Police in Iraq say car bombs have ripped through Baghdad's Sadr city district, killing at least 37 people and wounding about 100 others.
Authorities say the apparently coordinated blasts hit two markets in the mainly Shi'ite area shortly before sunset, on what came to be one of the deadliest days in the capital in weeks. Sunni insurgents have sought to spark sectarian violence by repeatedly targeting the majority Shi'ite population, while Shi'ites have been blamed for reprisal killings.
Earlier Sunday, at least 11 people were killed in insurgent attacks across Baghdad. Six of the fatalities occurred when a police patrol was hit by a roadside bomb. In a separate incident, insurgents fired on a car, killing its three occupants, and a mortar shell struck a building in an eastern district, killing two people.
