LOS ANGELES (Reuters) - Four people, including a homeless person and two hikers, have died from the record-breaking heat in the U.S. Southwest, media reports said, where triple-digit temperatures have driven residents indoors and cancelled airline flights.

The first two fatalities recorded in the three-day heatwave took place on Monday in Santa Clara County, California, south of San Francisco, and included a homeless person found in a car, the San Jose Mercury News reported.
