Four American soldiers were wounded in Afghanistan's southern province of Kandahar on Friday when their convoy was attacked with a car bomb, a senior police official said. The convoy was heading towards Kandahar city from a nearby air base when a car filled with explosives blew up, said General Salim Khan. "American forces have cordoned off the site of the blast and are carrying out an investigation. It seems that explosive materials were packed in a car and it went off when the convoy was passing by," Khan said. He said earlier that a car filled with exlosives had collided with the convoy. The U.S. military in Kabul said it did not know of the incident. A U.S.-led force of some 20,000 soldiers in Afghanistan is fighting an insurgency led by remnants of the ousted Taliban who oppose foreign and Afghan government troops and have vowed to disrupt elections scheduled for October and April.
