(CNN) -- Four Canadian soldiers were killed and another eight wounded in separate bomb attacks in southern Afghanistan early Friday, Canada's Defense Ministry reported.
The first of the two attacks took place when a roadside bomb struck a foot patrol west of Kandahar about 6:45 a.m. Friday (2:15 a.m. GMT), said Capt. Isabelle Riche, a ministry spokeswoman in Ottawa. Two soldiers were killed and five wounded in that blast, she said.
The second took place about two hours later, when two more soldiers died and three others were wounded when their vehicle was hit by a roadside bomb in the Shah-e-kot valley in Afghanistan's southeast, Riche said.
Canada has more than 2,800 troops in Afghanistan, where a U.S.-led coalition has been fighting since the 2001 al Qaeda attacks on New York and Washington. Friday's attacks bring the country's death toll in the seven-year-old war to 116.
