A wave of bombings has killed at least 44 people in the Iraqi capital.
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.
