Police received the first report of a stabbing on the James Smith Cree Nation at 5:40 am local time (6:30 am ET) on Sunday morning, and within minutes several additional calls came in to will report other stabbings throughout the community, police said.
Within hours, the situation turned into a mass stabbing event with at least 25 victims, 10 of whom died, police said.
Three helicopters from STARS Air Ambulance were dispatched to the James Smith Cree Nation during the attack, company spokesman Mark Oddan told CNN. The first crew to arrive jumped to triage the victims and the second aircraft brought a medic to assist with triage and lead the emergency response, he said.
Helicopter crews took some victims to Royal University Hospital in Saskatoon and several other patients were taken to local hospitals by ground ambulances, Oddan said. He could not provide details on the patients or their conditions.
Several dangerous person alerts were issued by police in the morning, extending across the province of Saskatchewan and into neighboring Manitoba and Alberta.
Canadian Minister of Public Safety Marco Mendicino asked residents to shelter.
“To everyone in Saskatchewan, especially those near the James Smith Cree First Nation area, please shelter in place and stay safe,” he tweeted.
Authorities have identified 13 separate scenes where the attacks took place.
Additional victims may have been injured and taken themselves to the hospital, police said, urging potential victims to contact law enforcement.
“Our thoughts are with the many victims who died and were injured, their families, friends and communities. What happened in our province today is horrific,” Assistant Commissioner of the Royal Canadian Mounted Police Rhonda Blackmore said.
