US EditionRussians break into Kupiansk via gas pipeline, watchdog says
Russian troops bypassed the Oskil river using a gas pipeline from Lyman Pershyi to infiltrate Kupiansk, setting up drone positions amid ongoing Ukrainian counter-sabotage efforts.
- On September 12 and 13, 2025, Russian troops infiltrated Kupiansk in Kharkiv Oblast by moving through a gas pipeline from the occupied village of Lyman Pershyi nearby.
- This infiltration followed earlier use of pipelines as a tactic in the region, prompted by Russian efforts to bypass natural barriers like the Oskil river and gain surprise behind Ukrainian lines.
- Russian forces set up drone pilot positions in Kupiansk, while Ukrainian Defense Forces damaged and closed pipeline valves to prevent further equipment movement through the route.
- Ukrainian officials stated, "There are no Russians in Kupiansk," while fighting continued on the outskirts and the General Staff reported 395 Russian casualties, including 288 killed, in operations near the town.
- The events highlight the vulnerability of pipeline routes as infiltration paths and have led Ukrainian forces to strengthen surveillance and carry out counter-sabotage operations in and around Kupiansk.
