BAGHDAD, June 22 (Xinhua) -- Seven policemen were killed and 13 people injured when a suicide car bomber struck a local municipality building and a nearby police station in a town to the west of Baghdad on Monday, a well-informed police source said.
The suicide bomber drove his explosive-packed car into the checkpoint outside the local government compound in the mainly Sunni Arab town of Abu Ghraib, some 20 km west of Baghdad, the source told Xinhua on condition of anonymity.
The blast killed seven policemen and wounded 13 people, most of whom were police forces, destroying part of the compound building, the source said.
The attack took place during the presence of U.S. troops in the compound, the source said without providing further details about the incident.
Meanwhile, residents of the town said the U.S. soldiers also sustained some casualties.
Earlier in the day, the police reported separate attacks in Baghdad, which killed a total of 13 people and wounded 78 others.
The attacks came a few days ahead of the scheduled pullout of U.S. troops from Iraqi towns and cities by the end of the month.
Violence in Iraqi cities has dropped dramatically in recent months, but attacks remain common, particularly in Baghdad.
