A suicide car bomber targeted a NATO convoy in southern Afghanistan Sunday, apparently killing three civilians and wounding three soldiers, officials said. Soldiers opened fire after the blast, wounding at least a half dozen Afghans, witnesses and a doctor said. The explosion damaged a NATO armored vehicle and scattered pieces of the car bomb over a wide area in Kandahar city, according to an Associated Press reporter at the scene. Three NATO soldiers were wounded, said Squadron Leader Jason Chalk, an alliance spokesman in Kandahar. Soldiers opened fire after the bombing, hitting people in their cars, the AP reporter said.
