At least five people were killed in two separate attacks in Baghdad Thursday, one targeting a local member of the prime minister's party, police said. Three people were killed and 11 injured when a bomb planted at the house of a local member of the Dawa party detonated at dawn in a Shi'ite-dominated area of southeastern Baghdad, a police official said on condition of anonymity as he was not authorized to speak to the media. The party member, who police did not name, was not at home when the bomb exploded. Among the dead was a man, a 13-year-old boy and a woman who was in a house next door. In the Shi'ite-dominated New Baghdad neighborhood in the eastern party of the city, two street sweepers were killed when a roadside bomb exploded around 7 a.m., police said. At least four others were wounded in the incident.
