A car bomb explosion early Tuesday was followed by clashes between U.S. troops and insurgents in the Sunni Triangle city of Ramadi, police and eyewitnesses said. There were no details of the bomb explosion in the city's al-Ziyout area, said Police Capt. Nassir Hassan. Following the blast, U.S. soldiers and rebels exchanged gunfire. An Associated Press photographer saw two dead persons and four wounded Iraqis at the scene of the clashes in this rebel stronghold 113 kilometers (70) miles west of Baghdad.
