Russia has begun carrying out sabotage operations against Danish companies supplying Ukraine, after concluding that broader disruption efforts failed to curb Western military support, a Danish intelligence official said Wednesday. The official, from Denmark’s PET security and intelligence service, told a homeland security conference in Copenhagen that what began as planning in the spring escalated into action in early summer, reflecting a significant escalation in Moscow’s hybrid warfare campaign. Russia is increasingly using untrained proxies, including vulnerable people recruited via Telegram and social media, starting them with low-threshold tasks like reconnaissance before escalating to actual sabotage, PET said. Moscow has repeatedly denied involvement in sabotage or hybrid operations.
