A former Soviet army officer has been convicted by a US jury of planning and leading a Taliban attack on American forces in Afghanistan in 2009.
The jury found Irek Hamidullin guilty on 15 counts, including supporting terrorists and conspiracy to use a weapon of mass destruction.
The 55-year-old is the first military prisoner from Afghanistan to be tried in a US federal court.
Some of the charges carry a mandatory life sentence.
About 30 insurgents died in the attack, with Hamidullin the only survivor, while no American or Afghan soldiers were killed.
