A suicide bomber on a motorcycle attacked a Canadian military convoy in Afghanistan on Tuesday, but no soldiers were injured.

The bomber slammed his motorcycle into the second vehicle in a Canadian convoy as it enteredwestern Kandahar City from the outskirts, witnesses told CBC News.

More than 2,000 Canadian soldiers are stationed in southern Afghanistan, based mainly in Kandahar.

The soldiers anticipated the bombing and were able to get out of their G-Wagon before it caught fire, said CBC reporter Stephen Puddicombe from Kandahar.

The lightly armoured jeep-like vehicle hasbeen criticizedfor failing to provide enough protection during dangerous patrols outside of the main base.

Three employees of the Kandahar Development Agency were injured in the attack.

Tuesday's suicide bombing is thethird in four days in Afghanistan.

Twelve people were killed on Saturday when a suicide bomber blew himself up nearAfghanistan's Interior Ministry in Kabul, while six people were injured Monday when a suicide bomber blew himself up near a NATO convoy in the capital.

Canadian troopsare part of a NATO-led mission in Afghanistan thatincludes about 20,000 alliance troops and 20,000 U.S. soldiers.

Canada, the U.K., the U.S. and the Netherlands provide the bulk of troops in the volatile southern region, a stronghold of the former Taliban government.

Thirty-seven Canadian soldiers and one diplomat have been killed since the mission started four years ago.

The body of the latest Canadian soldier to die is expected to return to Canada on Tuesday. Pte. Josh Klukie, 23, was killed on Friday when he stepped on an anti-tank mine while on foot patrol near Kandahar.
