The UN atomic watchdog chief is expected on Wednesday to visit Ukraine's Zaporizhzhia nuclear power plant, which is currently held by Russian forces.
There are persistent fears about the safety of the nuclear plant -- Europe's largest -- which is located in the southern Zaporizhzhia region where there has been frequent shelling since Russian troops invaded.
This will be Grossi's second visit to Zaporizhzhia since Russia invaded Ukraine in February last year, and he plans to "assess first-hand the serious nuclear safety and security situation at the facility", according to the IAEA.
