A teenager has pleaded guilty to murdering two people and wounding seven others in a mass shooting at a high school in a remote aboriginal community in western Canada earlier this year.

The 18-year-old, whose name was not released under Canada's Youth Criminal Justice Act, also admitted to killing two brothers in a nearby home in northern Saskatchewan.

The teenager on Friday entered guilty pleas to first-degree murder in the shooting deaths of two teachers at his school in La Loche, Saskatchewan and to second-degree murder in the deaths of two teenage brothers in the remote Dene community on Jan. 22.

Provincial court Judge Janet McIvor said the courts still need to determine if he should be sentenced as a youth or an adult.
