FSB says it foiled Ukrainian-linked sabotage plot on North Caucasus gas pipeline

Russia's FSB claims it prevented a sabotage attack on a gas pipeline in the North Caucasus, arresting a Ukrainian national who allegedly coordinated with a Ukrainian Security Service officer since 2024. The claim is unverified and part of an ongoing pattern of cross-border sabotage accusations. It signals continued low-level asymmetric conflict targeting energy infrastructure.
