The fire was about 20 acres and some 240 firefighters were at the scene to combat the flames, Los Angeles County Fire Department Inspector David Michael told Newsweek.

"We do have reports of structures threatened, but we don't have an amount of structures yet," Michael said.

There had not yet been any word on evacuations in the area.
