COUNCIL, Idaho (AP) — A western Idaho wildfire near the border of Washington state and Oregon has forced area evacuations and destroyed one building.

The flames just north of Council, Idaho, first erupted Thursday and is believed to be caused by human action.

As of Saturday morning, the uncontained wildfire is now 23 square miles (60 square kilometers).

It spread overnight into Saturday, forcing evacuations in the Cottonwood Road, south Exeter Lane and Cool Creek Loop areas.

The U.S. Forest Service says one structure has been lost from wildfire damage but it's not immediately known what type of building it was.
