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

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.

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.
