U.S. Convoy Ambushed; Oil Wells Ablaze A U.S. supply convoy is overrun by Iraqi forces near Nasiriyah after an apparent wrong turn. Four of the 16 people in the convoy are found wounded at the scene. The other 12 are believed to be the captured Americans shown on videotape aired by Al-Jazeera television. Meanwhile, it appears fewer oil wells are on fire in southern Iraq than initial reports indicated. Hear NPR's Lynn Neary, NPR's Scott Horsley and NPR's Joe Palca.
