60 South Korean contract engineers and technicians working for the U.S. to restore Iraq’s power grid have decided to leave Iraq a week after two of their colleagues were killed. The Washington Post reports this marks the largest withdrawal of contractors over security issues. Their decision came as the chief U.S. military commander in Iraq, Lt. Gen. Ricardo Sanchez warned that the occupying forces would come under increasing attacks in the lead-up to national elections in Iraq. And in Mosul, one U.S. soldier was killed Sunday when a bomb blew up under an Army humvee.
