Multiple wildfires, including the Palisades Fire and Eaton Fire, are raging across Southern California Friday, leaving at least 10 dead and burning more than 10,000 homes across 27,000 acres, officials say.

Three hundred Oregon firefighters have arrived in Southern California, and many of them have started fighting the fires that have devastated Los Angeles and killed at least 10 people.

The fires’ proximity to densely populated areas means they are burning through more structures than past fires that covered more territory, preliminary figures show.
