People were killed and injured in a serious incident that resulted in a fire on one of Canada's busiest military bases in Alberta, Defense Minister David McGuinty said on Saturday.
"I'm saddened to share that there have been both fatalities and injuries as a result of an incident" at Canadian Forces Base Wainwright, McGuinty told reporters in Ottawa.
He did not say how many people were killed or injured, or what caused the "tragic" situation at the base in the east-central part of the province, about 210 km (130 miles) east of Edmonton.
A major fire was still burning on Saturday evening, he said, adding: "I cannot recall an incident like this in recent memory."
The Canadian military and the Royal Canadian Mounted Police are investigating the incident, McGuinty said.
