In the deadliest incident, officials said a suicide car bomber killed three people when he targeted a police patrol in Anbar province, west of the capital, Baghdad Thursday. They said at least one police officer was among those killed.
In Baghdad, police said a bomb attached to a minibus exploded Thursday, killing at least one person and wounding seven others.
Meanwhile in western Iraq, the U.S. military said a civilian cargo aircraft crashed shortly after take-off Thursday with four to six crew members on board.
The military said it does not know the fate of the passengers or the aircraft, which reported a malfunction while traveling near the city of Fallujah.
Also Thursday, officials said a roadside bomb wounded six people at a police patrol in central Baghdad, while a parked car bomb wounded at least 16 others in the northern city of Mosul.
Last month Iraqi and U.S. officials noted that violence had dropped to a four-year low, but attacks have become more frequent in the last two weeks.
