At least nine people, including seven at a secondary school, were killed in a mass shooting event at a remote part of western Canada Tuesday.

The killings occurred in Tumbler Ridge, British Columbia, a picturesque mountain valley town in the foothills of the Rockies.

A total of 27 people were wounded, including two with serious injuries and 25 others who suffered non-life-threatening injuries, the Royal Canadian Mounted Police said in a statement.

Canadian media have reported that the shooter was female, but the RCMP declined to provide any details on the suspect's identity in a press conference Tuesday.

Police said an alert was issued about an active shooter at Tumbler Ridge Secondary School Tuesday afternoon.
