At least 10 people were killed, and 15 others were stabbed in Canada's Central Saskatchewan province attacks. The attackers fled. A search has been announced.
The victims were found in 13 different locations, including the Canadian Indian community of James Smith and the village of Weldon.
Police have named the suspects in the attacks Damien Sanderson, 31, and Miles Anderson, 30. It is not known whether they are relatives. According to the police statement, they are armed and dangerous.
They were last seen on Sunday afternoon in the state capital of Regina, about 280 km south of Weldon.
Canadian Prime Minister Justin Trudeau called the attacks "horrific and heartbreaking." "I think about those who lost loved ones and those who were injured."
