RCMP say an officer was responding to a mass stabbing on the Hollow Water First Nation in Manitoba, about 200 kilometres northeast of Winnipeg, when her cruiser crashed with a stolen vehicle driven by the suspect in the attack.

Supt. Rob Lasson says the suspect died at the scene of the crash, and the officer was taken to hospital with critical injuries but is expected to recover.

Manitoba Premier Wab Kinew says the officer "stopped a man on a rampage."

RCMP identified the attacker as 26-year-old man and say he killed his 18-year-old sister.

Seven others were found injured in two different homes in the community and are in hospital.

Mounties say officers continue to investigate and are going from house to house making sure there are no other victims.

Health officials said two victims were airlifted to Winnipeg, while others were taken by ground ambulance.

RCMP described the attack as a "senseless act of violence"

They said there was no longer a risk to public safety, but officers were to remain in the community as well as on a highway to the south near Black River First Nation.

A code orange, which means a sudden influx of patients, had been declared at the largest hospital in Winnipeg, although it was lifted a few hours later.

"Our officers are gathering information to determine what exactly occurred this morning and we will be providing a more detailed update early this afternoon," RCMP said in a news release.

The Anishinaabe community of roughly 530 people is situated along the east shore of Lake Winnipeg.

The attack comes three years to the day after a mass stabbing on the James Smith Cree Nation in Saskatchewan, which left 11 people dead and 17 injured.

Premier Scott Moe saddened by attack, falling on anniversary of JSCN mass stabbing

In a social media post on X, Premier Scott Moe said he was troubled and saddened to hear of the attack in Manitoba.

"My thoughts are with the family and friends of the victims of this senseless attack," he said.

He said the attack comes at a difficult time, lining up with the three-year anniversary of the mass stabbing on James Smith Cree Nation.

"So may we pause to honour the lives lost, stand with the families who continue to grieve, and reflect on the path of healing that continues for so many," he said.
