U.S. officials say four Americans have been killed in an explosion at a local council building in Baghdad's Shiite Sadr City district.
Iraqi police officials say at least six Iraqi civilians also were killed and 10 others wounded in today's blast, which apparently was targeting Americans visiting the building.
The U.S. military and the embassy say two American soldiers and two American government employees were among the dead.
An embassy spokeswoman says the government employees were civilians with the State Department and the Defense Department.
