Police hunted for two suspects who went on a stabbing spree that killed 10 people and wounded at least 15 others in and around an Indigenous community in central Canada.

The stabbings across 13 crime scenes were among the deadliest mass killings in modern Canadian history and certain to reverberate throughout the country, which is unaccustomed to bouts of mass violence more commonly seen in the United States.

Police responding to emergency calls on Sunday found 10 people dead in the Indigenous community of James Smith Cree Nation and the nearby town of Weldon in Saskatchewan province, Royal Canadian Mounted Police Assistant Commissioner Rhonda Blackmore told a news conference.

“Several additional victims have been injured, 15 of which at this point have been transported to various hospitals,” she said. More victims may made their way to hospitals on their own, she added.

Police named two suspects and provided photos and descriptions but no further details about their motive or the victims.

“It is horrific what has happened in our province today,” Blackmore said. “It appears that some of the victims may have been targeted, and some may be random. So to speak to a motive would be extremely difficult at this point in time.”

A statement by Indigenous leaders indicated the attacks may have been drug related.

“This is the destruction we face when harmful illegal drugs invade our communities,” said Federation of Sovereign Indigenous Nations. The group represents 74 First Nations in Saskatchewan.
