advice on fighting the Yugoslav army and police. The Sunday Times reported that several KLA leaders had the mobile phone number of General Wesley Clark, the NATO commander. 

Robin Cook, meanwhile, held a joint press conference with KLA representatives at the end of March 1999 and was in direct telephone contact with its commander in Kosovo, Hashim Thaci, the British media reported.

Thaci was “rang up regularly” by Cook “to get information about what was happening in Kosovo”, Labour MP Alice Mahon told parliament later in 1999.

By May, the Independent was reporting that British and US special forces have “gone on the offensive in Kosovo” and were working behind Serb lines “with the help of KLA men hand-picked from camps in northern Albania”. 

It said that units of up of 20 to 30 Allied soldiers were working with up to 100 KLA men and quoted a senior KLA commander saying the UK and US soldiers “either wore uniforms that could not be traced to any Allied unit or were disguised in the combat fatigues of the ‘Black Hand’ Serb paramilitaries”.

Soon after the bombing had begun, in early April 1999, more than 500 Albanians living in Britain volunteered to go to fight in Kosovo, according to KLA representatives in London, though they were likely exaggerating the numbers. 

Just as during the Bosnian War a few years earlier, Britain and the US allowed, and may have facilitated, British and other Muslims to travel to Kosovo volunteering for the jihad. 

Macedonian campaign

US covert support of the KLA guerrillas did not stop when NATO’s Kosovo campaign was brought to an end in June 1999, or even with the fall of Milosevic in October 2000. 

After the Kosovo conflict, KLA forces launched new wars in southern Serbia and Macedonia to promote their aim of a Greater Albania, both of which were initially supported by the US – but, not, apparently, by Britain. 

In March 2001, KLA guerillas began to operate across Kosovo’s nearby border with Macedonia, led by several commanders previously trained by British forces for the Kosovo campaign.

Now fighting under the banner of the National Liberation Army (NLA), formed in early 2001, two of the Kosovo-based commanders of this push into Macedonia had been instructed by the SAS and the Parachute Regiment at the camps near Bajram Curri in northern Albania in 1998 and 1999. 

One was organising the flow of arms and men into Macedonia, while the other was helping to coordinate the assault on the town of Tetevo in the north of the country near the border with Kosovo.

NLA forces were being called “terrorists” by Robin Cook and “murderous thugs” by NATO Secretary-General Lord Robertson, just as they had been before the March 1999 bombing campaign, when, as the KLA, the British were cooperating with them. 

Arms supplies to the NLA from the US helped the guerillas take control of nearly a third of Macedonia’s territory by August 2001. Soon, however, Washington, under pressure from its NATO allies, started to rein in its proxy force and throw its weight behind peace talks.

Thaci emerged from the diplomatic settlement to the Kosovo war as the leader of the strongest faction within the KLA and became Kosovo’s first prime minister. After elections in 2016, he became the territory’s president, resigning in 2020 after the war crimes charges were brought.

In addition to Thaci, also on trial in the Hague are Kadri Veseli, former head of the KLA’s intelligence service, Rexhep Selimi, head of the KLA’s operational directorate, and Jakup Krasniqi, a member of the KLA’s political directorate.
