Ukraine claims control of Russian logistics hub, seeks to cut more supply lines

Ukraine claimed full control of Russia's eastern logistics hub Lyman, its most significant battlefield gain in weeks, setting the stage for further advances aimed at cutting Moscow's supply lines to its battered troops to a single route.

The stinging setback for Russian President Vladimir Putin was delivered after he proclaimed the annexation of four regions covering nearly a fifth of Ukraine on Friday, an area that includes Lyman. Kyiv and the West have condemned the proclamation as an illegitimate farce.

NATO Secretary General Jens Stoltenberg said the capture of the town, where Ukrainian flags were raised over civic buildings on Saturday, demonstrated that Ukraine is capable of dislodging Russian forces and showed the impact Ukraine's deployment of advanced Western weapons was having on the conflict.

Ukrainian President Volodymyr Zelenskiy said on Sunday that the success of the country's soldiers was not limited to the recapture of Lyman.

Ukraine forces have liberated the small Arkhanhelske and Myrolyubivka settlements in the Kherson region as well, he said.

Ukraine's Interfax agency reported that according to Serhiy Cherevatyi, spokesman for the Ukrainian Eastern Group of Forces, Ukraine's forces recaptured Torske, a small village in the Donetsk region, about 15 km (9 miles) east of the now liberated Lyman.

Reuters was not able to immediately verify the reports.

Russia's defence ministry said on Saturday that it was pulling troops out of the Lyman area "in connection with the creation of a threat of encirclement".

It did not mention Lyman in its daily update on fighting in Ukraine on Sunday, although it said Russian forces had destroyed seven artillery and missile depots in the Ukrainian regions of Kharkiv, Zaporizhzhia, Mykolaiv and Donetsk.

Russian forces had captured Lyman from Ukraine in May and had been using it as a logistics and transport hub for its operations in the north of the Donetsk region. Its recapture by Ukrainian troops is Russia's largest battlefield loss since Ukraine's lightning counteroffensive in the northeastern Kharkiv region in September.

Control over Lyman could prove a "key factor" in helping Ukraine reclaim lost territory in the neighbouring Luhansk region, whose full capture Moscow announced in early July after weeks of grinding advances, Luhansk governor Serhiy Gaidai said.

Lyman's operational importance was due to its command over a road crossing over the Siverskyi Donets River, behind which Russia has been attempting to consolidate its defences, Britain's Ministry of Defence said.

"Thanks to the successful operation in Lyman we are moving towards the second north-south route...and that means a second supply line will be disrupted," said reserve colonel Viktor Kevlyuk at Ukraine's Centre for Defence Strategies think tank.

"And in that case, the Russian group in Luhansk and Donetsk could only be supplied strictly through (Russia's) Rostov region," Kevlyuk told media outlet Espreso TV.

Annexed regions

The areas Putin claimed as annexed just over seven months into Russia's invasion of its neighbour - Donetsk and Luhansk plus Kherson and Zaporizhzhia in the south - are equal to about 18% of Ukraine's total surface land area.

Russia's parliament is to consider on Monday bills and ratification treaties to absorb the regions, the speaker of Russia's lower house of parliament, Vyacheslav Volodin said.

A pomp-filled Kremlin signing ceremony with the regions' Russian-installed leaders on Friday failed to stem a wave of criticism within Russia of how its military operation is being handled.

Putin ally Ramzan Kadyrov, the leader of Russia's southern Chechnya region, on Saturday called for a change of strategy "right up to the declaration of martial law in the border areas and the use of low-yield nuclear weapons." Washington says it would respond decisively to any use of nuclear weapons.

Other hawkish Russian figures on Saturday criticised Russian generals and Russian Defence Minister Sergei Shoigu on social media for overseeing the setbacks but stopped short of attacking Putin.

The United States was "very encouraged" by Ukrainian gains, Defence Secretary Lloyd Austin said on Sunday, while NATO's Stoltenberg said the fall of Lyman demonstrated the effectiveness of Western weapons in the conflict.

Pope Francis on Sunday made an impassioned appeal to Putin to stop "this spiral of violence and death" in Ukraine and also called on Zelenskiy to be open to any "serious peace proposal".

Zelenskiy said on Friday that peace talks with Russia while Putin was still president would be impossible. "We are ready for a dialogue with Russia, but with another president of Russia," he said.
