Massive blazes that have spread across California have so far led to 7 deaths and the evacuation of thousands of people across the state, with tens of thousands of homes in danger.
The authorities say that lightning is responsible for the fires, over 650 of which have broken out amid a blistering heatwave.
At least 700 buildings have been destroyed and others damaged by the fires, which are being fought by 14,0000 firefighters, 2,400 engines and 95 aircraft.
