What's the latest on the LA fires, and what caused them?
Out-of-control wildfires are ripping across parts of Los Angeles, leading to at least five deaths, burning down hundreds of buildings, and prompting more than 130,000 people to flee their homes in America's second-largest city.
Despite the efforts of firefighters, the biggest blazes remain totally uncontained - with weather conditions and the underlying impact of climate change expected to continue fanning the flames for days to come.
What's the latest?
More than 137,000 people have been forced to leave their homes - many of them simply carrying whatever belongings they can.
Police say at least five people have died, and their bodies found near the Eaton Fire - but their cause of death is not yet known.
Like the even larger Palisades Fire, the Eaton Fire remains totally uncontained. Meanwhile, the new Sunset Fire is menacing the well-known Hollywood Hills area.
More than 1,000 structures are known to have been destroyed - including houses, schools and businesses on the iconic Sunset Boulevard. A fire ecologist has told the BBC that "entire neighbourhoods... have been wiped out".
Among the celebrities who have lost their homes are Leighton Meester and Adam Brody, who attended the Golden Globes just days ago, and Paris Hilton.
There is a glimmer of hope for firefighters, as the fire weather outlook for southern California has been downgraded from "extremely critical" to "critical".
But BBC weather forecaster Sarah Keith-Lucas says there is no rain forecast in the area for at least the next week, meaning conditions remain ripe for fire.
Mass disruption has been reported due to traffic buildup. A number of schools and the the University of California, Los Angeles (UCLA) have been forced to close.
A political row about the city's preparedness has erupted after it emerged that some firefighters' hoses have run dry - an issue seized upon by US President-elect Donald Trump.
Where are the fires?
There are at least five fires raging in the wider area, according to California fire officials early on Thursday:
- Palisades: The first fire to erupt on Tuesday and the biggest fire in the region, which could become the most destructive fire in state history. It has scorched a sizable part of land, covering more than 17,200 acres, including the upscale Pacific Palisades neighbourhood
- Eaton: It has struck the northern part of Los Angeles, blazing through cities such as Altadena. It's the second biggest fire in the area, burning around 10,600 acres
- Hurst: Located just north of San Fernando, it began burning on Tuesday night and has grown to 855 acres, though firefighters have had some successlimited in containing it
- Lidia: It broke out on Wednesday afternoon in the mountainous Acton area north of Los Angeles and grew to cover almost 350 acres. Authorities say it has been 40% contained
- Sunset: It broke out Wednesday evening in Hollywood Hills, growing to about 20 acres in less than an hour. It now covers around 43 acres
The earlier Woodley and Olivas fires have now been contained, according to local fire authorities.
How did the LA fires start?
Officials have pointed to high winds and drought in the area, which has made vegetation very dry and easy to burn.
The likely impact of climate change has also been cited been blamed - although the exact circumstances remain unclear.
Some 95% of wildfires in the area are started by humans, according to David Acuna, a battalion chief at the Californian Fire Service, although officials are yet to state how they think the current fires started.
An important factor that has been cited in the spread of the blazes is the Santa Ana winds, which blow from inland towards the coast. With speeds of more than 60mph (97 km/h), these are believed to have fanned the flames.
What role has climate change played?
Although strong winds and lack of rain are driving the blazes, experts say climate change is altering the background conditions and increasing the likelihood of such fires.
US government research is unequivocal in linking climate change to larger and more severe wildfires in the western United States.
"Climate change, including increased heat, extended drought, and a thirsty atmosphere, has been a key driver in increasing the risk and extent of wildfires in the western United States," the National Oceanic and Atmospheric Administration says.
And following a very warm summer and lack of rain in recent months, California is particularly vulnerable.
Fire season in southern California is generally thought to stretch from May to October - but the state's governor, Gavin Newsom, has pointed out earlier that blazes had become a perennial issue. "There's no fire season," he said. "It's fire year."
Speaking to the BBC, Mr Acuna said the Palisades Fire represented only the third occasion in the past 30 years that a major fire had broken out in January.
