KYIV—Ukraine said on Thursday it had been forced to cede some territory in the east of the country in the face of a Russian offensive, and the head of the NATO military alliance said Moscow must not be allowed to win the war.
Ukrainian President Volodymyr Zelenskyy this week described the pressure his armed forces were under in the Donbass region in eastern Ukraine as "Hell." He spoke of fierce fighting around the town of Avdiivka and the fortified village of Pisky, where Kyiv has acknowledged its Russian foe's "partial success" in recent days.
The Ukrainian military said on Thursday Russian forces had mounted at least two assaults on Pisky but that its troops had managed to repel them.
Ukraine has spent the last eight years fortifying defensive positions in Pisky, viewing it as a buffer zone against Russian-backed forces who control the city of Donetsk about 10 km (6 miles) to the southeast.
General Oleksiy Gromov told a news conference that Ukrainian forces had recaptured two villages around the eastern city of Sloviansk, but had been pushed back to the town of Avdiivka's outskirts after being forced to abandon a coal mine regarded as a key defensive position.
The Russian defense ministry confirmed its offensive.
It said its forces had inflicted heavy losses on Ukrainian forces around Avdiivka and two other locations in Donetsk Province, forcing Kyiv's mechanized and mechanized infantry units to withdraw.
Reuters could not immediately verify either side's assertions.
Video footage released by the Russian defense ministry showed Russian rocket launchers in action and tanks advancing and firing at speed across open terrain. It was not clear where they were filmed.
Some unverified reports suggest that Russian-backed forces have reached Pisky's outskirts.
Supplied with arms by the West, Ukraine has been attacking Russian-backed forces in the area too.
Officials in the Russian-backed self-proclaimed Donetsk People's Republic (DPR) said on Thursday that Ukrainian shelling had killed at least five people and wounded six in Donetsk city.
Pavlo Kyrylenko, the Ukrainian governor of Donetsk, said on Telegram that three civilians had been killed by Russian shelling in Bakhmut, Maryinka, and Shevchenko and five wounded in the past 24 hours.
Eight people had been killed and four wounded by Russian artillery shelling in the town of Toretsk in Donetsk, he said.
Russia has said it plans to take full control of the wider Donetsk Province, one of two that make up the industrialized Donbass region, as part of what it calls a "special military operation" to safeguard its security from what it calls unjustified NATO enlargement.
NATO Warning
Ukraine said the Russian offensive in the east looked like an attempt to force it to divert troops from the south where Kyiv's forces are trying to retake territory and destroy Russian supply lines as a prelude to a wider counter-offensive."The idea is to put military pressure on us in Kharkiv, Donetsk and Luhansk over the next few weeks ... What is happening in the east is not what will determine the outcome of the war," Ukrainian Presidential Adviser Oleksiy Arestovych said in an interview on YouTube.
General Oleksiy Gromov said Russia might launch its own offensive in the southern Ukrainian region of Kherson to try to win back momentum in the war after building up its forces there.
NATO Secretary-General Jens Stoltenberg said on Thursday the war was the most dangerous moment for Europe since World War Two and that Russia must not be allowed to win it.
To prevent Moscow from succeeding, NATO and its member countries may have to support Ukraine with arms and other assistance for a long time to come, he said.
"It's in our interest that this type of aggressive policy does not succeed," Stoltenberg said in a speech in his native Norway.
Amid fears among some politicians in the West that Russia's ambitions may extend beyond Ukraine, Stoltenberg warned Putin that the response to such a move from the Western military alliance would be overwhelming.
The war has led previously non-aligned Finland and Sweden to seek NATO membership, with the request so far ratified by 23 of the 30 member states, including the United States.
