Multiple explosions have rocked a western district of Baghdad, killing at least 41 people and wounding scores of others.
Hospital officials in the Iraqi capital say many of the dead and wounded are children hit by shrapnel.
The apparently coordinated explosions occurred this (Thursday) afternoon, as a U.S. military convoy passed the scene of a ceremony to open a new water and sewage treatment plant.
Elsewhere, four Iraqis were killed and 16 others wounded in a car bombing in the northern town of Tal Afar. The Associated Press says the bombing targeted a local police chief, who survived the blast.
Earlier, a suicide car bomb blast killed one U.S. soldier and two Iraqi policemen near the Abu Ghraib prison just outside the capital.
Separately, the U.S military says one coalition soldier was killed and seven others wounded in a rocket attack on a base outside Baghdad.
