"A suicide bomber drove an explosive laden vehicle into a police station in western Mosul, killing seven people, most of them were policemen," Yasir Hammad, an officer from the city police told Xinhua by telephone.
The blast also wounded 28 people, including policemen along with destroying parts of the police station's building, he said.
