Two crew members were killed and two others survived after two firefighting helicopters collided mid-air while tackling a large wildfire on the Attica-Boeotia border, roughly 65km west of Athens. The dead were a Danish pilot and a Greek fire service liaison officer, while a British pilot and a second Greek coordinator survived the crash, which sent both aircraft into a ravine. The accident occurred amid a week of severe wildfires across Greece that have forced mass evacuations, part of a broader pattern of destructive fires hitting several European countries after prolonged heatwaves.

The Greek Fire Service said the two leased Bell helicopters collided during operations, with one crew rescued alive and the other recovered unconscious before being pronounced dead. Prime Minister Kyriakos Mitsotakis expressed condolences, and all Bell helicopters nationwide have been grounded as a precaution, though other aircraft including Chinooks and Canadair water bombers continue firefighting efforts. More than 500 firefighters have been battling blazes across areas including Porto Germeno, Psatha, Fokida, Megara and Kefalonia over the past 72 hours, while fires in France and Spain earlier in the week, near Bordeaux and Madrid, have now been contained.
