Five U.S. soldiers were killed by roadside bombs in two separate incidents in Baghdad, the U.S. military said Sunday. In the first attack Saturday around 1:40 p.m., a patrol hit a roadside bomb in the southern Dora neighborhood, killing a soldier from Task Force Baghdad, a statement said. Two others were wounded in that incident. Later that evening, around 11 p.m., four Task Force Baghdad soldiers were killed when a roadside bomb exploded in southwestern Baghdad. The names of all the soldiers killed are being withheld pending notification of next of kin, The Associated Press reported.
