A gunman disguised as a policeman killed at least 16 people, including a female police officer, in the worst mass shooting in Canada’s modern history.
The 12-hour rampage started late on Saturday and ended with a car chase.
Police said the suspect shot people at different locations in Nova Scotia, many of them randomly. He was killed in a confrontation with police.
He was reported to have been driving what looked like a police car.
Canadian Prime Minister Justin Trudeau described the attack as “a terrible situation”.
Nova Scotia Premier Stephen McNeil told reporters this was “one of the most senseless acts of violence in our province’s history”.
