A suicide bomber driving a car and gunmen wearing police uniforms killed at least 33 people in the Iraqi city Kirkuk on Sunday (February 3) when they tried to storm the police headquarters.
The huge car bomb blast tore into the police directorate's concrete facade, destroying cars outside, and leaving bodies under rubble at nearby government offices. Police said there were at least two gunmen.
Several armed groups are active in Kirkuk, and Sunni Islamist insurgents tied to al Qaeda often attack security forces in an attempt to undermine Shi'ite Prime Minister Nuri al-Maliki's government and stoke sectarian tensions.
