More than 30 people were wounded in the bombing at a market in the Sadr City area.
Iraqi police say an earlier suicide truck bombing killed 10 people and wounded more than 40 near a police station in the northern city of Kirkuk.
The U.S. military says two American soldiers have died from wounds sustained in combat in the western province of Anbar.
In other news, a U.S. aid organization says one of its American workers, a woman, and three private security guards were ambushed and killed in Baghdad Wednesday.
A Washington-based official with the National Democratic Institute says the slain security personnel were from Croatia, Hungary and Iraq. He says it is not clear who carried out the attack.
The official says the Institute has no immediate plans to end its work in Iraq, but that the situation will be re-assessed in light of the attack.
The National Democratic Institute is a non-profit organization that is providing training and advice to Iraqi political parties, civil groups and members of parliament.
