BAGHDAD- A coordinated wave of car bombings tore through mostly Shiite areas of Baghdad on Monday, killing at least 66 people and maiming nearly 200 as insurgents step up the bloodshed roiling Iraq.
The attacks in markets and other areas frequented by civilians are the latest sign of a rapid deterioration in security as sectarian tensions are exacerbated by anti-government protests and the war in neighboring Syria grinds on.
More than 450 people have been killed across Iraq in May. Most of the killings came over the past two weeks in the most sustained wave of violence since U.S. troops left in December 2011.
Iraqis gather at the scene of a car bomb attack at a used cars dealers parking lot in Habibiya neighborhood of eastern Baghdad, Iraq, Monday.
The surge in attacks is reminiscent of the sectarian carnage that pushed Iraq to the brink of civil war in 2006 and 2007.
April was Iraq's deadliest month since June 2008, according to a United Nations tally that put last month's death toll at more than 700.
There was no immediate claim of responsibility for Monday's bombings, but they bore the hallmarks of al-Qaida's Iraqi arm. The group, known as the Islamic State of Iraq, frequently uses car bombs and coordinated blasts against Shiites to undermine Iraqis' confidence in the Shiite-led government.
The day's deadliest attack happened when two bombs exploded in the eastern Habibiya area on the edge of the sprawling Shiite district of Sadr City. Those blasts killed 12 and wounded 35, police said.
Twin blasts also struck an open-air market in the predominantly Shiite al-Maalif area, killing six and wounding 12.
Elsewhere across the bloodied capital city, police reported:
- A car bomb went off in the eastern New Baghdad area as officers were waiting for explosives experts to dismantle it. A civilian was killed and nine others wounded.
- In the north, a blast in the Sabi al-Boor neighborhood killed eight civilians and wounded 26. In the Kazimiyah district, a car bomb blew up near a bus and taxi stop, killing four and wounding 11.
Another blast killed four and wounded nine in the Shaab area. And an attack in the Hurriyah neighborhood left five dead and 14 wounded.
- A bomb in the southwestern neighborhood of Bayaa killed six civilians and wounded 16.
- In Baghdad's central Sadria area, a car bomb killed three civilians and wounded 11.
- In the east, a blast killed five and wounded 12 in the Jisr Diyala area. Car bombs also struck the Baladiyat neighborhood, killing four and wounding 11.
- And in Madain, about 12 miles south of central Baghdad, a car bomb killed three and wounded nine.
