A historic wildfire crisis in southwestern France and nearby Spain has forced about 260,000 people to evacuate, with Bordeaux and Cap Ferret among hardest hit as fires threaten major population centers. France has mobilized the military and intensified firefighting, deploying hundreds of personnel and conducting large-scale evacuations in the Gironde and Landes regions, while Spain has evacuated tens of thousands near Madrid and other communities. Fire conditions are highly volatile, with pyrocumulonimbus clouds and shifting winds complicating containment and prompting temporary closures of airports, rail, and roads, along with retardant aircraft. The scale of the response has affected national events, with the Tour de France shortened and security reinforcements redirected to the fires. International aid and widespread shelters are being organized as authorities warn the fires may remain dangerous for an extended period, with some casualties reported in Spain and ongoing threats to residents and tourists. Officials say the situation is unprecedented in recent memory, testing emergency services across both countries.
