Wildfires west of Athens jumped containment lines a day after a midair collision between two helicopters killed two crew members. The wildfire burned about 420 square kilometers (162 square miles), making it France’s largest wildfire on record. About 1,500 firefighters, supported by water-dropping helicopters, continued reinforcing fire lines along the blaze that tore through about 18 square kilometers (7 square miles). The Dutch air force sent two Chinook helicopters equipped with large water containers to help firefighters tackle the blaze. Media reported that a campsite in the area was evacuated due to poor air quality caused by a large plume of smoke.
