The UN's nuclear watchdog said on January 3 that its experts had recently been blocked for the first time from inspecting the reactor halls of three units of Ukraine's Zaporizhzhya power plant. International Atomic Energy Agency (IAEA) experts "for the past two weeks...have not been allowed to access the reactor halls of units 1, 2 and 6," IAEA Director-General Rafael Grossi said in a statement. The nuclear plant was captured by Russian forces in 2022, and both sides have accused each other of compromising its safety.
