Provinces in Canada have been put on dangerous persons alert after multiple people were stabbed in the James Smith Cree Nation and Weldon, Saskatchewan.

At least 10 people were killed in 13 locations, RCMP said in a press conference and 15 others were hospitalized.

“There could be more injured,” Rhonda Blackmore, commanding officer of the Saskatchewan RCMP, said. “We are currently actively looking for it, dedicating maximum resources to this.”

Two suspects, identified as Damien Sanderson and Myles Sanderson, are reportedly on the run. Regina Police told local media that the duo may be traveling in the Arcola Avenue area.

“As the suspects are at large, we have also asked for the alert to be extended to Manitoba and Alberta,” RCMP said in a news release just after noon Sunday.

Police described Damien as 5ft 7in and 155lb, and Myles as 6ft 1in and 200lb. Both were said to have black hair and brown eyes.

In an alert, RCMP said that the two suspects are likely in a black Nissan Rogue with Saskatchewan licence plate 119 MPI.

Authorities said that they have “deployed additional resources for public safety throughout the city, including the football game at Mosaic Stadium.”

The incidents took place as the Saskatchewan Roughriders is preparing to take on the Winnipeg Blue Bombers in the annual Labour Day Classic matchup.

“The Club operates a centralized command centre on game day that allows immediate connection to local emergency services and the ability receive up to the minute information when any sort of emergency occurs,” a statement from the Roughriders read.

“In every situation, the Club works hard to provide the safest and most enjoyable game day possible.”

The Saskatchewan health authority said patients were being treated at several sites.

“A call for additional staff was issued to respond to the influx of casualties,” a spokesperson, Anne Linemann, said in an email, according to the Guardian.
