The homes of Hollywood superstars were under threat as more than 1,000 firefighters battled the unrelenting inferno near Los Angeles.
Fanned by strong winds, a series of fires which broke out on Monday swept across more than 90 square miles, destroying homes and buildings.
Multi-million-dollar mansions in the upmarket neighbourhood of Bel Air – where A-list celebrities including Jennifer Aniston and Beyonce own homes – were engulfed in flames.
The Los Angeles Fire Department said three firefighters were taken to hospital after suffering injuries tackling the blaze.
On 7 December, President Donald Trump said: “Our thoughts and prayers are with everyone in the path of California’s wildfires.
“I encourage everyone to heed the advice and orders of state officials.
“Thank you to all first responders for your incredible work.”
Production of TV shows, including HBO’s sci-fi drama Westworld, has been halted.
Producers decided to shut down and avoid any danger to actors or crew as they were filming its second season in an area near two fires in Los Angeles County.
One of the worst hit areas was Ventura County, 50 miles northwest of Los Angeles, where 12,000 homes were under threat.
More than 250,000 homes have lost power and highways were closed, while schools cancelled classes in some areas.
