Teenager charged with four counts of murder over Canada school shootings

Police say a 17-year-old has been charged with four counts of first-degree murder and seven counts of attempted murder in a mass shooting at a school and home in western Canada.

Police said on Saturday the male suspect can't be named under Canada's Youth Criminal Justice Act.

Royal Canadian Mounted Police Superintendent Grant St Germaine says nine people were shot in the school, two fatally. He says seven people wounded in Friday's shooting at the school are hospitalised.

Police say two brothers, 17-year-old Dayne Fountaine and 13-year-old Drayden, were shot dead in a home before the gunman headed to the La Loche Community School.

The suspect was arrested outside the school on Friday afternoon.

The school is in the remote Dene aboriginal community of La Loche in Saskatchewan Province.
