Suicide bombers and a gunman stormed a police station in northern Iraq on Sunday, one of several attacks across the country which left seven dead.
They were the latest incidents in a wave of violence which has claimed more than 2,000 lives since the start of April.
Militants, building on Sunni discontent with the Shia-led government, appear to have grown stronger in central and northern Iraq.
The commander of the army’s 12th division, Brigadier General Mohammed Khalaf, said the assault on the police station near the town of Hawija started with a gunman on foot opening fire on the guards.
A suicide bomber with an explosives-laden belt then blew himself up in the reception area and a suicide car bomber rammed his vehicle into the building, Mr Khalaf added. Three policemen were killed and five others wounded.
In the nearby city of Tuz Khormato two parked car bombs went off in a residential area, killing one civilian and wounding 27 others. Also yesterday, a mortar round hit a motel in central Baghdad, killing three civilians.
