In France, two major wildfires were spreading in the southern part of the Atlantic coast, despite the efforts of firefighters who have been battling the flames for the past week.
The fires spread to burn a further 300 hectares late on Tuesday, Gironde officials said.
A total of 20,600 hectares of land has burned near Landiras and Teste-de-Buch, south of Bordeaux.
Strong winds and droughts in some areas are fanning other fires in France, including in Brittany, where a wildfire tore through more than 1,700 hectares of forest near Brasparts. Hundreds of people had to be brought to safety.
