BAGHDAD, Iraq (CNN) -- Seven U.S. Marines were wounded by a roadside bomb that also wounded two Iraqi police officers and killed a civilian interpreter in the Anbar province city of Falluja Friday morning, according to the U.S. military.
The Iraqi Interior Ministry earlier called the attack a suicide car bombing and said that one of its police officers were killed.
An Interior Ministry official said it happened at a checkpoint normally manned by Iraqi police and U.S. troops.
Also on Friday, a suicide bombing outside police headquarters in Falluja wounded four police officers, the official said.
Falluja had been a stronghold for insurgents in the early days of the Iraqi war but is now a center for the "awakening," which opposes al Qaeda in Iraq.
U.S. and Iraqi military operations have chased many al Qaeda in Iraq cells out of Anbar province, according to military accounts.
Those militants have now gained control in other areas, such as Nineveh province, and security forces have embarked on an offensive against them there, officials say.
A U.S. soldier was killed Thursday in a roadside bombing southwest of Baghdad, the U.S. military said Friday, bringing the number of U.S. military personnel killed in Iraq to 4,080.
