A gunman who dressed as a policeman killed at least 16 people, including a female police officer, in the province of Nova Scotia, Canadian police say.
The 12-hour rampage ended in a car chase. The attacker is also dead.
Residents in the rural town of Portapique had been advised to lock themselves indoors after the attack began on Saturday.
Police earlier said the suspect was driving what appeared to be a police car.
The gunman shot people in several locations across Nova Scotia which meant authorities were still trying to establish the final death toll, police said on Sunday.
The police warned that there may be more victims.
Royal Canadian Mounted Police Constable (RCMP) Heidi Stevenson, who had served in the force for 23 years, was among those killed.
“Heidi answered the call of duty and lost her life while protecting those she served,” Nova Scotia RCMP Commanding Officer, Assistant Commissioner Lee Bergerman said in a Facebook post.
“Two children have lost their mother and a husband his wife. Parents lost their daughter and countless others lost an incredible friend and colleague,” Commissioner Bergerman said.
RCMP Commissioner Brenda Lucki said she believed the gunman had an initial “motivation” at the beginning that “turned to randomness”, according to CBC News.
Canadian Prime Minister Justin Trudeau described it as “a terrible situation” and Nova Scotia Premier Stephen McNeil told reporters “this is one of the most senseless acts of violence in our province’s history.”
