A firefighting plane battling a forest fire near the southern French commune of Générac crashed on Friday, killing its pilot, local authorities said, reports Deutsche Welle.
The accident occurred at 5:.20 p.m. local time as more than 500 firefighters and police officers were fighting three separate fires in the Gard département [county] of France.
"A Civil Security Tracker pilot tragically lost his life while bravely fighting an ongoing fire," the Gard's police department said in a statement. "A judicial inquiry is underway under the authority of the public prosecutor who has visited the site."
The blaze has destroyed nearly 800 hectares (1,980 acres) of forest, heathland and vineyards in the area around Generac since Tuesday. Authorities were battling three separate fires on Friday near the small communes of Vauvert, Générac and Montignargues.
Regional prosecutor Eric Maurel said the fire may have been started deliberately.
The Tracker plane is the smallest aircraft to fight forest fires, with the ability to carry up to 3,600 litres of water.
French Prime Minister Edouard Philippe and interior minister Christophe Castaner both took to Twitter to offer their condolences.
