A potentially deadly heatwave has hit Western USA with temperatures threatening to break the all-time high recorded on earth.

That temperature, 56.7C (134F), was recorded a century ago in California.

In Phoenix, Arizona, the mercury hit 47C (116F) on Friday, and in the desert of Death Valley, California, the thermometer approached 51C.
