Russian forces continue limited offensive operations and cross-border strikes in northern Sumy Oblast aimed at establishing a buffer zone along the border, with recent artillery, drone, and glide-bomb attacks targeting settlements near the city of Sumy itself. Independent assessments from the Institute for the Study of War indicate Russian claims of territorial gains in the area remain exaggerated, with Ukrainian units maintaining control and conducting counterstrikes that have disrupted infiltration attempts. Broader battlefield trends show Russian net territorial gains across Ukraine turning negative in recent months amid Ukrainian counteroffensives elsewhere, limiting resources available for a sustained push on Sumy. No major advances toward the city have materialized in the past 30 days.
