Russian special forces walked miles inside of a gas pipeline to strike Ukrainian units from the rear in the Kursk region, Ukraine’s military and Russian war bloggers reported, as Moscow moves to recapture parts of its border province that Kyiv seized in a shock offensive.

Ukraine launched a daring cross-border incursion into Kursk in August, in what marked the largest attack on Russian territory since the Second World War.
