At least 10 people have been killed as a result of the wildfires, the Los Angeles County Department of Medical Examiner said on Thursday.

The latest fire in Los Angeles is being investigated as a potential arson attack, according to NBC. The blaze, known as the Kenneth Fire, is burning in the city's West Hills area with zero per cent containment as it spreads across nearly 400 hectares.

The Kenneth Fire started around 2 p.m. on Thursday afternoon in an area of dry brush in the Upper Las Virgenes Canyon Open Space just north of the 101 Freeway.

A 960-acre brush fire sparked in the West Hills area near the 101 Freeway Thursday afternoon. The Los Angeles Fire Department said that the fire was quickly burning toward the south, relatively close to homes before they were able to establish perimeter lines.

Forward progress of the Kenneth fire in the West Hills area of Los Angeles and Ventura County was stopped overnight at 1,000 acres as fire crews achieved 35% containment, authorities said Friday morning, Jan. 10. All evacuation orders and warnings within Los Angeles were lifted by Thursday evening, officials said.

A fire has broken out at the border of Los Angeles and Ventura counties and is spreading rapidly, threatening numerous hillside homes in the Calabasas and Hidden Hills areas.
