A suicide car bomber rammed into a Canadian supply convoy Monday, leaving at least three Afghan civilians dead and one Canadian soldier slightly injured.

The soldier is reportedly in good condition in hospital at Kandahar Airfield.

The bomber died in the blast, which happened around 12:30 p.m. local time at a busy intersection on the outskirts of Kandahar.

At least four Afghan civilians were also wounded in the attack, police officer Abdul Wasai told The Associated Press.

Shrapnel and debris struck some bystanders. The blast blew out the windows of a nearby mosque.

Truck driver Abdul Shakoor, 23, was at an adjacent customs office when the incident occurred.

"Part of it hit my belly," Shakoor told CP as he arrived at the Mirwise Hospital in Kandahar. "I can't hear anything now, but I am thankful to Allah that I am not dead. I am supporting all of my family."

One Afghan civilian claims he was hit by gunfire from the direction of the Canadian convoy in the immediate aftermath of the explosion.

Mohammad Server, 40, a cook at a local police station, said through a translator that he was preparing for prayers when the convoy was attacked.

"I was in the mosque and I was shot there. It is very disgusting," he told The Canadian Press.

A spokesperson for the Canadian military in Kandahar said soldiers fired warning shots after the attack.

"But I'm assured they were well controlled, well aimed and not in fact aimed at any person. There were no injuries reported as a result of Canadian warning shots," she said.

"I'm not saying it's not possible, but knowing what we know about how we operate out there ... it seems very unlikely."

Another suicide attack near a school in Kabul left three Afghans wounded, reported Reuters. Police had been tracking the vehicle. They had surrounded the bomber when he blew himself up.

The school was located on a main road that links the U.S. embassy and the city's airport.

Hayat Khan, a purported Taliban commander, told Reuters by phone that Taliban bombers carried out both attacks.

A total of 42 Canadian soldiers and one diplomat have been killed in Afghanistan since 2002. Currently, about 2,300 Canadian troops are based in southern Afghanistan.

The funeral for Trooper Mark Wilson, killed in a roadside bomb attack over the Thanksgiving weekend near Kandahar, was held in London, Ont. on Monday. About 1,000 gathered inside a church and a few hundred more followed the service by listening to speakers placed outside the church.
