Another U.S. Helicopter Lost in Iraq

A U.S. Army helicopter crashed Friday in a hail of gunfire north of Baghdad, police and witnesses said -- the fourth lost in Iraq in the last two weeks. The U.S. command said two crew members were killed, and the top U.S. general conceded that insurgent ground fire has become more effective.

A brief U.S. military statement gave no reason for the crash and did not identify the type of aircraft. A Pentagon official said it was an Apache attack helicopter, which carries two crew members.
