Iraqi police say a car bomb has exploded in eastern Baghdad, killing at least 66 people and wounding more than 100 others.
Authorities say the blast occurred early Saturday in a crowded market in the Shi'ite district of Sadr City.
In a separate incident, Iraqi officials say gunmen kidnapped a Sunni female member of parliament and seven of her bodyguards Saturday in Baghdad. The victim, Taiseer al-Mashhadani, is a member of the Iraqi Accordance Front, the largest parliamentary bloc of the Sunni minority community.
Officials say gunmen ambushed Mashhadani's convoy as it passed through a Shi'ite neighborhood in northern Baghdad.
It is unclear who is responsible for the kidnapping.
