The charred remains of 14 more people have been found in and around a Northern California town overrun by flames from a massive wildfire, officials said on Saturday, raising the death toll to at least 23.

The bodies were recovered in and around Paradise, a mountain community some 90 miles (145 km) north of Sacramento that has been left devastated by the Camp Fire, California Department of Forestry and Fire Protection spokesman Scott Maclean said.

Maclean said no details were immediately available about the circumstances of the deaths and that the victims' badly burned condition would make identification difficult.

The Camp Fire burned down more than 6,700 homes and businesses in Paradise, more structures than any other California wildfire on record, and the death toll, which could still rise, also makes it one of the deadliest.

Only the Griffith Park Fire in 1933 and Tunnel Fire in 1991 have claimed more lives.

Several of the bodies discovered earlier this week were found in or near burned out cars, police have said. The flames descended on Paradise so fast that many people were forced to abandon their vehicles and run for their lives down the sole road through the mountain town.

An additional 35 people have been reported missing and three firefighters have been injured. It was not immediately clear if any of the missing were among those found dead.

As of Saturday afternoon, the Camp Fire had blackened more than 100,000 acres (40,500 hectares) at the edge of the Plumas National Forest. Crews had cut containment lines around about 20 percent of the blaze.

About 500 miles (800 km) to the south, the Woolsey Fire burning in the foothills above Malibu doubled in size overnight, threatening thousands of homes after triggering mandatory evacuation orders for a quarter million people in the posh beach city as well as other communities in Los Angeles and Ventura counties.

The fire has destroyed "a lot of homes," with a full count still under way, and has now charred more than 70,000 acres, Los Angeles County Fire Chief Daryl Osby said.

"Our firefighters have been facing some extreme, tough fire conditions that they said that they've never seen in their lives," Osby said at a news conference.

TWO BODIES FOUND IN MALIBU

He said crews hoped to take advantage of a lull on Saturday in the fierce Santa Ana winds driving the flames, but that gusts could return on Sunday.

All 13,000 residents of Malibu, which is 30 miles west of downtown Los Angeles, were told to get out on Friday.

Two bodies were discovered in the community on Saturday but it was too early to determine if they died from the Woolsey fire or another cause, Los Angeles County Sheriff's Department officials said.

Firefighters took advantage of a lull in winds on Saturday to build containment lines around five percent of the conflagration but warned that gusts were expected to pick up again on Sunday.

The Woolsey Fire broke out on Thursday in Ventura County near Los Angeles and quickly jumped the 101 Freeway, a major north-south artery, in several places.

On Friday, it crossed the Santa Monica Mountains toward Malibu, where flames driven by wind gusts of up to 50 miles per hour (80 kph) raced down hillsides and through canyons toward multi-million dollar homes.

Early on Saturday, flames approached Malibu's Pepperdine University, a private residential college with 7,700 students, where many remained sheltered on the main campus.

School officials told the students that they have been assured by fire officials that the university's buildings were built to withstand fire.

Among those forced to flee the Malibu area were celebrities including Lady Gaga and Kim Kardashian, who said on Twitter that flames had damaged the home she shares in nearby Calabasas with Kanye West.

In Ventura County, most of the town of Thousand Oaks was ordered evacuated, adding to the anguish days after a gunman killed 12 people in a shooting rampage at a bar.

President Donald Trump, weighing in on the emergency during a trip to France, said early on Saturday that "gross mismanagement of forests" was to blame.

"There is no reason for these massive, deadly and costly forest fires in California except that forest management is so poor," he wrote in a Twitter post.

Trump, a Republican, has previously blamed California officials for fires and threatened to withhold funding, saying the state should do more to remove rotten trees and other debris that fuel blazes.

State officials have blamed climate change and say many of the burn areas have been in federally-managed lands.

"Our focus is on the Californians impacted by these fires and the first responders and firefighters working around the clock to save lives and property - not on the President's inane and uninformed tweets," said Evan Westrub, a spokesman for California Governor Jerry Brown.
