Two Canadian convoys were hit in two separate militant attacks near Kandahar, Afghanistan on Thursday.

No Canadians were hurt in the strikes, but five Afghan civilians were injured in the two explosions, The Canadian Press reported.

Three of the wounded Afghans were children.

One of the attacks involved a suicide bomber in a vehicle, and took place in the Panjwaii region, said Maj. Dale MacEachern, a spokesperson for Task Force Afghanistan.

The other attack involved an improvised explosive device, or IED, and happened in Kandahar City.

Both areas are located in Kandahar province in the south of Afghanistan, where most of the heavy fighting has taken place.

Most of Canada's roughly 2,500 troops -- serving with the International Security Assistance Force -- are stationed in the south of Afghanistan.

Wednesday's attacks came as Gov. Gen. Michaelle Jean paid a surprise visit to Afghanistan, and as NATO launched a large-scale operation to drive Taliban militants out of strongholds in Helmand province.

Operation Achilles, a British-led campaign, involves more than 4,500 NATO troops -- including Canadians -- and nearly 1,000 Afghan National Security Forces.

Since Canadian troops first arrived in Afghanistan in 2002, 45 Canadian soldiers have been killed.

The most recent death occurred on Tuesday when Cpl. Kevin Megeney, of Stellarton, N.S, was killed in his tent at the Kandahar base in a mysterious shooting.

Megeney's body is scheduled to be repatriated on Friday. Military officials have said little about the circumstances of the 25-year-old's death pending the results of an investigation.
