BAGHDAD, Iraq — Two U.S. Marines were killed in action yesterday in Anbar Province, the military announced.

Earlier yesterday, the military had said Marines had suffered an undisclosed number of casualties in a suicide car bombing in Ramadi, 70 miles west of Baghdad.

Marines sent to check a suspicious vehicle came under small-arms and rocket-propelled-grenade fire and the vehicle exploded, a spokesman said.

Ramadi is in Anbar Province, but the spokesman — consistent with Marine policy — would not say whether the deaths occurred in the car bombing.

As of yesterday, at least 1,366 members of the U.S. military have died since the U.S. invasion of Iraq in March 2003, according to an Associated Press count. At least 1,073 died as a result of hostile action.
