Iraqi police say a suicide attack in the northern city of Baiji has killed at least seven people and wounded at least 13.
Police say the bomber rammed a vehicle into a police building in a residential area Saturday. Baiji, about 250 kilometers north of Baghdad, has the country's largest oil refinery and is a key export point for crude oil.
Also, a possible rocket or bomb attack has killed a local leader of the movement of radical Shi'ite cleric Moqtada al-Sadr. Iraqi authorities say Uday Hamid and his wife and two children were killed in an explosion at their home south of Baghdad, in Numaniya.
In other news, the U.S. military says coalition forces killed 12 terrorists and detained 13 suspects in operations today targeting al-Qaida in Iraq networks in central and northern Iraq.
