Four service members killed in massive fire at CFB Wainwright

Officials are calling it one of the worst tragedies for Canada's military on domestic soil during peacetime. A violent, fast-moving fire tore through CFB Wainwright in Alberta. Starting in a training area, setting off a grass fire, the flames spreading quickly beyond the base. Four service members are confirmed dead, and dozens of other people are injured. The cause is under active investigation - while the province, and the country, rally to offer medical help and support.
