A suicide car bomber targeted the governor's offices in the predominantly Shiite southern city of Hillah on Monday, killing at least eight people and wounding 31.
It was the second attack in three days. A parked car packed with explosives blew up on Saturday in the center of the city, 95 kilometers (60 miles) south of Baghdad.
The explosion on Monday occurred about 6:30 a.m., a spokesman for the provincial police department said. He said the eight killed included three policemen and at least four officers were among the 31 wounded. The spokesman spoke on condition of anonymity because of security concerns.
