Kyiv, Ukraine CNN —
Ukraine’s presence in Russia’s Kursk region has deteriorated sharply, with the Russian advance threatening Kyiv’s [sole territorial bargaining counter](https://www.cnn.com/2025/02/07/world/ukraine-kursk-trump-ceasefire-talks-intl/index.html)
at a crucial time in the war.
Military bloggers from both sides say Ukraine is on the back foot, while Ukraine’s army says Russian forces used a gas pipeline to launch a surprise raid in one area. Russia’s defense ministry on Sunday said its forces had captured four settlements in a couple of days.

in August, swiftly capturing territory in what was the first ground invasion of Russia by a foreign power since World War II.
As well as capturing land that could potentially be swapped for Russian-occupied territory, the campaign aimed to divert Moscow’s resources from the front lines in the east.
But since then, Ukraine has struggled to hold onto its territory in Kursk and faces a fundamentally transformed diplomatic picture, with United States President [Donald Trump](https://www.cnn.com/2025/03/08/europe/ukraine-war-us-policy-shifts-analysis-intl/index.html)
piling pressure on Kyiv to agree peace by halting US military aid and intelligence sharing.
Russia’s defense ministry on Sunday said troops took back the settlements of Malaya Loknya, Cherkasskoye Porechnoye and Kositsa from Ukrainian forces.
“The lid of the smoking caldron is practically closed,” Dmitry Medvedev, the former Russian president who is now the deputy chairman of the country’s Security Council, said on Sunday of Russian advances in Kursk. “The offensive continues. Carry on!”
Ukrainian and Russian military bloggers warn Kyiv’s hold on the region is more tenuous than ever, with Russian troops backed by North Korean forces launching incessant attacks.
CNN is unable to independently verify battlefield reports but such bloggers have previously provided an accurate account of the fighting.

Gas pipeline surveillance stepped up
------------------------------------
The latest reports suggest Russia is targeting Sudzha, a town on the border, in an attempt to cut off a key logistical supply route to Ukraine’s forces inside Kursk.
Yuriy Butusov, a Ukrainian military blogger, said Russian forces had on Saturday entered Sudzha along a gas pipeline.
“The Russians used a gas pipeline to deploy an assault company undetected by drones and wedged themselves into our combat formations,” Butusov wrote. He added that the pipeline was now under reinforced surveillance and that Moscow’s troops there were being “eliminated.”
However, Butusov warned that Russian and North Korean troops in Kursk region are at a “significant advantage in strength” and are “attacking continuously.”
Some 12,000 [North Korean troops](https://www.cnn.com/2025/02/26/asia/ukraine-war-north-korean-troops-russian-ships-hnk-intl/index.html)
have been deployed to Kursk, and their arrival has bolstered Russia’s offensive operations inside its own borders. Should Russia retake all of Kursk it could potentially pour its manpower into eastern Ukraine.
“It’s hard, but we’re working,” one Ukrainian serviceman told CNN. “The Koreans keep coming.”
An unofficial Russian military blogger gave a similar account in the town of Sudzha, claiming that around 100 Russian soldiers had infiltrated the settlement after sneaking in via the pipeline – a move which he said was made possible after Kyiv shut off Russian gas supplies to the European Union via Ukraine on January 1.
Ukraine’s military said on Telegram that the Russian forces had gained a “foothold” on the outskirts of Sudzha, adding: “Currently, the Russian special forces are being identified, blocked, and destroyed. The enemy losses in the Sudzha area are very significant.”
‘Critical’ logistics situation
------------------------------
Russian forces are attacking Sudzha from several directions, according to Yuriy Kotenok, a Russian military blogger.
“Any movements of the enemy in this area are detected by our drones and the enemy’s personnel and equipment are being struck,” he wrote on Telegram.
Kotenok also claimed that there is “information” that Ukraine is going to withdraw from the Kursk region, “based on the current situation.”
Sternenko, a Ukrainian blogger, said the logistics situation was “already critical.”
Another difficulty was the “poor conditions of the roads,” Sternenko said. With spring bringing warmer temperatures, the ground will thaw, making roads muddier and even harder to traverse, he said. “All these circumstances are very favorable to the Russians,” he added.
Kyiv’s fear is that Russia’s gains could cut off supplies to Ukrainian troops in Kursk. In a major report last month, the Institute for the Study of War, a US-based conflict monitor, estimated that Ukraine has at most 30,000 troops stationed in the region.
The Kursk incursion was embarrassing for Moscow and raised questions over its ability to protect its own borders. Russian President Vladimir Putin has since repeatedly pledged his forces would regain full control of the region.
Kyiv has lost about half of the territory it once occupied in Kursk.
In the face of Russia’s gains, some Ukrainian bloggers have suggested that the Kursk incursion may have exhausted its strategic value.
“I didn’t think I would ever say this. But maybe it’s time to ‘close the shop’ from the Kursk direction. It’s hard for our guys there,” said Serhii Flesh. “As a diversion of enemy resources, I think this operation has long since justified itself. As a political bargaining card, it is now questionable.”
