The International Atomic Energy Agency (IAEA) said electrical substations "vital for nuclear safety" were affected by the massive Russian strike on Ukraine overnight into Tuesday, leading the Chernobyl nuclear power plant to lose all of its off-site power.

At least three people have been reported killed after Russian forces struck the southeastern Ukrainian city of Zaporizhzhia, Governor Ivan Fedorov announced on the Telegram messaging app. Russian strikes also destroyed several private houses and cars, and left nearly 1,500 households without electricity, the governor said.
