Russia said on Wednesday its troops had broken through two fortified lines of Ukrainian defences on the eastern front, as Kyiv described the situation there as difficult and called for faster military aid ahead of a predicted Russian offensive.

The Russian Defence Ministry said the Ukrainians had retreated in the face of Russian attacks in the Luhansk region, although it provided no details and Reuters was not able to independently verify the battlefield report.

“During the offensive … the Ukrainian troops randomly retreated to a distance of up to 3 km (1.9 miles) from the previously occupied lines,” the ministry said on the Telegram messaging app.

“Even the more fortified second line of defence of the enemy could not hold the breakthrough of the Russian military.”

The ministry did not specify in which part of the Luhansk region the offensive took place. Reuters was not able to independently verify the battlefield report.

President Volodymyr Zelenskiy’s office said Ukrainian forces had repelled some Russian attacks in Luhansk but added: “The situation in the region remains difficult.”

Luhansk regional governor Serhiy Haidai said Russia was pouring heavy equipment and mobilised troops into Luhansk but Ukrainian forces were still defending the region.

“The attacks are coming from different directions in waves,” Haidai said. He added: “Those who spread the information that allegedly our defence forces have pulled back beyond the line of the administrative border (of Luhansk) – this does not correspond to reality.”

The Kremlin has intensified attacks across a swathe of southern and eastern Ukraine in recent weeks, and a major new offensive has been widely anticipated.

Russia’s main effort has been focused on the town of Bakhmut in Donetsk province adjacent to Luhansk.

The General Staff of the Ukrainian Armed Forces did not mention any significant setbacks in Luhansk in its regular morning update. It said Ukrainian units repelled attacks in the areas of more than 20 settlements, including Bakhmut and Vuhledar – a town 150 km (90 miles) southwest of Bakhmut.

Zelenskiy on Tuesday said Russia was in a hurry to achieve as much as it can with its latest push before Ukraine and its allies gather strength.

“That is why speed is of the essence,” he said as NATO defence chiefs met in Brussels for talks that continue on Wednesday. “Speed in everything – adopting decisions, carrying out decisions, shipping supplies, training. Speed saves people’s lives.”

Bakhmut’s capture would give Russia a stepping stone to advance on two bigger cities, Kramatorsk and Sloviansk in Donetsk, giving it momentum after months of setbacks ahead of the Feb, 24 first anniversary of the invasion.

“The battles are literally for every foot of Ukrainian land,” Zelenskiy said, describing the conditions on the eastern frontline in his evening address on Tuesday.

Ukrainian military analyst Oleh Zhdanov said in a YouTube video there was fighting “around every single house” in Bakhmut.

WESTERN SUPPORT
Ukraine is using shells faster than the West can make them and says it needs fighter jets and long-range missiles to counter the Russian offensive and recapture lost territory.

The United States and NATO have pledged that Western support will not falter in the face of a looming Russian offensive.

U.S. Defense Secretary Lloyd Austin said on Tuesday he expected Ukraine to launch its own offensive in the spring. He added: “Ukraine has urgent requirements to help it meet this crucial moment in the course of the war. We believe there’ll be a window of opportunity for them to exercise initiative.”

On Jan. 20 a senior U.S. administration official said Washington was advising Ukraine to hold off with a major offensive until the latest supply of U.S. weaponry is in place and training has been provided.

Representatives of the 27 European Union countries meet in Brussels on Wednesday to discuss a new batch of sanctions against Russia, which the head of the bloc’s executive said could amount to 11 billion euros ($11.8 bln) in lost trade.

German Defence Minister Boris Pistorius said supplying Ukraine with fighter jets would certainly be discussed but that it was not a focus at the moment, and added he was in favour of raising NATO’s military spending target. British Defence Secretary Ben Wallace said Western allies could help Ukraine more quickly by supporting their position on the ground rather than focusing on the provision of jets.

Russia calls the invasion a “special military operation” against security threats, and says NATO shows hostility to Russia daily and is growing more involved in the conflict. Kyiv and its allies call Russia’s actions an unprovoked land grab.

Russia holds swathes of Ukraine’s southern regions of Kherson and Zaporizhzhia, including its nuclear plant, nearly all of Luhansk and over half of Donetsk. Last year, Russia declared it had annexed the four regions in a move condemned by most United Nations members as illegal.

Russia plans to retake the settlements in the northeastern Kharkiv region that it surrendered to Kyiv last year, the head of the Russian-installed administration there said on Wednesday.

A U.S.-backed report published on Tuesday said Russia had held at least 6,000 Ukrainian children – likely many more – in camps in Crimea and Russia whose primary purpose appeared to be political re-education. Russia’s embassy in Washington said Russia accepted children who were forced to flee with their families from the shelling in Ukraine.
