BAGHDAD: Insurgents Monday killed at least eight people in Iraq, including three policemen, officials said as the war-torn country s security forces continued to bear the brunt of rebel violence. A roadside bomb killed a policeman in the flashpoint southern Baghdad district of Dura, a center of deadly feuding between Baghdad s rival Sunni and Shiite death squads, a security official said. Another device exploded in a Baghdad square as police investigated an earlier explosion that had not caused any casualties, injuring three officers, he added. In the restive province of Diyala, northeast of Baghdad, six people were killed in a string of incidents, five of them civilians and one a policeman. In the town of Musayib, a policeman was killed when a mortar round fell near his police station. At least 15 other people were wounded in the attack. Meanwhile, police found another 14 corpses, including three in western Baghdad and four in the northern oil city of Kirkuk. Iraq is in the grip of a bloody sectarian conflict between rival militias. The United Nations estimates that more than 100 people are killed every day in attacks by death squads and militant groups. AFP
