MURRIETA (AP) — Crews are still fighting a stubborn wildfire in rural Riverside County that has burned through 355 acres of heavy vegetation and destroyed one home.

State fire spokeswoman Jody Hagemann says the fire near Murrieta was 90 percent contained Saturday morning.

Firefighters are constructing containment lines and patrolling the edges of the fire area for hot spots.

The fire broke out Wednesday morning when brush was ignited by sparks that were thrown off when mowing equipment became entangled in barbed wire on a road.

That day, wind-whipped flames burned down a large two-story home in Murrieta, about 90 miles east of Los Angeles.

The fire’s acreage has held steady since Thursday.

Ten fire crews and 10 engines are working with aerial water drops to douse flames.
