Temperatures are expected to soar past 40C in some regions as a heatwave builds, further hampering firefighting efforts.

Firefighters in France's Gironde region face an "unprecedented" situation as they battle a blaze that "has a life of its own", the interior minister warns Spain and France are bracing for new heatwaves with temperatures expected to soar past 40C in some regions. Spain's national weather service says the severe weather is forecast to last until "at least" Sunday, and warns of "extreme" fire risks as firefighters continue to battle the some of the worst blazes in the country's history. France's south-west regions Gironde and Landes are under "yellow alert" for a heatwave expected to peak on Wednesday, further hampering efforts to contain "very unpredictable" blazes in Gironde. The mayor of Bordeaux has said he is preparing for "all eventualities", as one of the wildfires burning in France is 15km (nine miles) from the south-western city. "We are preparing to accommodate a large number of people should further evacuations be ordered," said Thomas Cazenave. Some 220,000 people have been evacuated in France and more than 100,000 in Spain, where fires are burning "uncontrolled" west of Madrid. President Emmanuel Macron, visiting the fire-ravaged area in the Gironde region, said the country was facing a "completely unprecedented wildfire" - the "toughest since World War Two".
