A Black Hawk helicopter crashed Thursday in southern Afghanistan, likely killing all four of its crew members -- all of them Americans -- a U.S. military official said.

The crash occurred in bad weather, though the official said "we cannot yet rule out enemy action."

Troops at a combat outpost in the area waiting to be picked up saw the crash happen, the official said. Another helicopter flying nearby was not affected.
