Major fire at Canada military base leaves four dead, dozens injured

"There was a multitude of ordnance moving through the Wainwright training area," he said, including a grenade launcher, grenades, small arms and ammunition.A grass fire ignited about 1km (0.6 miles) away, with the cause currently under investigation, and moved toward the attack range."What I would say is there was multiple training activities happening throughout the training area at the time," he said. "Uncommonly strong winds caused the fire to spread rapidly and shift direction towards the range administrative area."Cannon fire had been heard coming from the base on Saturday before it suddenly stopped, Mayor Pugh told the BBC, noting it's not uncommon to hear cannons being fired there.News then came through that local emergency services had been deployed to an "all hands on deck" situation.Carney said military and emergency crews fought the flames throughout the night in "some of the worst conditions imaginable". The people who were hurt were on the attack range and included reservists and soldiers from the Princess Patricia's Canadian Light Infantry, officials said.In a statement early on Sunday, the Canadian Armed Forces said that "while the incident remains under investigation, at this time, there are no indications that it was the result of any terrorist activity".
