UN chief Antonio Guterres will meet the leaders of Ukraine and Turkey in Lviv on Thursday, following a deal reached last month that allowed the resumption of grain exports after Russia's invasion blocked essential global supplies.
The meeting also comes a day after the head of NATO said it was "urgent" that the UN's atomic watchdog be allowed to inspect Ukraine's Zaporizhzhia nuclear power plant, where a Russian occupation has sparked concerns of a nuclear accident.
