The stabbings happened as fans descended nearby for a sold-out bank holiday Canadian Football League game.
Ten people have been killed and at least 15 others injured after stabbings in the Saskatchewan province of Canada.
The attacks happened at multiple locations, with police investigating 13 crime scenes, the Royal Canadian Mounted Police in Saskatchewan said.
Officers are hunting for two suspects, Damien Sanderson and Myles Sanderson, who it is believed are travelling in a black Nissan Rogue.
Some of the victims appeared to have been targeted, while others were attacked randomly, police say, adding there may be additional injured victims who transported themselves to various hospitals.
Canadian Prime Minister Justin Trudeau described the incidents as “horrific and heartbreaking” while the province’s premier, Scott Moe, tweeted he had no words to “adequately describe the pain and loss caused by this senseless violence”.
I also want to thank the RCMP and other police services for the efforts they are making to apprehend the attackers and protect the public, and thank all the first responders and health care professionals who are treating numerous victims.
