A wildfire burning out of control in southwestern France has forced the evacuation of 10,000 people from ​two dozen small towns and villages near the Spanish border, and officials said strong winds on Monday would further fan the blaze.

The fire has scorched some 4,600 hectares in the foothills of the French Pyrenees, local ​prefect Pierre Regnault de la Mothe said in a post on ​X.

“This morning conditions are deteriorating again,” Interior Minister Laurent ⁠Nunez warned on French TV station TF1. “Today the battle resumes.”

Early summer ​heatwaves in France and across western Europe in May and June have ​scorched vast areas of land, making them particularly vulnerable to wildfires this year.

The Trevillach blaze is burning in the vicinity of the third stage of the Tour ​de France. Local authorities have closed the leg to the public ​to allow emergency services easy access to the area. Although the race will proceed, ‌the ⁠motorcade of team vehicles that follows will now be kept to a minimum.

On the Spanish side of the border, the fire ravaged 2,200 hectares — 97% of them in the protected natural area of Les Gavarres — ​but Catalan authorities ​said late on ⁠Saturday that it was stable and would be completely extinguished during the week.

Police have arrested an employee ​of a company contracted by Catalonia’s regional government who ​is suspected ⁠of having sparked the wildfire by using an angle grinder at the side of a road.

South of Catalonia, in the eastern Castellon province, 500 ⁠people ​were evacuated after a wildfire entered the ​Sierra de Espadan national park, home to a significant cork oak forest.
