Russian forces intensify offensive near Konstantinovka and Slovyansk

Russia's military offensive along the Ukrainian front accelerated in late May and early June following a months-long stalemate. The main advances have been concentrated in a few sectors—primarily around the city of Konstantinovka and near Slovyansk and Kramatorsk. Despite Putin's claims of victory, Russia is unlikely to capture the Kramatorsk agglomeration by 2026.

Russia's military offensive along the Ukrainian front has intensified in late May and early June, ending a months-long stalemate. The most significant advances have occurred in the city of Konstantinovka in the southern part of the Kramatorsk agglomeration, where Ukrainian defences proved weak and Russian forces managed to penetrate the city centre from two directions.

Putin's claims versus reality

Vladimir Putin has claimed that "there is no place where the Russian army is not advancing," yet in reality Russian military gains are concentrated in only a few areas. Fighting continues east of Slovyansk and Kramatorsk along the south bank of the Siverskyi Donets River and in the Siverskyi Donets–Donbas canal region, but Russian advances remain modest on other fronts.

Zaporizhzhia and other fronts

Russian pressure has also resumed in the eastern part of Zaporizhzhia Oblast, where Ukrainian counteroffensives had halted Russian advances for several months. No significant breakthroughs are occurring on other sections of the front, and in many locations the situation remains virtually static.

2026 outlook

Military analysts assess that the Russian army is unlikely to capture the Kramatorsk agglomeration and adjoining areas of Donetsk Oblast by 2026. Although the current situation is difficult for Ukraine, past experience shows that Ukraine has been able to stabilise the front even after initial Russian breakthroughs.
