A suicide car-bomber attacked a military convoy including US troops in the southern Afghan city of Kandahar yesterday, killing three Afghan civilians, witnesses and a senior official said. The scene of the blast, which struck in the morning rush-hour in the southern city, was cordoned off while the US military denied the coalition convoy had taken a direct hit. âThe car bomb, which killed its driver, detonated on the outskirts of Kandahar against the convoy as it was returning from a nearby forward operating base. There were no US injuries or deaths,â the US military said in a statement. A civilian flat-bed truck was destroyed, it added.The Taleban, Afghanistanâs former rulers who are fighting an insurgency against US-led forces that overthrew them, claimed responsibility for the blast in their former stronghold and said they had killed four US soldiers in the suicide attack. US military spokesman Colonel Jerry OâHara said he had no information on a report by Kandahar governor Assadullah Khalid that three American soldiers had been slightly injured in the attack.
