Iraqi authorities say a car bomb has killed two police officers and injured eight civilians west of Baghdad. Maj. Gen. Tareq Youssef, the police chief of Anbar province, says the attack happened Monday morning near local government offices on the main street of Ramadi, the Associated Press reported. He says a police patrol arrived to check on a car parked in a non-parking zone, and that the car exploded soon afterward. In the northern city of Mosul, police say gunmen killed two traffic policemen in separate attacks also on Monday morning.
