At least ten people have been killed and many others injured, after two assailants went on a stabbing spree in multiple locations in a rural area of Saskatchewan province, the Royal Canadian Mounted Police confirmed on Sunday. They warned that the suspects were still at large, and armed and dangerous.

“We have located 10 deceased individuals in 13 locations in the community of James Smith Cree Nation and Weldon, Saskatchewan,” RCMP Assistant Commissioner Rhonda Blackmore said at a press conference on Sunday afternoon.

The police official added that “several additional victims have been injured, 15 of which at this point have been transported to various hospitals,” noting that there “may be additional injured victims who transported themselves to hospital,” and urging them to come forward.

“We believe some of the victims have been targeted, while others have been attacked randomly,” Blackmore added.

A public alert about an incident with “mass casualties” was first issued at 7:12am CT (12:12pm GMT) on Sunday. Saskatchewan authorities identified two male suspects as well as their vehicle, and expanded the emergency warning to the entire province.

“As the suspects are at large, we have also asked for the alert to be extended to Manitoba and Alberta,” even though “at this point in time, we have no indication they travelled to another province,” the RCMP added.

The suspects have been named as Damien Sanderson, 31, and Myles Sanderson, 30, possibly driving a black Nissan Rogue with SK license plate 119 MPI.

As the manhunt continues, authorities are urging the public against leaving secure locations, approaching suspicious strangers or picking up hitchhikers, and to report any suspicious activity to the authorities.
