In a separate statement, the military says U.S. Marines and Iraqi security forces are continuing operations in and around the city of Karabilah in western Anbar province, where several car bombs were discovered Monday.

On Monday, insurgents carried out at least six car bomb attacks across Iraq, killing at least 23 people.

The deadliest attack occurred in the Kurdish city of Arbil, where a suicide bomber dressed as a policeman drove into a crowd of Iraqi police recruits, killing 13 of them and wounding 100 others.

At least 10 other people were killed in separate attacks in Baghdad and the oil city of Kirkuk, north of the capital.
