The Hollywood Hills blazed uncontrollably on Thursday morning as the worst wildfires in the history of Los Angeles raged across the city and deep into the storied heartland of the American film industry.

Combined, the fires have consumed about 22 square miles — about half the size of the entire city of San Francisco.

Raging wildfires surrounding Los Angeles spread to the Hollywood Hills on Wednesday, after five other fires in the area killed at least five people, destroyed hundreds of homes and stretched firefighting resources and water supplies to the limit.
