The head of the UN nuclear watchdog issued an urgent warning after Vladimir Putin launched a huge wave of missile and drone strikes on Ukraine knocking the Zaporizhzhia nuclear power plant off the electricity grid.
The capital Kyiv, the second largest city of Kharkiv in the east, and the Black Sea port of Odesa were all hit in the attacks on a wide arc of targets, from Zhytomyr, Vynnytsia and Rivne in the west to Dnipro and Poltava in central Ukraine, officials said.
