President Volodymyr Zelenskiy’s office said the Russians launched an offensive on Sievierodonetsk early on Wednesday and the town was under constant fire from mortars.
Luhansk regional governor Serhiy Gaidai said six civilians were killed and at least eight wounded, most near bomb shelters, in Sievierodonetsk.
“At the moment, with the support of artillery, the Russian occupiers are attacking Sievierodonetsk,” Gaidai said.
Ukraine’s military said it had repelled nine Russian attacks on Tuesday in the Donbas where Moscow’s troops had killed at least 14 civilians, using aircraft, rocket launchers, artillery, tanks, mortars and missiles.
Reuters could not immediately verify information about the fighting.
In the town of Sloviansk west of Donbas, many residents took advantage of what Ukraine said was a break in the Russian assault to leave. “My house was bombed, I have nothing,” said Vera Safronova, seated in a train carriage among the evacuees.
Food blockage
Along with the eastern Donbas region, Moscow is also targeting southern Ukraine and has blockaded ships that would normally export Ukrainian grain and sunflower oil through the Black Sea, pushing up prices globally and threatening lives.
“It cannot be in Russia’s interest that because of Russia, people are dying of hunger abroad,” European Commission President Ursula von der Leyen told Reuters on Tuesday at the World Economic Forum in Davos, calling for a dialogue.
Russia, which has blamed Ukraine and the West for the food crisis, said it was ready to provide a humanitarian corridor for vessels carrying food to leave Ukraine but said Western sanctions would need to be lifted in return.
Russian Deputy Foreign Minister Andrei Rudenko was quoted by Interfax news agency as saying solving the food problem required a “comprehensive approach”. Russia was in touch with the United Nations, and “does not rule out the possibility of global talks to unblock Ukraine’s ports,” he said.
Separately, Russia’s defence ministry said the port of Mariupol, the Ukrainian city taken by Russia last week after devastating bombardment and a three-month siege, was operating normally.
Rudenko said it was premature to establish a Russian military base in Ukraine’s Kherson region, adjacent to Crimea, which Moscow seized from Ukraine in 2014.
