FAIRVIEW, Utah (AP) — Authorities in central Utah say a wildfire in Sanpete County has burned an estimated 1.5 square miles (4 sq. kilometers), destroyed at least two structures and forced the evacuation of approximately 350 people while threatening 150 homes.

It isn't yet known what caused the fire near Milburn, Fairview and Indianola to start Monday and there's no report on a containment percentage.

The fire is threatening watersheds, utilities and other infrastructure in the area.

The Sheriff's Office says the Red Cross is helping officials set up evacuation centers.
