At least seven people have died and dozens are injured following an explosion and subsequent fire at a Canadian military base in the province of Alberta, according to Canadian media reports. The explosion reportedly occurred during live-fire training, potentially after a gas pipeline or well was hit. Authorities have confirmed the incident resulted in fatalities but have not yet released detailed information. The cause of the explosion is currently under investigation, with initial reports suggesting a connection to the training exercise. Emergency services are continuing to work at the scene in Alberta. The full extent of the damage and the number of injured are still being assessed. This represents a significant loss for the Canadian military and a developing situation requiring further investigation.
