There's a fire at Ukraine's largest nuclear plant. The facility, also Europe's largest plant, caught fire early Friday after enduring heavy shelling from Russian forces in the southern Ukrainian city of Enerhodar, raising concerns about a nuclear accident. Plant spokesman Andriy Tuz told Ukrainian television that shells were falling directly on the Zaporizhzhia plant and had set fire to one of the facility’s six reactors. That reactor is under renovation and not operating, but there is nuclear fuel inside, he said. Tuz said it's urgent to stop the fighting so the flames can be extinguished. “We demand that they stop the heavy weapons fire,” Tuz said in a video posted on Telegram. “There is a real threat of nuclear danger in the biggest atomic energy station in Europe.” 📸 Zaporizhzhia Nuclear Authority
