KYIV—Ukraine narrowly escaped disaster during fighting at the weekend that rocked Europe’s largest atomic power plant with a barrage of shells, some falling near reactors and damaging a radioactive waste storage building, the U.N. nuclear watchdog said.
Russia and Ukraine on Monday traded blame for at least a dozen explosions at Ukraine’s Zaporizhzhia nuclear power station, which has been under Russian control since soon after it invaded the country on Feb. 24 but is across the Dnipro river from areas controlled by Kyiv.
