According to a pro-Kremlin blogger, Russian operatives walked about 9 miles inside the pipeline that Moscow had until recently used to send gas to Europe.

Footage shared on Telegram appears to show Russian soldiers crouching and moving through the pipeline in darkness toward the town of Sudzha, according to. In the video, the soldiers can be heard cursing and complaining about their commanders for sending them on the mission.

The attack occurred near a key metering facility in the Kursk region of Russia which would be key to any resumption of gas pipeline shipments via Ukraine to countries including Slovakia and Hungary
