California fires live updates: At least 10 fire-related deaths, medical examiner says

Los Angeles County Fire Chief Anthony Marrone appeared at a press conference alongside Mayor Karen Bass and described the origins of the Eaton Fire as "unknown."

He said that it remained under investigation, expressing confidence that those responsible would be caught in the event that foul play was involved.

Over 750 personnel were fighting on the front lines of the Eaton Fire, he said, citing the five deaths, many injuries and over 1,000 structures damaged or destroyed.

As the fires raged on, he said that LA was requesting additional support from both Northern California and the surrounding states, with over 100 units on their way to assist.

Sheriff Robert Luna also spoke at the briefing and emphasized the cooperation taking place throughout and beyond the state to ensure the public's safety. Naming Pasadena and Santa Monica in particular, he said that law enforcement throughout the region was working together and supporting each other's work.

Woodley Fire, one of five that had been active throughout the afternoon and spread to over 30 acres, was under control, LA Mayor Karen Bass said at an early evening update on the multiple fires raging throughout the County of Los Angeles.

However, she cautioned, "We are very much still in an active firefight."

The announcement came minutes ahead of a new fire's eruption in the Hollywood Hills: the Sunset Fire.

Fortunately, winds had subsided enough that air support was able to resume, the mayor said, explaining that this effort would make a significant difference in the ongoing fight.

"We are fighting for you," Bass said. She thanked everyone who heeded the call to evacuate and suggested that further orders were likely to come throughout the evening.

Regardless of the hardships and unknowns, she assured the public that she had been in touch with both President Joe Biden and California Gov. Gavin Newsom and said, "They assured me of full federal and state support."

"Make no mistake," she said, "Los Angeles will rebuild."

The rapidly spreading Sunset Fire in the Hollywood Hills has sparked an evacuation for a heavily populated area of the city.

The immediate evacuation order includes an area bounded by Laurel Canyon Boulevard to the west, Mulholland Drive to the north, the 101 Freeway to the east and down to Hollywood Boulevard to the south, according to the LA Fire Department.

A map of the mandatory evacuation zone is posted on the LAFD website.

Margaret Stewart, LAFD public information officer, told KABC some 20 additional fire engines were en route, calling it a "very dynamic situation" and an "explosive fire" that has "blown up in Runyon Canyon."

A new fire has broken out in the famed Runyon Canyon of Hollywood Hills. It is being referred to as the Sunset Fire.

The Los Angeles Fire Department was surveying the scene for the first time at approximately 5:45 p.m. local time. It then characterized the breakout as approximately 10 acres in size.

Observing the fire in real time, KABC’s Chris Cristi said, "This is the most ominous situation."
