American soldiers fired on two cars at a checkpoint in Fallujah, killing four Iraqis and wounding five others, local residents and Arab satellite television reported Saturday. Residents said the incident occurred about 10 p.m. Friday on the eastern edge of the city. Al-Jazeera television and local residents said the dead included two men and two women and that one of those injured was a child. Meanwhile, Washington has agreed to give the United Nations a bigger political role in overseeing Iraq's transition to democracy, an American official told The AP on Friday. The United States is pushing for a new U.N. resolution to try to get more nations to contribute troops and money to Iraq, but faces stiff opposition from France, Germany and several other Security Council members that want Bush administration to relinquish power quickly and give the United Nations more say in the process. The American official, who requested anonymity, said the United States has agreed to give the international body a bigger role in the election and the political transition to a democracy. "We've promised to turn that process over to the U.N. So I think you've seen the United States move quite a bit," the U.S. official was quoted as saying. **PHOTO CAPTION*** A small Iraqi girl lies in a hospital near the town of Falluja, 50 km west of Baghdad, after being injured by U.S. soldiers in an incident nearby on September 26, 2003.
