The Canadian military is investigating how two Canadian soldiers were injured Sunday in a traffic accident in Kandahar, Afghanistan.

The accident happened as a military convoy was passing through the southern Afghan city.

The military said one of its light armoured vehicles had its gun turret extended out to the side when a passing vehicle clipped it.

"The force of the collision caused the turret to swing around, hitting two soldiers who were standing up in the vehicle," said CBC reporter Derek Stoffell, who is in Kandahar.

"The soldiers' heads were exposed at the time to help them monitor activity behind the vehicle," he said.

Canadian military spokesperson Capt. Julie Roberge told CBC News the soldiers were given medical attention right away.

Taken for treatment

"The two soldiers were air-evacuated to Kandahar medical facility," she said.

She said one of them would be flown for treatment at the U.S. military hospital in Germany.

"One of the soldiers is in fair condition but he will be taken to the medical facility in Landstuhl, Germany," she said.

"The other soldier is in very good condition, " she said, adding that he is expected to return to duty.

The names or other details of the injured soldiers have not been released.

"Canadian soldiers are now investigating how the accident happened," Stoffel said.

Twelve Canadians have been killed in Afghanistan since 2002 – 11 soldiers and one diplomat.

On March 29, Pte. Robert Costall died while fighting a Taliban assault 110 kilometres northwest of Kandahar.

Costall was the first Canadian soldier to be killed by enemy fire while serving in the country.

There are about 2,200 Canadian soldiers at the base in Kandahar, along with roughly 6,000 other coalition soldiers, including Americans, British, Dutch and French.
