A school shooting in Canada’s province of British Columbia has left eight people dead, including a shooter, while dozens are injured.

Two more people found dead at a home believed to be connected to the incident, Canadian authorities said on Tuesday.

The Royal Canadian Mounted Police (RCMP) says a suspect was found dead with what’s believed to be a self-inflicted injury and more than 25 people are injured, including two who are in a life-threatening condition.

“As part of the initial response to the active shooting, police entered the school to locate the threat. During the search, officers located multiple victims. An individual believed to be the shooter was also found deceased with what appears to be a self-inflicted injury,” RCMP said in a statement.

“Six additional individuals, not including the suspect, have been located deceased inside the school.

“Two victims have been airlifted to hospital with serious or life-threatening injuries. A third victim died while being transported to hospital.”

Police earlier said officers were working to determine whether a second suspect was involved.

They are asking residents of the town of Tumbler Ridge, which has a population of about 2400 people, to stay inside as additional police resources are being deployed to the area from neighbouring areas.

The Peace River South School District said there was a the “lockdown and secure and hold” at both the secondary school and the Tumbler Ridge Elementary school on Tuesday.

Larry Neufeld, the member of the legislature for Peace River South, told reporters that an “excess” of resources, including RCMP and ambulance support, had been sent to the community.

He said he didn’t want to release any more information over concerns that it might jeopardise the safety of the ongoing operation.

He urged those in the community to stay where they are.

“We do understand that a few folks are out looking for loved ones, and again, please, please go back to your homes and shelter in place and allow the amazing people of the RCMP to make this community, this beautiful community, safe again,” he said.

Tumbler Ridge is more than 1000km north of Vancouver, near the border with Alberta.

The provincial government website lists Tumbler Ridge Secondary School as having 175 students from Grades 7 to 12.

School shootings are rare in Canada.
