A Greek and a Danish national died and two others were hospitalized following the collision on Sunday. Areas surrounding the Greek capital remain at high risk through the week with temperatures set to rise further. 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.
