Two U.S. Marines were killed in action in Iraq's (search) western Anbar province, and a soldier died near the restive northern city of Mosul, the U.S. military said Friday.

The two Marines who died Thursday belonged to the 1st Marine Expeditionary Force, a military statement said. It gave no further details. Anbar province is home to the cities of Fallujah (search) and Ramadi, where U.S. forces have frequently clashed with insurgents.

A 1st Infantry Division soldier also died Thursday while supporting Task Force Olympia (search) operations near Mosul, the military said. Mosul has also seen increased violence since insurgents that were headquartered in Fallujah were driven out of that city in November's U.S. assault.

The deaths brought to 1,359 the number of American troops killed in Iraq since the invasion in March 2003.
