But the crisis worsened in Greece, where gale-force winds drove flames through a seaside resort and triggered fresh evacuations. In southwestern France, firefighters held a vast wildfire within its perimeter, with about 198,000 people now allowed home after what may have been the country’s largest peacetime evacuation. A second French fire that raced across 10 square kilometers (4 square miles) in six hours Friday — “faster than a horse at full gallop,” according to the prefecture — also stopped expanding overnight. Theodore Giannaros, a wildfire meteorologist at the National Observatory of Athens, estimated that 40 to 50 square kilometers (15 to 19 square miles) had been affected, although authorities had not issued an official burned-area figure. “The very strong to gale-force winds continue to create exceptionally difficult conditions,” Climate Crisis and Civil Protection Minister Evangelos Tournas said.
