A quickly growing wildfire west of Prince George, B.C., has prompted a state of emergency and evacuation orders for some homes.

The B.C. Wildfire Service says it was notified of a wildfire burning near Fraser Lake and Lejac, along Highway 16 around 3 p.m. PT Saturday.

At 8:30 p.m. the fire had grown to 100 hectares in size, and by late Saturday night it had reached 260 hectares.

Around 20 firefighters are working to contain the blaze, which is currently described as being out of control and most likely human-caused. The service also used air tankers to drop fire retardant on the flames.
