Russian Forces Enveloping Kostyantynivka: A Critical Junction in Donbas

Tue Jun 23 2026 14:04:40 GMT+0000 (Coordinated Universal Time)

Russian troops now occupy Kostyantynivka, threatening Ukraine's eastern defence and opening a path to the remaining strongholds in Donbas.

In a steady advance, Russian forces have infiltrated the strategic city of Kostyantynivka, placing it under the so‑called "grey zone" and threatening Ukraine’s last bastions in the east. Local commanders insist the situation is controlled, yet about 130 Russian soldiers remain inside the city, making it a focal point for both sides. Drone units on both sides are mobilizing – the Russians using basic air drones to scour for Ukrainian launch sites, while Ukrainian pilots target Russian artillery and supply lines. If the city falls, the Kremlin’s key objective of full Donbas control inches closer, while Ukraine’s logistical lines will be severely strained. The urgency of the conflict is underscored by the scarcity of fuel in Crimea and the ongoing cross‑border attacks on Russian infrastructure.

Russian Troops Envelop Kostyantynivka

Russian forces have pushed into the eastern Ukrainian city of Kostyantynivka, turning the area into a "grey zone" where control is contested. Ukrainian commanders say the situation remains under control, but about 130 Russian soldiers are still inside the city, according to Brig. Gen. Oleksandr Bakulin.

The city serves as a gateway to the Donbas region. Its capture would allow Russian troops to advance toward Kramatorsk and Sloviansk – the last Ukrainian-held strongholds in the east – and bring the Kremlin’s goal of full Donbas conquest closer to reality.

Russian forces have advanced from the south and also moved to the northern outskirts, reportedly encircling Ukrainian units. Ukrainian drone pilots report that Russian airborne units are now operating near city limits, making it easier for them to conduct surveillance and target Ukrainian launch sites.

According to a Ukrainian drone pilot, Russian drones – including inexpensive Chinese models – are being used to detect movements within the city, while the Russians fire artillery, multiple rocket launchers, and aircraft to pursue Ukrainian forces. The Ukrainian side has limited resources, making it difficult to expand operations and counter Russian advances.

Logistical struggles compound the crisis. Land routes to the city are constantly targeted, and large drones carrying supplies are often intercepted. The Ukrainian Defence Ministry’s “DeepState” monitoring project lists the fall of Kostyantynivka as inevitable if the current trajectory continues.

The situation is further complicated by fuel shortages in Crimea, where Russian authorities have suspended fuel sales after Ukrainian strikes cut supply lines. This shortage has disrupted Moscow’s logistics and intensified the conflict outside the front line.

The Kremlin’s propaganda effort has highlighted villages west of the city that have fallen to Russian control, diverting attention from Ukrainian attacks on Russian oil refineries and supply routes.

As the front moves, Ukrainian commanders have admitted shortages of reinforcements and a reluctance to report losses publicly. Without a change in strategy that focuses on disrupting Russian logistics and targeting pilots, the city may be lost to Russian forces, further tightening the north‑east corridor.
