Ukrainian forces advance 15 km behind Russian lines in Kupiansk sector via underground routes

Situation Overview

On 22 October 2026, Ukrainian forces in the Kupiansk sector advanced more than 15 km behind Russian lines through underground utility routes as part of the Veles underground counteroffensive operation in Ukraine’s Kharkiv region. The Khartiia Corps of Ukraine’s National Guard said the operation combined an underground offensive with surface actions and drone strikes to prevent Russian forces from reaching the rear of Kupiansk. The Khartiia Corps commander, Brigadier General Ihor Obolenskyi, said Russian forces intended to use gas pipelines to infiltrate and that Ukrainian units moved underground to anticipate and master those tactics. The Khartiia Corps reported that more than 30 Russian personnel were taken prisoner and that the enemy suffered more than 100 casualties. No specific market or infrastructure damage figures were reported in the account.

Geopolitical Implications

   Reported use of underground utility routes and gas-pipeline infiltration concepts shows continued tactical innovation aimed at disrupting rear-area access on the Kupiansk front.
