Ukrainian President Volodymyr Zelensky and the General Staff have categorically rejected Moscow’s assertion that Russian forces have captured the eastern city of Kostiantynivka, a key bastion in Ukraine’s so-called “fortress belt” in the Donetsk region. The denial came hours after the Russian Defence Ministry announced that General Staff chief Valery Gerasimov had informed President Vladimir Putin of the city’s alleged fall, calling it a “significant strategic success.”

Speaking on X, Zelensky dismissed the claim as “another Russian lie.” “If Kostiantynivka were under Russian control, Putin would have no problem meeting me there to find a diplomatic way to end this war,” he wrote. The Ukrainian General Staff echoed the president’s statement, insisting that units of the 19th Army Corps continue to defend the city along fixed lines within its boundaries and at its approaches. “We reject this. These are further false reports,” a General Staff spokesman told Reuters.

The Russian military has repeatedly claimed parts of Kostiantynivka under its control, but independent verification remains impossible. Analysts at the US-based Institute for the Study of War have previously flagged Moscow’s exaggerated battlefield claims, citing geolocated footage that contradicted official announcements. Russian military bloggers have also criticised the Kremlin’s repeated overstatements, noting that earlier assertions of full control proved premature.

Kostiantynivka sits on a critical route toward the last major Ukrainian-held cities in the Donbas, making it a prime target in Russia’s prolonged eastward push. Before the full-scale invasion, the city had a population of nearly 70,000; today, it is estimated to have fewer than 2,000 residents. Its capture would give Russian forces a bridgehead to advance northward, though analysts warn that further gains would likely come at a heavy cost in lives and time, resembling the gruelling sieges of other eastern cities such as Pokrovsk and Avdiivka.

The Kremlin’s announcement came just a day after Ukraine launched drone strikes on Russian oil infrastructure near Saint Petersburg, including a reported hit on an oil terminal. Russian authorities claimed to have intercepted dozens of Ukrainian drones over the city, framing the strikes as an escalation in Kyiv’s campaign against Russian energy assets.

Zelensky also addressed the ongoing shortage of Patriot missile systems, which have become a critical component of Ukraine’s air defences amid relentless Russian missile and drone barrages. In a call with German Chancellor Friedrich Merz, he emphasised the need to secure additional Patriot munitions, noting that Russia’s dwindling options for prolonging the war now centre on missile strikes. “Russia is playing its last card with missile attacks on Ukraine,” Zelensky stated. “It has no other options left to drag out the war.”

The conflicting claims underscore the fog of war that continues to shroud frontline developments. While Moscow celebrates what it portrays as a breakthrough, Kyiv insists the city remains firmly within Ukrainian hands. The dispute highlights the broader challenge of verifying battlefield reports in a conflict where both sides routinely accuse each other of spreading disinformation.
