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.

Two massive wildfires menacing Los Angeles from the east and west devoured nearly 10,000 homes and other structures, burning into a third night even as the fierce winds eased and gave firefighters a welcome but temporary respite.

Water experts dismissed Trump’s claims that California water policy is to blame for dry hydrants. But Los Angeles is also unprepared for the age of urban wildfires.
