BOISE, Idaho (AP) — A wildfire burning through grass and sagebrush in the Boise foothills destroyed a house and an outbuilding Thursday morning but no injuries have been reported.

Officials say the fire started at about midnight and consumed about 1,000 acres but crews using bulldozers built a fire line to protect a subdivision.

Fire spokesman Brandon Hampton says aircraft started dropping retardant shortly after sunrise and the active part of the blaze has been stopped.

He says crews are transitioning to mopping up.

He says several thousand homes were threatened and voluntary evacuations were in place but few residents utilized a shelter that had been set up.

About 70 federal firefighters and 70 local firefighters from area cities with 11 fire engines are battling the blaze.
