Wildfires raged for the third straight day, destroying swaths of America’s most populated county and displacing tens of thousands of residents, with firefighters struggling to contain the biggest blazes.

Out-of-control wildfires are ripping across parts of Los Angeles, leading to at least five deaths, burning down hundreds of buildings, and prompting more than 130,000 people to flee their homes in America's second-largest city.

As wildfires roar into residential neighborhoods, firefighters in California and elsewhere are finding that water systems can’t keep up with the demand.
