Other MoA event in Kostyantynivka area, Ukraine on Sun 14th June 2026

The main Ukrainian stronghold in eastern Kostyantynivka has now come under operational encirclement by Russian forces.

After Ukrainian forces mostly withdrew from the western suburbs, Russian forces managed to break through Ukrainian defences in the so-called "Historical Centre" of northern Kostyantynivka, reaching the highway running through the city from the northeast, thereby blocking the last escape route for Ukrainian forces stationed further east. 

This corridor remains a grey-zone, where Russian and Ukrainian soldiers hold overlapping positions, however it will be difficult to withdraw Ukrainian forces from the eastern part of the city now. 

Elsewhere, Russian forces continue their assault operations, with soldiers infiltrating into the Novoselivka District in the northwestern part of the city. Russian DRGs are already operating on the highway into Kostyantynivka, however Ukraine continues to funnel additional reinforcements in, likely to secure withdrawal routes. Supply is now being carried out mostly with UAVs and ground drones. 

Meanwhile, heavy fighting continues near the railway station, the city cemetery, the northern private sector, Lomonosova Street (northwestern suburbs), and the former chemical plant. The situation remains critical for Ukraine as the remaining defences in the city collapse.
