Russian and Ukrainian troops engaged in close-quarter combat in an eastern Ukraine city on Sunday as Moscow’s soldiers, supported by intense shelling, attempted to gain strategic footholds in the region while facing fierce Ukrainian resistance.
Ukrainian regional officials reported that Russian forces were “storming” the eastern city of Sievierodonetsk, where the fighting has knocked out power and mobile phone services and terrorised civilians who have not fled.
Sievierodonetsk, a manufacturing centre, has emerged as an epicentre of Russia’s quest to conquer Ukraine’s industrial Donbas region. Russia also stepped up its efforts to take nearby Lysychansk, where Ukrainian officials reported constant shelling.
The two cities, with a combined pre-war population of around 200,000, are the last major areas under Ukrainian control in Luhansk province, which makes up the Donbas together with neighbouring Donetsk. Russia is focused on capturing parts of both not already controlled by pro-Moscow separatists.
Russian forces have made small advances in recent days as bombardments ate away at Ukrainian positions and kept civilians trapped in basements or desperately trying to get out safely.
Attacks on military targets throughout the country also caused casualties in civilian areas.
In his Saturday night video address, Ukrainian President Volodymyr Zelensky described the situation in the east as “very complicated” and “indescribably difficult”.
The “Russian army is trying to squeeze at least some result” by concentrating its attacks there, he said.
Sievierodonetsk Mayor Oleksandr Striuk said there was fighting at the city’s bus station on Saturday. A humanitarian centre was unable to operate due to the danger, he said, and mobile phone services and electricity were knocked out. Residents risked exposure to shelling to get water from a half-dozen wells, he added.
However, some supply routes were functioning, and evacuations of the wounded were still possible, Mr Striuk said. He estimated that 1,500 civilians in the city, which had a pre-war population of around 100,000, have died from the fighting as well as from a lack of medicine and diseases that could not be treated.
Regional governor Serhiy Haidai claimed the Russians had retreated “with losses” around the village of Bobrove, around 12 mile (20km) south-east of Sievierodonetsk, but were carrying out air strikes on a nearby village on the strategic Siverskiy Donetsk river.
“The situation in Lysychansk is severe due to constant shelling by the occupiers; there are fatalities and wounded people,” he wrote on Telegram, without elaborating.
On Saturday, he said, one civilian died and four were injured when a Russian shell hit a high-rise apartment building. A local cinema and 22 other residential buildings were also damaged, he said.
The Ukrainian military said on Sunday morning that Russian forces were trying to strengthen their positions around Lyman, a small city that serves as a key rail hub in the Donetsk region.
“The enemy is reinforcing its units,” the Ukrainian armed forces’ General Staff said in an operational update. “It is trying to gain a foothold in the area.”
Moscow claimed on Saturday to have taken Lyman, but there was no acknowledgement of that from Kyiv authorities.
The Ukrainian army said heavy fighting was continuing around Donetsk, the provincial capital.
It also said Russia had launched an offensive on Saturday night around the city of Bakhmut, in the neighbouring Luhansk region, but had been pushed back.
In the same operational update, the military hinted at high levels of casualties sustained by Moscow, claiming that civilians were no longer being admitted to hospitals in Russia-annexed Crimea as beds were needed by injured troops.
It was not immediately possible to verify the accuracy of these claims.
More widely, Russia launched renewed air strikes overnight on Ukraine’s northern Kharkiv and Sumy regions, Ukrainian state agencies said.
The State Emergency Service of Ukraine said on Sunday morning that Russian shelling had caused fires around Kharkiv, the country’s second-largest city.
Russia has kept up a bombardment of Kharkiv, located in north-eastern Ukraine, after Ukrainian fighters pushed its forces back from positions near the city several weeks ago.
Mr Zelensky visited Kharkiv on Sunday.
The regional governor, Oleh Syniehubov, told the president that Russian troops remained in possession of around 30% of the Kharkiv region, while Kyiv’s troops had recaptured another 5%.
Mr Syniehubov reported that Russian attacks had destroyed more than 2,000 apartment buildings, with the northern and eastern parts of Kharkiv city particularly affected.
Mr Zelensky also met with Ukrainian soldiers stationed in Kharkiv.
“I feel boundless pride in our defenders. Every day, risking their lives, they fight for Ukraine’s freedom,” he wrote in a Telegram post.
The Ukrainian Border Guard Service said border areas in the Sumy region, east of Kharkiv, were hit with six unguided missiles.
The agency did not mention reports of any casualties.
Russia claimed its forces destroyed an important Ukrainian ammunition depot in Kryvyi Rih, a city in central Ukraine that is Mr Zelensky’s home town.
High-precision missiles struck a depot located “within one of the industrial enterprises”, Russian Defence Ministry spokesman Igor Konashenkov said.
Ukrainian emergency services confirmed an industrial plant in Kryvyi Rih caught fire after a strike by two Russian rockets and sustained “significant damage”.
Officials did not say whether it was being used as a military depot.
