U.S. copter crash kills 10 in Afghanistan

ASADABAD, Afghanistan, May 6 (UPI) -- Ten unidentified soldiers were confirmed killed when a U.S. helicopter crashed in Afghanistan, but witnesses say enemy fire wasn't the cause.

The BBC reports the CH-47 Chinook helicopter crashed near a landing zone in the mountains by Asadabad, the capital of Kunar Province, 150 miles east of Kabul.

U.S. officials confirmed the crash wasn't a result of fighting and that all 10 soldiers on board had died, but didn't say what nationality they were.

The U.S. military has a large base in the area, which is near the Pakistan border.
