Wildfires in the south of France have revealed a cache of 400 historic shells and munitions in the village of Le Porge, according to local authorities. Blasts during the fires, initially thought to be exploding gas cylinders, may have been World War Two explosives detonated by the heat, the local fire commander told local media. More than 100 explosions were heard on the second night of the fire, Mayor Martial Zaninetti told French news outlet France Info, likening it to "the sound of war". "There were ammunition depots buried in land within our municipality, but we didn't know it, and they exploded", Zaninetti told France Info. He described them going "to the right, to the left" and that there was "even one that went through a house".
