Canadian soldiers fired their first shots in self-defence on Thursday since arriving in the volatile southern Afghan province of Kandahar late last month.
Troops were patrolling the streets during the country's Independence Day celebrations when a van tried to overtake their convoy from behind.
A military spokesman has said there were concerns that the driver might be a suicide bomber so a gunner fired four rounds into the vehicle's engine block to disable it.
According to initial reports, no one is believed to have been injured during the incident.
How long before the usual suspects start screaming for our troops to be brought home because somebody might get killed over there?
