Russian forces infiltrate most of Kostiantynivka as Ukraine rotates troops

Front‑line reports indicate that Russian forces have penetrated the majority of Kostiantynivka, a city in the Donetsk region, as part of a renewed push to regain the initiative in the eastern Ukraine conflict. Ukrainian military statements confirm that combat units are engaged in intense urban fighting, with both sides exchanging artillery and small‑arms fire while attempting to secure key infrastructure and supply routes within the city limits.

The infiltration comes amid broader Russian efforts to re‑establish momentum after recent setbacks on the front, and analysts note Kostiantynivka’s strategic position near the Donets River and major road networks. Ukrainian authorities have not released casualty figures, but local officials warn of significant civilian displacement and damage to residential areas. The situation remains fluid, with both sides reporting continued operations to either consolidate control or mount counterattacks, underscoring the ongoing volatility of the conflict in the region.
