BAGHDAD, Sept. 9 (Xinhua) -- Four car bombings rocked the Iraqi capital of Baghdad on Sunday night, killing at least 16 people and wounding 77 others, an Interior Ministry source said.
The first car bomb exploded at the entrance of Washash neighbourhood in western Baghdad, leaving seven people dead and 21 others wounded, the source told Xinhua on condition of anonymity because he is not authorised to talk to the media.
The second bomb ripped through a popular restaurant in Shula district, northwest of Baghdad, killing five people and wounding 38, he said. The third explosion happened near a pet market in Hurriya district northwest of Baghdad, killing three people and wounding 14 others.
The fourth car bomb struck a popular market in Nahrawan area east of Baghdad, leaving one civilian dead and four others wounded.
In a separate incident, unidentified gunmen attacked an army checkpoint in Abu Ghraib area, some 25 km west of Baghdad, killing three soldiers. The security forces during the exchange of fire killed two militants and arrested another.
A series of bombs and gunfire attacks across Iraq earlier in the day killed at least 52 Iraqis and wounded more than 200 others, in what appeared to be an attempt by insurgent groups to destabilize the country and undermine confidence in the Iraqi government.
