Ukraine says a renewed Russian shelling has damaged three radiation sensors and injured a worker at the Zaporizhzhia power plant, the second hit on Europe's largest nuclear facility in a row in a row.
Ukrainian President Volodymyr Zelenskyy called the shelling Russian nuclear terror that warranted more international sanctions, this time on Moscow's nuclear sector.
There is no such nation as the world that could feel safe when a terrorist state attacks a nuclear plant, Mr Zelenskyy said in a televised address.
The Russian-installed authority of the area said it was Ukraine that hit the site, damaging administrative buildings and an area near a storage facility.
There was no way that neither account could be independently verified.
The events at the Zaporizhzhia site - where Kyiv had previously alleged Russia had hit a power line on Friday - have alarmed the world.
A deal to unblock Ukraine's food exports and relax global shortages saw another four ships sail out of Ukrainian Black Sea ports, according to the International Atomic Energy Agency.
The four outgoing ships are carrying more than 170,000 tons of corn and other food and are sailing under a deal that was brokered by the United Nations and Turkey to help with the rising global food prices resulting from the war.
Russian President Vladimir Putin called Russia and Ukraine a special military operation, which together accounted for almost one-third of global wheat exports.
Since then, the disruption has threatened famine in some parts of the world.
Russian troops are trying to gain full control of the Donbas region in eastern Ukraine, where pro-Moscow separatists seized territory after the Kremlin annexed Crimea to the south in 2014.
Russian forces stepped up their attacks north and northwest of the city of Donetsk in the region, according to Ukraine's military, reporting Russians attacked Ukrainian positions near the heavily fortified settlements of Piski and Avdiivka, as well as shelling other locations in the Donetsk region.
Russia is armed in southern Ukraine in a bid to prevent a possible counter-offensive near Kherson, in addition to tightening its grip on the Donbas region.
Russians have started to play along with the idea of joining Ukraine's occupied territory in the wake of Moscow's invasion. In his video address, a senior pro-Russian official said a referendum on such a move would be held next year. In his video address, Mr Zelenskyy said that any pseudo-referendums on occupied areas of his country joining Russia would eliminate the possibility of talks between Moscow and Kyiv or its allies.
The Russian side will need a change in the talks with Ukraine and the free world at some point, according to Zelenskyy.
Ukraine's chief war-crimes prosecutor said more than 26,000 suspected war crimes committed since the invasion were being investigated, with 135 people being charged, of which 15 were in custody. Russia denies targeting civilians.
There were overnight reports of shelling and missile strikes in the Ukrainian city of Kharkiv and around military sites in the western Vinnytsia, among other places, Ukrainian authorities said. There was no immediate word on the casualties.
