A suicide bomber blew himself up Wednesday inside a police station in a town in Diyala province, killing three policemen and wounding five others, a local police source said.
"Three policemen were killed and five others injured including two civilians when a suicide bomber wearing an explosives belt blew himself up inside a police station in Balad Ruse town Wednesday afternoon," the source told Xinhua on condition of anonymity.
Balad Ruse town is located in the restive province of Diyala, which has recently witnessed an upsurge of bombings and attacks. On March 2, corpses of 14 Interior Ministry employees, who were allegedly kidnapped by a Sunni militant group, were found in the province.
Also on Wednesday, an Iraqi police captain was killed and two policemen were wounded in a roadside bomb attack in a neighborhood in eastern Tikrit, some 170 km north of Baghdad, a local police source said.
Violence continues infesting Iraq despite the presence of tens of thousands of U.S. and Iraqi soldiers across the country in a major security crackdown aimed at curbing insurgency and sectarian violence in the war-torn country.
