With a thunderous rumble and cloud of dust and smoke, a suicide car bomb brought down a section of highway bridge south of Baghdad, killing three U.S. soldiers and wounding six from a checkpoint guarding the crossing and blocking traffic on Iraq's main north-south artery. The U.S. military said engineers were being dispatched with bulldozers and other heavy equipment to clear the highway, which was partially blocked by debris from the overpass. An Iraqi interpreter also was wounded in the attack, according to the statement, quoted by the Associated Press.
