 The head of the UN's nuclear power watchdog warned on Saturday that the situation around the Russian-held Zaparizia nuclear station has become potentially dangerous as Moscow installed officials began evacuating people from nearby areas. Rafael Grossi, director general of the International Atomic Energy Agency, called for measures to ensure the safe operation of Europe's largest nuclear plant as evacuations were underway in the nearby town of Enerhodar. The general situation in the area near the Zaparizia nuclear power plant is becoming increasingly unpredictable and potentially dangerous, Grossi said on the agency's website. Grossi said that while the operating staff of the plant remain at the site, the conditions for the personnel and their families are increasingly tense. The Russian-installed governor of the Moscow-controlled part of Ukraine's Zaparizia region said on Friday that he had ordered the evacuation of villages close to the front line as shelling had intensified in the area in recent days. Grossi has repeatedly warned of the dangers of military operations around the plant.
