The European Union has asked the U.N. nuclear watchdog to safeguard Ukraine's nuclear plants, two of which are now under Russian control, and mobilise international help in case of an emergency, according to a letter seen by Reuters.
Russian forces have seized Ukraine's Zaporizhzhia nuclear power plant, Europe' biggest, and the spent-fuel and radioactive waste facilities at Chernobyl, next to the now defunct power plant where the world's worst nuclear accident happened in 1986.
