Multiple wildfires, including the Palisades Fire and Eaton Fire, are raging across southern California Thursday, leaving at least 5 dead and burning more than 27,000 acres, officials say. Police have arrested 20 suspected looters.

Firefighters are battling to control a series of major fires in the Los Angeles area that have killed five people, ravaged communities from the Pacific Coast to Pasadena and sent thousands of people frantically fleeing their homes.

The wildfires that destroyed homes in multiple sections of the Los Angeles area will test California’s efforts to stabilize the state’s insurance marketplace after many insurers stopped issuing residential policies due to the high fire risk.
