BAGHDAD, Feb. 17 (Xinhua) -- At least 15 people were killed and 80 others wounded in a series of car bomb explosions mainly targeting Shiite districts in the Iraqi capital of Baghdad on Sunday, an Interior Ministry source told Xinhua.
"Our latest report said that 15 were killed and some 80 wounded by nine car bomb explosions in Baghdad," the source said on condition of anonymity.
The attacks occurred around 11:00 a.m. (0800 GMT), when three car bombs went off at Sadr City district, while two car bombs hit al-Husseiniyah district and one in al-Ameen, Kamaliyah, Karrada and Saidiyah districts each, the source said.
The attacks mainly targeted crowded marketplaces and parking lots with the aim of causing heavy casualties, the source added.
No one has so far claimed responsibility for the attacks, but al-Qaida front in Iraq frequently claimed the responsibility of most deadly attacks in the country, raising fears that the terrorist group could return to widespread violence.
Violence and sporadic high-profile bomb attacks are still common in Iraqi cities despite the dramatic decrease in violence since its peak in 2006 and 2007, when the country was engulfed in sectarian killings.
