Saskatchewan RCMP said an officer has shot and killed a man on the George Gordon First Nation.

Mounties said officers responded to a man armed with a rifle and making threats on the First Nation Tuesday afternoon.

However, during the incident officers shot the man, injuring him.

Medical aid was provided, but the unidentified man would later be pronounced deceased by EMS.

The RCMP have requested the Weyburn Police Department conduct an external investigation.

The Ministry of Justice will appoint independent and First Nations observers.

The identity of the officers involved are not being released.
