A helicopter from a unit based at Fort Carson, Colorado crashed in Iraq Wednesday.

Two pilots died when the chopper crashed into the Euphrates River west of Baghdad.

The OH58 Kiowa helicopter was assigned to the Third Armored Cavalry Regiment based at Fort Carson.

One witness reported seeing a missile hit one of two U.S. choppers flying in the area. Another witness said the helicopter that went down was on fire before the crash.

The United States has lost 15 helicopters in Iraq overall since May. 62 Americans have been killed in the crashes.

The latest news came as several troops arrive home to Fort Carson this week.

Forty-one Fort Carson soldiers and two reservists have died in Iraq since the war began.
