A senior Iraqi military commander says gunmen have attacked a police station north of Baghdad and killed three policemen.

The commander of the army's 12th Division, Brig. Gen. Mohammed Khalaf, says the Sunday attack near the city 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.

Khalaf added that three policemen were killed and five others wounded.

Hawija, a former insurgent stronghold, is about 240 kilometers (150 miles) north of Baghdad.

The attacks are the latest in a wave of killing that has claimed more than 2,000 lives since the start of April.
