Russia-Ukraine war: fighting in Donbas ‘difficult and painful’, Zelenskiy says; 9 million Ukrainians without power – live

Ukraine’s President Volodymyr Zelenskiy has said fighting in the eastern regions of Bakhmut, Kreminna and other areas in Donbas are “difficult and painful” for Ukrainian troops.

Addressing the situation on the frontline in his Monday night address, he said:

The frontline. Bakhmut, Kreminna and other areas in Donbas, which now require maximum strength and concentration.

The situation there is difficult, acute. The occupiers are using all the resources available to them – and these are significant resources – to squeeze out at least some advance.”

Donetsk regional governor Pavlo Kyrylenko said on Monday that more than 60% of the infrastructure in the city of Bakhmut, which has been the site of intense fighting, is partially or fully destroyed.

“Russia is constantly shelling Bakhmut’s infrastructure. The enemy is keeping on scorched earth tactics,” he said.

Ukraine’s eastern military command spokesman Serhiy Cherevaty also said that the Bakhmut and Avdiivka areas in Donetsk remain the sites of the heaviest hostilities. He reported that there were 225 shellings from artillery and tanks in the Bakhmut area on Monday alone.

Meanwhile, Ukraine’s military said dozens of towns in the Luhansk, Donetsk, Kharkiv, Kherson and Zaporizhzia regions were shelled by Russian forces.

In the Kherson region, Russia shelled populated areas along the right bank of the Dnieper River, Ukraine’s military said.

Ukraine’s President Volodymyr Zelenskiy has said fighting in the eastern regions of Bakhmut, Kreminna and other areas in Donbas are “difficult and painful” for Ukrainian troops.

Donetsk regional governor Pavlo Kyrylenko added that more than 60% of the infrastructure in the city of Bakhmut has been partially or fully destroyed in a update on Monday.

Despite the fighting, Ukraine’s foreign minister proposed to hold a peace summit by the end of February – preferably at the United Nations with its secretary general, António Guterres, as a possible mediator.

• Moscow has accused Ukraine of a deadly attack on an airbase that killed three Russian servicemen on Monday. Russia’s defence ministry claimed a Ukrainian drone was shot down on the approach to Engels base located about 300 miles away from the Ukrainian border but falling debris killed three service personnel. The Ukrainian government made no comment on the reported attacks.

• Ukraine’s military said dozens of towns in the Luhansk, Donetsk, Kharkiv, Kherson and Zaporizhzia regions were shelled by Russian forces. In the Kherson region, Russia shelled populated areas along the right bank of the Dnieper River, Ukraine’s military said. Ukraine’s President Volodymyr Zelenskiy said the frontline in Bakhmut, Kreminna and other areas in Donbas “now require maximum strength and concentration” in his Monday night address.

• Zelenskiy said power shortages are persisting, with nearly nine million people remaining without electricity. “Shortages persist. Blackouts are continuing,” he said in his Monday night video address. “But the numbers and the length of the blackouts are gradually decreasing.”

• Ukraine should fulfil Moscow’s proposals for settlement for its own good or the Russian army will decide, Russia’s foreign minister has said. “Our proposals for the demilitarisation and denazification of the territories controlled by the regime, the elimination of threats to Russia’s security emanating from there, including our new lands, are well known to the enemy,” state news agency Tass quoted Sergei Lavrov as saying late on Monday. “The point is simple: fulfil them for your own good. Otherwise, the issue will be decided by the Russian army.”

• Russian President Vladimir Putin hosted leaders of other former Soviet states in St Petersburg on Monday. In televised remarks Putin said threats to the security and stability of the Eurasian region were increasing. “Unfortunately challenges and threats in this area, especially from the outside, are only growing each year,” he said. “We also have to acknowledge unfortunately that disagreements also arise between member states of the commonwealth.”

• Ukraine’s foreign minister said Kyiv is aiming to have a peace summit by the end of February. Dmytro Kuleba suggested that the UN’s secretary general, António Guterres, could be the possible mediator for peace talks with Russia, though Russia could only be invited if the country faced a war crimes tribunal first. “The United Nations could be the best venue for holding this summit, because this is not about making a favour to a certain country. This is really about bringing everyone on board,” he said.

• Zelenskiy also said he sought India’s help with implementing a “peace formula” in a phone call with prime minister Narendra Modi on Monday. “I had a phone call with PM Narendra Modi and wished a successful G20 presidency,” Zelenskiy wrote on Twitter. “It was on this platform that I announced the peace formula and now I count on India’s participation in its implementation.” The Indian government said in statement late on Monday that Modi “strongly reiterated” his call for an immediate end to hostilities in Ukraine and conveyed India’s support for any peace efforts.

• Russia’s FSB security service said a Ukrainian four-person “sabotage group” was “liquidated” while trying to enter the Bryansk region on Sunday, Russian state media reported. The alleged saboteurs were armed with foreign-made guns and four improvised explosive devices, the FSB said. There was no immediate comment on the incident from Ukraine.

• Ukraine has called for Russia to be removed as a permanent member of the security council. The foreign ministry said Russia had illegally occupied “the seat of the USSR in the UN security council since the break-up of the Soviet Union in 1991, and that its three-decade presence in the UN has been “marked by wars and seizures of other countries’ territories”.

• A video has emerged allegedly shows members of the private Russian mercenary company, Wagner Group, calling the Russian armed force’s chief of general staff a “piece of shit”. Bellingcat’s Christo Grozev reports that Yevgeny Prigozhin, the Russian businessman and founder of Wagner Group, said he has “nothing to say about this video”, which Grozev writes means the Putin ally is essentially endorsing the attack on Gerasimov.
