An 18-year-old woman has died and seven other people have been injured in a mass stabbing at a remote indigenous community in Canada, police say.

The suspect also died in Thursday's attack at a First Nations community in the province of Manitoba, according to the Royal Canadian Mounted Police (RCMP).

The incident took place in Hollow Water First Nation, about 200km (124 miles) north-east of the city of Winnipeg.

Police said the suspect was fleeing the scene when he died in a vehicle collision with an RCMP policewoman, who was critically injured.

The family of one victim said he was awoken in the middle of the night and was stabbed in the torso.

Investigators indicated that the woman killed was the sister of the suspect, and that he was previously known to police.

In a news conference, the federal police force stated that officers were on-site at the Hollow Water First Nation, ensuring the community's safety and confirming there are no additional victims.

Our sincere condolences to everyone within the community of Hollow Water First Nation and to all affected by this senseless act of violence, the RCMP said.

Police responded to the community at 03:45 local time on Thursday, after a tribal security officer reported an assault had taken place 30 minutes earlier.

When police arrived, they were alerted to a second crime scene where stabbing victims were located at both locations.

RCMP major crimes unit Supt Rob Lasson declined to share any suspected motive for the attack but noted that all victims were known to each other within the community.

The suspect, Tyrone Simard, 26, fled in a stolen car and appears to have been heading toward Winnipeg when he collided with the police vehicle.

The policewoman, who has not been named, was taken to the hospital with critical but non-life-threatening injuries and is expected to make a full recovery.

Manitoba Premier Wab Kinew praised the police officer, saying: She stopped a man on a rampage.

The Chief of Hollow Water First Nation, Larry Barker, expressed his deep condolences to the families affected by the tragedy, asking the community to support one another.

The Anishinaabe community has a population of a few hundred people and is still processing the implications of this attack.

One of those injured in the attack was identified by family members as Michael Raven. His children reported he was stabbed in the lung by someone who broke into his home while he was asleep.

The attack coincided with the third anniversary of a mass stabbing in James Smith Cree Nation and the nearby village of Weldon, Saskatchewan, which resulted in 11 fatalities and many injuries.
