led forces and Iraqis working for them. An American soldier was killed and another wounded when their convoy was attacked west of Baghdad and a car bomb killed another U.S. soldier and wounded four in western Baghdad. A suicide bomber drove into a U.S. convoy on the Baghdad airport road in an attack also claimed by Zarqawi's group. U.S. troops sealed off the scene of the attack, but a U.S. military spokesman said he had no information about it. The bodies of three Iraqi translators for U.S. forces were found in Tikrit, north of Baghdad, police said. In Falluja, residents said there was heavy fighting on the eastern and northern outskirts of the city and, for the first time, on the western edge fronting the Euphrates river after intense overnight air strikes and artillery shelling. The U.S. military says 1,000 to 6,000 fighters, including some Zarqawi loyalists are holed up in Falluja. U.S. attacks have killed dozens of guerrillas but have failed to scare them away, a senior Marine commander said. --More 0124 Local Time 2224 GMT
