Ukraine's Nuclear Plant Partly Goes Offline Amid Fighting

The International Atomic Energy Agency (IAEA) reports that Europe's largest nuclear power plant in Ukraine, controlled by Russia, lost connection to its main external power line due to renewed shelling. However, a reserve line is being used for backup power. IAEA experts arrived at the plant amid ongoing conflict, raising fears of a nuclear disaster. The IAEA director general expressed grave concerns but noted the situation is not comparable to Chernobyl. Ukrainian President Zalenski accused Russia of 'radiation blackmail' and called for more sanctions, hoping the IAEA's mission would lead to the plant's demilitarization.
