Vladimir Putin wants the world to believe the road to the rest of the Donetsk region is wide open. Sitting down with his top military brass, including Chief of the General Staff Valery Gerasimov, the Russian president boldly claimed his troops completely captured Kostiantynivka. He called it a key that unlocks the remaining heavily fortified Ukrainian strongholds of Sloviansk and Kramatorsk.
But if you look past the official Kremlin briefings, a much messier, highly contested reality emerges.
Ukrainian President Volodymyr Zelenskyy fired back immediately, calling the claim just another Russian lie. He even mocked the Russian leader, suggesting that if Putin truly controlled the industrial city, he should have no problem meeting there face-to-face for peace talks. The Ukrainian General Staff and the Institute for the Study of War back this up, confirming that intense urban combat is still raging.
While Moscow attempts to project a massive breakthrough, Russian forces have instead unleashed a devastating wave of aerial strikes on civilian centers across Ukraine, including a horrific guided bomb attack on an apartment building in Sumy.
The Battle for the Fortress Belt
Kostiantynivka isn't just any city. It serves as the southernmost anchor of Ukraine's vital defensive agglomeration in the east. For over a decade, Ukrainian forces transformed this industrial hub into a heavily fortified stronghold.
Moscow's military planners know that securing this city is vital if they ever want to realize their goal of taking the entire Donbas. If Russian forces actually manage to consolidate control here, they gain a major logistics and transportation hub. They can use it to push north along the main axis of their campaign.
Right now, that hasn't happened.
Military reports show that while Russian troops managed to infiltrate parts of the city over the last month, the presence is largely limited to small, scattered sabotage groups. Ukrainian units, specifically elements of the 19th Army Corps, are actively engaging these units in brutal, street-by-street clearing operations. The situation on the ground remains incredibly fluid, but a total Ukrainian collapse in the city is simply not reality.
Cognitive Warfare and Fabricated Victories
Why would the Kremlin claim a total victory when the fighting is still going on? It's a calculated part of a broader psychological strategy.
Independent military analysts point out that senior Russian officials have been exaggerating battlefield achievements nearly every month. The goal is simple. Moscow wants to convince Western backers that Ukrainian resistance is futile and that Russian momentum is unstoppable.
The underlying data tells a different story. The Russian spring-summer offensive has slowed down compared to previous campaigns. It's costing Moscow massive amounts of personnel and hardware to achieve even minor tactical advances. Fabricating an information victory out of a bloody, unfinished urban battle helps paper over these operational difficulties.
Deadly Strikes Beyond the Frontline
As the information war peaked over the status of Kostiantynivka, the physical war continued to take a terrible toll on ordinary civilians. Zelenskyy fiercely condemned a series of Russian strikes using guided aerial bombs and drones targeting cities far from the immediate eastern front.
In the northern city of Sumy, a guided bomb tore through the center of an apartment building. The attack killed four people, including a child, and left dozens of others injured as rescue crews frantically dug through the rubble. Similar drone and missile strikes hit Zaporizhzhia, Kharkiv, and the Dnipro region.
These sustained aerial assaults underscore the heavy pressure Ukraine faces. Kyiv continues to urge its global partners, especially the United States and European nations, to step up air defense deliveries and tighten economic sanctions on Russia's energy and financial sectors.
For now, the fortress belt holds. Moscow's claims of a decisive breakthrough remain entirely premature, but the sheer intensity of the fighting suggests the pressure on Ukraine's eastern flank is nowhere near its end.
