The body of what is believed to be a 10-year-old girl has been found following a house fire on a northern Saskatchewan First Nation.

On Tuesday at around 1:30 a.m. CST, police and firefighters were dispatched to the home at Pelican Narrows on the Peter Ballantyne Cree Nation.

The occupants of the house were an elderly man and woman. Staying with them was their 10-year-old great-granddaughter, the RCMP said.

The man and woman were able to escape from the burning home and originally believed the girl got out, too.

However, the remains of what is expected to be the young child were located among the debris later in the morning.

An autopsy will be conducted, police said.

The house burned to the ground. The cause is under investigation. The names haven't been released.

Pelican Narrows is about 120 kilometres northwest of Flin Flon, Man.
