A suicide car bomber blew attacked a convoy of foreign troops in southern Afghanistan on Monday, killing two Canadian soldiers and an Afghan civilian, police said. The attacker drove his car up to the convoy and then detonated the bomb, said Kandahar provincial police chief Ismatullah Alizai. Another civilian was injured, and some 15 camels who were with a group of nomads were killed, he said. Maj. Luke Knittig, a spokesman for NATO's International Security Assistance Force, confirmed that two ISAF soldiers were killed, but he didn't release their nationalities. He said the soldiers were helping assist reconstruction projects in the Panjwayi and Zhari districts outside Kandahar. The areas have been the scene of heavy clashes over the last several months.
