French authorities have ordered the evacuation of almost 60,000 people near Bordeaux, bringing the total number of people told to flee wildfires in France and Spain to more than 220,000.
About 200,000 people have been evacuated in southwestern France in the Gironde and Landes regions. French President Emmanuel Macron has mobilized the army to help in the response.
Meanwhile, a fire near Madrid is "beyond the capacity" of firefighters to bring it under control, Spanish officials have warned, after three fires west of the capital merged into a single blaze.
Spain's government has declared a national state of emergency, with 25,000 people instructed to evacuate and almost 40,000 others to stay indoors.
Madrid's regional president, Isabel Díaz Ayuso, described it as "the worst fire in the history of the region", with the area facing a "perfect storm" of high temperatures, relentless winds and merging fire fronts.
In Spain, local emergency services said the fires were moving towards the municipalities of Robledo de Chavela and Fresnedillas de la Olivia, about 50 km from the capital.
"The wildfire is at its peak and is currently beyond the capacity of firefighters to control it," Carlos Novillo, the Madrid regional government's head of emergency management, told reporters.
"It is not possible to attack the fire in that area, so protective measures are being taken," he added.
