U.S. TROOPS SHOT A SUICIDE CAR BOMBER IN AFGHANISTAN ON WEDNESDAY AS HE TRIED TO RAM HIS VEHICLE INTO THEIR CONVOY, POLICE SAID. THE CAR BOMB EXPLODED BUT IT WAS NOT KNOWN IF ANY U.S. TROOPS WERE HURT, REUTERS REPORTED. THE ATTACK, ON THE OUTSKIRTS OF THE EASTERN CITY OF JALALABAD, CAME AS THE COMMANDER OF U.S. FORCES IN AFGHANISTAN MET AFGHAN AND PAKISTANI COMMANDERS FOR SECURITY TALKS AFTER A SURGE IN VIOLENCE ON BOTH SIDES OF THEIR BORDER. JALALABAD POLICE SPOKESMAN ABDUL GHAFOUR SAID THE CAR BOMB BLEW UP SECONDS AFTER U.S. TROOPS SHOT THE DRIVER DEAD ON A MAIN ROAD LEADING TO THE KHYBER PASS AND PAKISTAN. A U.S. MILITARY SPOKESWOMAN SAID SHE HAD NO IMMEDIATE INFORMATION ABOUT THE INCIDENT.
