**Deck**: Russian forces have made fresh gains toward Slovyansk, Kramatorsk, Kostyantynivka and Dobropillya in Donetsk Oblast, advancing through forests, villages and industrial areas while stepping up drone and artillery strikes. The offensive is testing Ukraine’s main Donbas defensive belt and bringing cities like Kramatorsk closer to the front line.

Russia’s latest advances around Slovyansk, Kramatorsk, Kostyantynivka and Dobropillya are putting Ukraine’s main defensive belt in Donetsk under some of the heaviest pressure since the fall of Avdiivka, moving key cities closer to the reach of frontline fire.

Over the past three weeks, Russian units have continued offensive operations on multiple axes in northern and central Donetsk Oblast, according to detailed frontline reporting. In the Slovyansk and Kramatorsk directions, Russian forces consolidated control of forested areas west of Kryva Luka, gained a foothold in the village of Pyskunivka, and cleared Ukrainian positions north of Brusivka. Additional assault groups pushed through industrial zones toward Petrivka, Ivanivka and Oleksandrivka, while other units exploited recent gains south of the Siverskyi Donets canal to advance toward Novoselydivka and Kalynove.

To the south and west, Russia has effectively taken control of most of Kostyantynivka, with only fighting reported in its outer streets, and has shifted focus to flanking moves toward Druzhkivka. Further south again, in the Dobropillya direction, Russian troops have recaptured most of Kucheriv Yar and adjacent forest positions, using them as a springboard for deeper reconnaissance and sabotage team infiltrations toward nearby settlements.

For civilians in Slovyansk, Kramatorsk, Druzhkivka and surrounding towns, this grinding advance is closing the distance between their homes and the front line. Residents face more frequent artillery, missile and drone attacks, with evacuation routes and relief convoys operating under growing risk. A Ukrainian channel tracking Kramatorsk’s situation overnight underscored a sense of mounting proximity to active combat, even before any formal declaration that the city has become part of the direct frontline zone.

On the battlefield, Russia’s progress is gradual but costly, relying heavily on drones and guided munitions to wear down Ukrainian positions before infantry and armored pushes. Following the advance beyond the Siverskyi Donets canal and deeper into Kostyantynivka’s urban fabric, Russian drone operators have been able to move forward and now launch near-constant strikes across the “fortress belt” of fortified settlements that Ukraine has spent years building. This forward positioning magnifies the impact of loitering munitions and cheap first-person-view drones against Ukrainian trenches, logistics, and rear-area movements.

Strategically, the campaign aims to unpick a chain of strongpoints protecting the larger Donbas agglomeration. If Russian forces can fully secure Kostyantynivka and gain firmer control of heights and road junctions around Druzhkivka, they will be better placed to threaten Kramatorsk from multiple directions. At the same time, sustained pressure in the Dobropillya sector and around Slovyansk stretches Ukrainian reserves and complicates any effort to stage a coherent defensive line.

The human and operational stakes are tightly intertwined. Every kilometer Russia gains in the forests around Kryva Luka or in villages like Pyskunivka does not just redraw a map; it exposes more Ukrainian communities to artillery fire and makes it harder to rotate exhausted units out of the line. For Ukrainian commanders, the question is shifting from whether Russia can approach Kramatorsk and Slovyansk to how much ground Kyiv can trade while preserving combat power and access to key logistics hubs.

Signals to monitor in the coming days include confirmed control of remaining neighborhoods in Kostyantynivka, evidence of Russian attempts to interdict major roads and rail links feeding Kramatorsk, and any visible Ukrainian efforts to establish fallback positions west of the current fighting. Increased evacuation orders or public guidance from Ukrainian authorities for residents of Kramatorsk and Slovyansk would also mark a significant step in acknowledging that this part of the Donbas is moving closer to an active frontline.
