PORTAPIQUE, Nova Scotia—A gunman in the Canadian province of Nova Scotia killed more than 10 people, including a policewoman, during a 12-hour rampage, authorities said on Sunday, in the worst act of mass murder the country has seen in 30 years.
The Royal Canadian Mounted Police said 51-year-old Gabriel Wortman—who had disguised his car to look like a police cruiser—shot people in several locations across the Atlantic province. Authorities said they were still trying to establish a final death toll.
