Iraqi police say 11 people have been killed in suicide bomb attacks targeting an officer in an Iraqi special forces unit in Samara, north of Baghdad. The officer escaped injury.

In the first attack, a suicide bomber blew himself up outside the home of the officer, killing and wounding people in the street, but not harming anyone in the house.

Shortly afterward, two people identified as insurgents tried to set a bomb outside the same house. They were killed by their bomb.

Earlier, in an attack overnight, eight policemen were killed when insurgents struck a police station near the city of Ramadi, the capital of Anbar province.

Police and other members of Iraq's security forces are frequently targeted by insurgents, who regard the security personnel as collaborators with U.S. troops.
