U.N. nuclear chief urges Russia and Ukraine to ban attacks at Zaporizhzhia nuclear power plant

The U.N. nuclear chief stressed Tuesday that the world is fortunate a nuclear accident hasn't happened in Ukraine and asked Moscow and Kyiv to commit to preventing any attack on Europe's largest nuclear power plant and make other pledges "to avoid the danger of a catastrophic incident."

Rafael Mariano Grossi reiterated to the U.N. Security Council what he told the International Atomic Energy Agency's board of governors in March: "We are rolling a dice and if this continues then one day our luck will run out."

The IAEA director-general said avoiding a nuclear accident is possible if five principles are observed at the Zaporizhzhia nuclear power plant, where fighting on seven occasions, most recently last week, disrupted critical power supplies, "the last line of defense against a nuclear accident."
