A suicide car bomber struck an Iraqi army in Salahudin province to the north of Baghdad on Sunday, killing two soldiers and wounding 12 people, a provincial police source told Xinhua. A suicide bomber drove his explosive-laden car into an Iraqi army checkpoint in the south of the city Dujail, some 60 km north of Baghdad, killing two soldiers and wounding four others, the source said on condition of anonymity. Eight civilians were among the wounded people by the blast which also destroyed several civilian cars at the scene, the source said. Iraqi security forces sealed off the area to secure the scene as ambulances and civilian cars evacuated the casualty, the source added. Salahudin province, located in northern central Iraq, is a Sunni-dominated province. Its capital city of Tikrit, some 170 km north of Baghdad, is the hometown of former President Saddam Hussein. Sporadic attacks are common in Iraqi cities as the U.S. troops fully withdrew from the country according to security pact signed between Baghdad and Washington in late 2008.
