Neil Young, Gerard Butler, Miley Cyrus, among those to lose homes in California wildfires

Neil Young, Gerard Butler and Miley Cyrus are among the celebrities whose homes have been destroyed by the deadly wildfires in California that has claimed the lives of at least 31 people and forced hundreds of thousands of residents to flee, US media reports said Monday.

The Woolsey fire is one of three major blazes burning across California. As of Sunday night, the fire had spread to 85,500 acres.

Together with the smaller Hill fire, which spans 4,531 acres, the Woolsey fire has so far destroyed 179 structures, but fire officials say another 57,000 are threatened.

The third fire, Northern California's Camp fire, is the most destructive in state history and one of the deadliest. That blaze virtually burned the town of Paradise to the ground, destroying thousands of homes and structures. Some 228 people are unaccounted for, CNN reported.

Butte County Sheriff Kory Honea on Sunday said the bodies of five people had been found in their burned-out homes and a sixth was found inside a vehicle.

He said that at least 228 people were still unaccounted for, adding that DNA testing equipment was being sent should it be required to help identify victims.

The mayor of Paradise, Jody Jones, said the situation in the town was grim.

"Most of the residential [area] is gone. I would say 90%," she said. "I had an opportunity to go up there and take a look for myself. Just about everyone I know lost their home."
