Coalition forces pounded Baghdad in the first daylight air raids of the war. American forces have progressed 150 miles into Iraq, halfway to Baghdad, and American ships and warplanes have launched hundreds more cruise missiles and precision weapons, Pentagon officials said Saturday. In Kuwait, a command tent of the 101st Airborne Division was attached with grenades at a camp. A U.S. soldier in the division was being questioned; resentment was the suspected motive. U.S. and British forces, meanwhile, tightened the noose around Iraq's second-largest city, Basra, taking its airport and a bridge. President Saddam Hussein's forces resisted with artillery and small-arms fire. Military leaders don't plan to storm and destroy the city, but hope to get the Iraqi's to surrender.
