Recent reports from the DeepState project indicate that Russian military units are actively working to establish a buffer zone along the border in the Sumy region of Ukraine. This development follows initial reconnaissance efforts by Russian forces to assess vulnerabilities in the area.
The village of Hrabovske marked the beginning of these advances, with ongoing pressure now observed near Myropilske, where the latest updates show enemy movements. Analysts have identified approximately 150 square kilometers of newly established control and infiltration zones, denoted in red and gray, along the Sumy border.
Ukrainian defense forces are aware of the adversary’s intentions and are monitoring the situation closely, striving to counter the expansion of Russian control.
In March 2026, DeepState analysts reported increased Russian military activity near the Sumy border, emphasizing efforts to extend control in border villages. Notably, on March 13, Russian forces advanced south of the village of Yablunivka within the Yunakivka community in Sumy Oblast. Further incursions were recorded on April 3, near the village of Riasne, adjacent to the Russian border.
Russian military forces are intensifying their operations along the Sumy border, establishing a buffer zone that has expanded to approximately 150 square kilometers. Ukrainian defense forces remain vigilant and are actively countering these developments.
