Six people were killed and 22 injured by car bomb explosion in outdoor market in Southern Baghdad Tuesday, police said.
The deadly blast occurred about 10 a.m. in the Shiite-dominated neighborhood of Amil, damaging a nearby medical center and setting cars on fire, police said.
Sunni politicians have expressed fears in recent weeks that the neighborhood was witnessing a resumption of sectarian cleansing by Shiite militiamen.
Earlier, in the nearby Khadra neighborhood, gunmen in two cars ambushed a civilian car carrying three plainclothes police officers from the major crimes unit, killing two and wounding the third, police said.
Police and other Iraqi security officers have been targeted by insurgents, who accuse them of collaborating with U.S.-led forces in the country.
