Suicide bombers and gunmen killed at least 54 people in Iraq.
Al Qaeda-linked militants have intensified attacks on the security forces, civilians and anyone seen as supporting Iraqi government in Baghdad, tipping Iraq back into its deadliest levels of violence in five years.
In Baiji, 180 km north of Baghdad, four men wearing explosive belts took over a police station after detonating a car bomb parked outside. And then blew themselves up inside the station, killing five policemen. The other two did the same about an hour later as Iraqi special forces counter-attacked.
No group immediately claimed responsibility for the attack, but suicide bombings are the trademark of al Qaeda's Iraqi wing, which merged this year with its Syrian counterpart to form the Islamic State of Iraq and the Levant (ISIL).
