While we were in the Balkans word had quickly spread that the Real IRA wanted to buy weapons.
In Belgrade, the capital of nearby Serbia, the local Mafia emailed us to offer a cache of anti-tank missiles, Kalashnikovs, a mortar and illegal landmines for £50,000.
And in neighbouring Montenegro, on the Adriatic coast's version of the Costa Del Crime, another war criminal was selling death on an industrial scale. The man, known as Vesko - a former bodyguard of Serbian warlord Arkan - offered to supply us with 20 rocket-propelled grenades, 20 shoulder-fired missiles and 20 Spider machine guns used by the SAS.
Our contact was the deputy commander of the Kosovo Liberation Army (KLA) Niam Behljulji, known as Hulji. The group were trained by Bin Laden's men. Astonishingly, we met him under the noses of the British Army and UN forces - who remain as peacekeepers following Kosovo's bloody war with Serbia. Hulji, is said to supply terrorists across Europe and has been accused of massacring Serbian women and children during the war. He even posed grinning for a photograph, holding the severed head of one his victims.
