U.S. and British forces made significant progress in their advance toward Baghdad on Saturday, capturing key southern Iraqi cities and oil facilities with limited casualties. However, a fierce tank battle and cruise missile strikes caused concern. Forces crossed a bridge over the Euphrates River and were over halfway to Baghdad. Meanwhile, a U.S. soldier was detained after grenade attacks at a base in Kuwait killed one soldier and injured 16. Accidental deaths also continued, as two British helicopters collided killing 7.
