At least 51 people have been killed and dozens wounded in a series of bombings and attacks in and around Baghdad.
The explosions Wednesday hit mainly Shi\’ite areas of Baghdad, including the Kazimiyah and Sadr City neighborhoods, leaving at least 140 more people wounded.
There was no immediate claim of responsibility for the attacks.
Tension between Iraq\’s minority Sunnis and the ruling Shi\’ites has been simmering since police cracked down on Sunni protesters in April. The Sunnis accuse the government of marginalizing them politically and ignoring their demands.
United Nations officials say the violence has killed thousands and fear Iraq could be heading toward civil war.
More than 4,000 civilians have been killed and 10,000 more have been wounded so far this year, with Baghdad province worst hit.
