Car bomb kills 4, wounds 6 north of Baghdad

An Iraqi police official says that a bomb planted in a parked car killed four people and wounded six, including three policemen, in the city of Tikrit, north of Baghdad. The official says Tuesday's blast occurred at 7:30 a.m. on a major central street used by local government officials to go to work. The official spoke on condition of anonymity because he is not authorized to speak to the media. Tikrit is Saddam Hussein's hometown and has been a hotbed of the Sunni insurgency since the 2003 ouster of the late Iraqi leader. But it has enjoyed relative quiet since violence levels significantly dropped over the past year in much of Iraq.
