Afghanistan ? A suicide car bomber apparently targeting a Canadian military convoy detonated a vehicle packed with explosives Friday in southern Afghanistan, killing himself and three civilians, police said.

The attack, 15 miles north of the city of Kandahar, killed the bomber and three nearby civilians, said Zmarai Khan, a district police chief.

Dawood Ahmadi, a spokesman for the governor of Kandahar, said a convoy of Canadian military vehicles had passed near the suicide car bomber before the explosion and that those vehicles were the likely target.

A coalition military spokes-man couldn’t immediately be reached for comment.
