STORY: Ukraine's nuclear power plant, the largest in Europe, has once again come under attack, prompting the UN to warn of a potential nuclear disaster.
The Zaporizhzhia plant in southern Ukraine is under Russian control.
It was rocked by more than a dozen blasts on Saturday evening and Sunday, according to the International Atomic Energy Agency (IAEA).
The head of the UN watchdog, Rafael Grossi, said the explosions were extremely disturbing, and whoever was doing it was: "playing with fire".
Both Russia and Ukraine have blamed each other for the attacks.
This is Russia's defense ministry spokesman...who accuses Kiev of firing shells at power lines supplying the plant.
The Ukrainian nuclear energy firm, Energoatom, accused Russia of targeting infrastructure, in an attempt to further limit Ukraine's power supply.
The IAEA team on the ground said there had been damage to some buildings, systems and equipment, but none of them critical for nuclear safety and security -- so far.
Repeated shelling of the plant has raised concern about the potential for a grave accident, just 300 miles from the site of the 1986 Chornobyl disaster.
Elsewhere in southern Ukraine, hundreds of people in the city of Kherson flocked to buy groceries on Sunday...
at the first Ukrainian supermarket to open since the city was retaken by Ukrainian forces over a week ago.
During the near-nine months of occupation, the Russian-installed government had brought in Russian-sourced goods and even introduced the ruble as currency.
As the Russian forces retreat, they are moving to reinforce positions in the eastern Donetsk and Luhansk,
where Ukraine's President said on Sunday there had been fierce fighting and artillery fire.
