Iraqi gunmen shot at a U.S. military helicopter in northern Iraq Saturday forcing it to make an emergency landing in which two of the crew were injured.
Security sources said the helicopter was hit during fighting between gunmen and U.S. forces in Tal Afer, 40 miles (70 kilometers) west of the northern city of Mosul.
Witnesses said two U.S. military vehicles were set ablaze during the fighting that broke out during the early morning hours in the mainly-Sunni region.
In Baghdad, mortars slammed into the heavily-guarded Green Zone next to the building where the Iraqi National Council has been meeting. No casualties were reported.
