US heatwave: Wildfires rage in western states as temperatures soar

Wildfires are raging in the west of the United States as the region is hit by a heatwave that has brought record temperatures to several areas.

Communities have been told to evacuate as firefighters struggle to battle the blazes in the extreme conditions. In California, residents were urged to cut power consumption after interstate power lines were knocked out.

On Saturday, two firefighters in Arizona died when their aircraft crashed while responding to a blaze. Meanwhile, Las Vegas, Nevada, matched its all-time temperature high of 47.2C (117F) on Saturday.
