BAGHDAD (Reuters) - An Iraqi militant group issued footage Sunday of a man it said was a captured U.S. Marine and threatened to behead him, further heightening tension ahead of the June 30 formal handover of sovereignty.
Video shown on Qatar-based Arabic channel Al Jazeera showed a blindfolded man in a camouflage uniform, and an apparent Marine Corps identity card that named him as Wassef Ali Hassoun.
