Attacks in Baghdad Kill 13 U.S. Soldiers in 3 Days

Thirteen U.S. soldiers have been killed in Baghdad since Monday, the American military reported, registering the highest three-day death toll for U.S. forces in the capital since the start of the war.

The latest losses -- four soldiers who were killed at 9 a.m. Wednesday by small-arms fire -- are part of a recent spike in violent attacks against U.S. forces that have claimed the lives of at least 24 soldiers and Marines in Iraq since Saturday, the military said.
