In the latest violence, at least 14 people died when a roadside bomb exploded by their bus just south of Baghdad.
Earlier, reports said explosions hit a market in Baghdad's Shi'ite district of Sadr City, killing several people. The cause of the explosion is unclear.
Some residents accused U.S. forces of shelling the market. Brigadier General Mark Kimmitt, spokesman for the U.S.-led coalition, denied that: "The recent attack in Sadr City, I'm sorry to say, was in fact some mortar rounds that were fired by an organization -- certainly not the [U.S.-led] coalition -- resulting in a total of six killed and 38 wounded today. That was in an area near a coalition base, down by the old cigarette factory."
The U.S. military also said that an attack on a military base north of Baghdad killed five soldiers and wounded six.
Two other U.S. soldiers were reported killed in the southern city of Al-Kut.
In the northern city of Tikrit, a car bomb exploded outside a U.S. military base, killing at least two Iraqi policemen.
