LOS ANGELES (Reuters) - An evacuation order was lifted on Monday at the edge of a national forest in Southern California, after a wildfire threatening dozens of homes in the path of the flames.

The so-called Rose Fire, which broke near foothill communities east of the Cleveland National Forest in mid-afternoon, had charred some 150 acres (61 hectares) within several hours, according to the Riverside Fire Department.

The blaze was zero-percent contained at 8 p.m., as local television showed images of the flames bearing down on several homes. There were no immediate reports of injuries or structures destroyed.

Fire officials lifted all evacuation orders at about 8 p.m. local time.

More than 200 firefighters were deployed to battle the flames, assisted by three helicopters and six fixed-wing air tankers.

Investigators determined that the fire was caused accidentally by equipment, the Riverside Fire Department said.
