EXECUTIVE SUMMARY
Four service members died and 39 others sustained injuries following a massive explosion and subsequent fire at a Canadian military training facility.
"I cannot recall an incident like this in recent memory," one official said.
Multiple people were killed and dozens more were injured when an explosion erupted at a Canadian military base, according to authorities.
The deadly blast occurred on Saturday afternoon at the Canadian Forces Base (CFB) Wainwright in Alberta province, igniting a massive fire that was fanned by high winds and spread from the sprawling military facility into the surrounding rural area, Canadian officials said.
