Canadian military base fire: Four deaths confirmed as cause remains under investigation

A fast-moving fire swept through Canadian Forces Base Wainwright in Alberta on Saturday, killing four service members and seriously injuring dozens, Prime Minister Mark Carney said. Authorities have not confirmed the cause; local media reported that a gas main may have been struck during a live-fire exercise. The defence ministry said the cause remains under investigation and that there are no indications of terrorist activity. The deceased have not been identified publicly, but their families have been notified.
