OTTAWA, Feb. 10 (Xinhua) -- At least 10 people, including the suspected gunman, were killed in a shooting at a school in Western Canada on Tuesday, local police said.

The Royal Canadian Mounted Police (RCMP) said multiple others injured in the shooting were receiving medical treatment.

Six people were found dead inside a local high school in Tumbler Ridge, British Columbia province, another victim died while being transported to the hospital, and two additional bodies were discovered at a nearby residence believed to be connected to the case, according to the police.

The RCMP said that the shooter was found dead inside the school from a "self-inflicted injury."
