The reports of nearby shelling, which could not be independently verified, have caused international alarm. The head of the International Atomic Energy Agency, Rafael Grossi, warned the UN Security Council on Tuesday that “something very, very catastrophic could take place” at Zaporizhzhia.
“There are fires, blackouts and other things at the (plant) that force us to prepare the local population for the consequences of the nuclear danger,” Reznichenko said.
The potential peril led the UN atomic watchdog agency to urge Russia and Ukraine to establish a “nuclear safety and security protection zone” around the plant.
There are fears the fighting could trigger a catastrophe on the scale of the Chernobyl disaster in 1986. The plant was built during the Soviet era and is one of the 10 biggest in the world.
Neither Moscow nor Kiev officials would immediately commit to the idea of a safety zone, saying more details of the proposal were needed.
The plant is currently generating electricity only to power its safety systems, a senior Ukrainian official said.
Any further disruption could force the plant to use a back-up diesel generator, but that would entail bringing four diesel transport trucks a day through the fighting, said Oleh Korikov, acting Chief State Inspector for the Nuclear and Radiation Safety of Ukraine.
“We could potentially be in a situation where we run out of diesel,” he said. “And this can lead to an accident with damage to the active zone of the reactors, and, accordingly, the release of radioactive products into the environment.”
Authorities could consider shutting down the plant, he said, without offering details about how that would work.
Russian President Vladimir Putin defied pressure to halt the war, saying Wednesday that Moscow will forge ahead with its military offensive in Ukraine until it achieves its goals. He also mocked Western attempts to stop Russia with sanctions.
The eastern city of Sloviansk came under Russian fire on Wednesday morning, damaging a school and another building, according to the head of the city administration Vadym Lyakh.
Firefighters in the city dug deep into the still-smoldering rubble of an apartment building and removed at least one body bag.
Chunks of bricks, masonry and concrete lay among the torn branches of nearby trees, mixed with broken glass and roof tiles. Metal doors, buckled by the force of the blast, hung off their hinges.
The strike came at around 4 am, said local resident Raisa Smelkova, 75, who lives in another part of the building. She and her husband were unhurt.
Smelkova and her husband lived through the previous war in Ukraine in 2014, when Russia annexed the Crimea region. But this time, she said, things are much worse.
“What is happening now is not just scary, it’s gruesome,” she said. “There is more destruction. Everything is worse. Just everything.”
Three civilians were killed in Russian shelling in the Donetsk region, the Ukrainian presidential office said. Kharkiv city was hit by rockets twice during the night.
But Ukrainian forces have taken control of an unspecified number of towns in the Kherson region, according to Nataliya Humenyuk, a spokesperson for the southern military command. She said details would come later from the military leadership.
The UK defense ministry said there had been heavy fighting on three fronts: in the north, near Kharkiv; in the east in the Donbas; and in the south in Kherson Oblast.
Amid a Ukrainian counterattack in the east, “multiple concurrent threats spread across 500 kilometers (310 miles) will test Russia’s ability to coordinate operational design and reallocate resources across multiple groupings of forces,” the ministry said Wednesday.
The Russian military held large-scale military drills that began last week and ended Wednesday in the country’s east that involved forces from China. It was seen as another show of increasingly close ties between Moscow and Beijing amid tensions with the West over the military action in Ukraine.
