Some 200,000 guns the US sent to Iraqi security forces may have been smuggled to terrorists , it was feared yesterday. The 99-tonne cache of AK47s was to have been secretly flown out from a US base in Bosnia. But the four planeloads of arms have vanished. Orders for the deal to go ahead were given by the US Department of Defense. But the work was contracted out via a complex web of private arms traders. And the Moldovan airline used to transport the shipment was blasted by the UN in 2003 for smuggling arms to Liberia, human rights group Amnesty has discovered.
