Meanwhile Secretary of State Colin Powell landed in Baghdad to mark the one year anniversary. This morning more than 20 Arab journalists walked out of a Powell press conference in Iraq protesting the death of two Iraqi journalists from the Arabic news channel Al-Arabiya who were allegedly killed by the US Thursday. According to the station, one of their cameramen and correspondents witnessed a car accident between a U.S. vehicle and an Iraqi. Fearing a car bombing, they ran from the scene and were shot. The U.S. claimed it killed only one person when he tried to run through a check point. Meanwhile in Northern Iraq three Iraq journalists were killed by gunmen. They had been working for a TV station funded by the U.S.-led coalition.
