Southern Europe is reeling from one of its worst wildfire seasons, with blazes sweeping from Greece to Portugal. At least four people have died—three in Spain and one in Portugal—as thousands are evacuated and nearly 100 injured. Spain faces the heaviest damage, battling more than 14 major wildfires that have destroyed 390,000 acres. Transportation has been disrupted, with highways closed and rail suspended. The EU has deployed firefighting aircraft, while Portugal fights seven large blazes with 4,000 firefighters.
