Two Blackhawk helicopters
crashed, wounding four and killing one. The crash took place in the Iraqi capital's Sunni district of Adhamiyah. One Iraqi was killed and two Americans and two Iraqis wounded in the crash.

A Reuters TV cameraman in the Sha'ab district, near Adhamiya, said he saw two helicopters circling overhead as the engine of one of them made a thudding sound as it lost altitude and crashed.
The cameraman said he heard an explosion after the impact, followed by the sound of shooting.

The crash happened 17 days after another US military helicopter crashed in southern Iraq, killing all seven soldiers on board.
