Zelenskiy denies Russian capture of key eastern city Kostiantynivka

Ukraine still controls the strategically important eastern city of Kostiantynivka, President Volodymyr Zelenskiy and the General Staff said on Saturday, rejecting Russian claims that it has been captured.

Russia's military ignored Zelenskiy's assertions, said it was mopping up remaining pockets of resistance and offered to exchange the remains of dead servicemen.

Russian military commanders told President Vladimir Putin on Friday that Moscow's forces had taken control of Kostiantynivka, a target that Moscow has long sought in its advance through the Donetsk region.

"Of course, that is not true. It is just another Russian lie, an attempt to generate some kind of a news story," Zelenskiy said on X.

"If Kostiantynivka were under Russian control, then perhaps (Russian President Vladimir) Putin would have no problem meeting me there to find a diplomatic way to finally end this war," he added.

The General Staff also said Kostiantynivka remained under the control of Ukrainian forces.

"Military units and subunits of the 19th Army Corps of the Eastern Grouping continue to conduct defensive operations on designated lines within the town and on its approaches," it said in a statement.

Kremlin spokesman Dmitry Peskov, speaking on Russian radio, mocked Zelenskiy's suggested meeting, saying Kostiantynivka was already a part of Russia and the Kremlin's invitation for Zelenskiy to meet Putin in Moscow still stood.

Zelenskiy last month wrote to Putin seeking face-to-face talks as a step towards peace, but has long rejected any meeting in the Russian capital.

Proposal to exchange remains of soldiers

A Russian Defence Ministry statement said: "With the liberation of the city of Kostiantynivka by Russian troops and the establishment of full control over it, the Russian side is ready to carry out a humanitarian action to hand over the bodies of deceased Ukrainian servicemen in this settlement."

The statement on Telegram said Moscow was proposing a six-hour ceasefire on Monday around the town to permit an exchange and gave Ukraine until noon (0900 GMT) on Sunday to reply.

Russian state news agency TASS quoted a commander in the town, identified by call sign Agalu, as saying that clearing operations in the town were "coming to an end" and Russian troops were already setting up battle positions.

Kostiantynivka is the southernmost of four key settlements that form a defensive line central to Ukraine's effort to hold the heavily industrialised Donetsk region.

Analysts say capturing the city would give Russian forces a foothold from which to push north along the defensive belt, now the main axis of their campaign.

Russia's military has for some time reported controlling parts of Kostiantynivka, one of several heavily fortified cities that make up Ukraine's so-called "fortress belt" in Donetsk.

Aside from Kostiantynivka, Russia's Defence Ministry quoted another commander as saying heavy fighting was continuing around Lyman, a town further northeast.

The ministry also said its forces had taken five villages in eastern Ukraine: Shyikivka, Novyi Myr, Cherneshchyna and Druzhelyubivka in Kharkiv region, and Vasylivka in Donetsk region.
