In the basement of a bombed-out al-Qaeda arms storage building in eastern Aleppo last year, I found a weapons log book from a mortar factory in Bosnia – with the handwritten name of one of their senior officials, Ifet Krnjic, on each page. It was dispatched from the Balkans with a cargo of 500 120mm mortars in January 2016. But now, in the forested heart of central Bosnia, I have found Mr Krnjic, who says his company sent the arms to Saudi Arabia.
Sitting on the lawn of his home south of the weapons-manufacturing town of Novi Travnik, he brings his finger down onto the first page of the log book which I showed him. “This is my signature! Yes, that’s me!” Krnjic exclaims loudly. “It’s a warranty for the 120mm mortar launcher – this is Nato standard. It [the shipment] went to Saudi Arabia. It was part of a supply of 500 mortars. I remember the Saudi shipment well. They [the Saudis] came to our factory to inspect the weapons at the beginning of 2016.”
