Insurgents using roadside bombs and drive-by shootings killed one Iraqi and wounded 10 others Saturday, the Associated Press reported. Elsewhere, bomb blasts killed six Marines as the U.S. military announced on Friday that it had completed a major sweep in western Iraq aimed at suppressing militants before the constitutional vote. The military said 50 insurgents were killed in the six-day Iron Fist offensive, launched Oct. 1 in towns near the Syrian border and completed Thursday.
