Canada school shooting: Four killed in Saskatchewan.

Four people have been killed and several injured in shootings in the western Canadian province of Saskatchewan, police say.

They say a male suspect is now in custody and children have been moved to safety after the shootings at La Loche Community School and another location.

Canadian PM Justin Trudeau said earlier that five people had been killed, but this was later corrected.

The school shooting was "every parent's worst nightmare", Mr Trudeau said.

"The community is reeling."

Mr Trudeau, who was speaking in Davos, Switzerland, also praised "the first responders who acted quickly and bravely".

Witnesses at the school described screaming and more than half a dozen shots.

Kevin Janvier, acting mayor of La Loche, said that his 23-year-old daughter Marie, a teacher, was one of the victims at the school.

He also said police had told him that the gunman first shot two of his siblings at home and then made his way to the school.

'Shock and sorrow'

At a news conference, Maureen Levy, a senior officer at the Royal Canadian Mounted Police (RCMP), said: "There's no risk to public safety at this time. This is truly a tragedy."
