Kandahar, Afghanistan A roadside bomb killed four Canadian soldiers Saturday in the deadliest attack on that nation's troops since they deployed in Afghanistan four years ago, and commanders blamed loyalists of the former Taliban regime.
The blast came as Afghan President Hamid Karzai said "foreigners" are fomenting his country's insurgency.
He didn't name any countries or groups.
Canadian officers said the bomb destroyed one of four armored vehicles in a convoy and killed its four occupants in Gomboth, a village about 25 miles north of the southern city of Kandahar, a former Taliban stronghold.
"We are pretty confident that it was the Taliban and we knew coming in here that they would be targeting us," Maj. Quentin Innis told The Associated Press.
A 2,200-soldier Canadian contingent moved into southern Afghanistan to relieve U.S. troops.
Canada has had forces in the country since the U.S.-led offensive that toppled the Taliban at the end of 2001 and a total of at least 16 Canadians have been killed.
There was no immediate claim of responsibility for the bombing, but Taliban militants have vowed to step up attacks on coalition and Afghan forces.
