LAKE ISABELLA, Calif. (AP) - A forest fire in the southern Sierra Nevada has grown to more than 8,100 acres even as firefighters gain ground on the blaze that has destroyed one home.

Fire commanders say aircraft will be important Thursday in keeping the fire from high-risk areas in the region 110 miles north of Los Angeles.

The nearly 13-square-mile fire threatens 250 homes since breaking out Sunday in the Lower Kern River Canyon southwest of Lake Isabella. Portions of the communities of Bodfish and Havila are evacuated. The fire is 65 percent contained.

In northwest Los Angeles County, firefighters have made quick work of a pre-dawn 20-acre brush fire accidentally ignited by a vehicle along Interstate 5. Two-hundred firefighters, three helicopters, a helitanker and two planes responded to the fire.
