KYIV, Ukraine—The U.N. atomic watchdog agency urged Russia and Ukraine on Tuesday to establish a “nuclear safety and security protection zone” around the Zaporizhzhia power plant amid mounting fears the fighting could trigger a catastrophe in a country still scarred by the Chernobyl disaster.
“We are playing with fire, and something very, very catastrophic could take place,” Rafael Grossi, head of the International Atomic Energy Agency (IAEA), warned the U.N. Security Council, days after leading an inspection visit to the plant.
