A suicide car bomber killed up to 16 people near an entrance of the Interior Ministry in Baghdad on Monday (August 28), a source in the ministry said. Thirteen of the dead were policemen, police said. Sixty-two people were wounded, 47 of them police. The attack came a day after a spate of car bombings and shootings across Iraq killed about 60 people as thousands of U.S. and Iraqi troops pressed on with a major operation to restore calm to the Iraqi capital. On Sunday (August 27) gunmen opened fire on a market area in Khalis, a town north of Baghdad, killing 16 and wounding 25 other people, police said. Khalis is a religiously mixed town 80 km (50 miles) north of Baghdad that has been the scene of sect arian violence in the past. The motive of the attack was not immediately clear. Two simultaneous suicide car bombs killed nine people and wounded 22 in the ethnically disputed city of Kirkuk, 250 km (155 miles) north of Baghdad on Sunday (August 27). One blast hit the house of a local police officer and a second struck the residence of a relative of Iraq's president Jalal Talabani. He was not hurt. Violence claimed the lives of more than 3,000 Iraqis in July.
