Suspected Al-Qaeda gunmen, some wearing army uniforms, raged through a western Iraq city on Monday in a pre-dawn shooting spree that killed 27 policemen, including two officers killed execution-style. The assault, launched at about 2:00 am (2300 GMT on Sunday), saw insurgents dressed in military uniforms simultaneously attacking two checkpoints in the east and west of Haditha before storming other security posts and raiding the homes of the two officers. Monday’s violence, the deadliest in Iraq since February 23, comes just weeks before an Arab League summit due to be held in Baghdad at the end of the month. “We received 27 dead bodies, all of them policemen, and treated three policemen who were wounded,” Fadhil al-Nimrawi, director of Haditha’s hospital, told AFP. He added that the hospital also received the body of a gunman.
