Ukrainian forces reportedly advanced over 15 kilometers through underground communications behind Russian lines on the Kupiansk front. The grouping, commanded by the National Guard's 'Khartia' unit, combined underground advances with surface actions and drone strikes, preventing Russian forces from entering Kupiansk's rear.

The operation resulted in over 30 Russian soldiers being taken prisoner, with enemy losses estimated at over 100. The report was shared by Ukrinform via Facebook and YouTube.
