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.

Firefighters battled Thursday to control a series of major fires in the Los Angeles area that have killed seven people, burned at least 10,000 structures from the Pacific Coast to Pasadena and sent thousands of people frantically fleeing their homes.
