Iraqi police say a car bomb has exploded in eastern Baghdad, killing at least 66 people and wounding about 100 others.
Authorities say the blast occurred early Saturday in a crowded market in the Shi'ite district of Sadr City.
Separately, Iraqi officials say gunmen kidnapped a Sunni female member of parliament and seven of her bodyguards today in Baghdad. A spokesman for the parliament speaker's office says the victim is Taiseer al-Mashhadani, a member of the Iraqi Accordance Front, the largest parliamentary bloc of the Sunni minority community.
No other details were immediately available.
The Iraqi government has imposed a security clampdown on the capital for the past three weeks.
Meanwhile, the U.S. military said Friday it is investigating at least three soldiers accused of raping a woman and killing her and three family members.
Authorities said the Iraqis were killed in March at their home in Mahmoudiya, south of Baghdad.
The investigation is the latest in a series of probes of U.S. troops suspected of killing civilians in Iraq.
