Iraq suicide blast kills dozens in Baghdad BAGHDAD - A suicide bomber detonated an explosives-packed car near a funeral procession in southeastern Baghdad on Friday, killing at least 28 people in the latest brazen attack since the U.S. troop withdrawal, officials said. Police officials said the blast occurred at 11:00 a.m. in the predominantly Shiite neighborhood of Zafaraniyah, where mourners had gathered for the funeral of a person killed the day before. They said 61 people were wounded in the attack. Hospital officials confirmed the death toll. All officials spoke on condition of anonymity because they were not authorized to release the information. Iraq eyes legal action over deadly U.S. raid Al Qaeda in Iraq: U.S. pulled out to save money Marine gets no jail time for Haditha killings At least 200 people have been killed in a wave of attacks by suspected insurgents since the beginning of the year, raising concerns that the surge in violence and an escalating political crisis might deteriorate into a civil war, just weeks after the U.S. military withdrawal. Most of the dead in the wave of attacks have been Shiite pilgrims and members of the Iraqi security forces. Since the United States completed its pullout last month, militant groups - mainly al Qaeda in Iraq - have stepped up attacks targeting the country's majority Shiites to undermine confidence in the Shiite-led government and its efforts to protect people without American backup. There was no immediate claim of responsibility for Friday's attack. On Thursday, 17 people died in bombings around the country, including seven people in attacks on Baghdad's s two predominantly Sunni districts, suggesting that Shiite militants could be retaliating amid fears of a reignited sectarian conflict in the war-ravaged country.
