At least a civilian was killed and 10 others wounded in a car bomb explosion at a parking lot in a town south of Baghdad on Thursday, a well-informed police source said. A booby-trapped car parked at the main parking lot in the town of Yousifiyah, some 25 km south of Baghdad, detonated during the morning rush hour, the source told Xinhua on condition of anonymity. The toll could rise, the source said, citing first police reports about the incident. Iraqi security forces cordoned off the area to secure the scene, while ambulances and civilian cars were transporting the victims to the town's hospital, he said. Yousifiyah is part of once restive area, dubbed Triangle of Death, which is a cluster of towns scattered north of Hilla City, the capital of Babel province, some 100 km south of Baghdad.
