Carney says four service members killed in fire at Canadian base

Prime Minister Mark Carney said Sunday that four service members died and dozens were seriously injured after a fire swept through Canadian Forces Base Wainwright in Alberta on Saturday. Defense Minister David McGuinty said the fire began during a "serious incident" and spread beyond the base due to high winds. Carney called it one of the worst peacetime tragedies for Canada's armed forces and ordered flags flown at half-mast. The cause remains under investigation; officials said there is no indication of terrorism.
