Polish authorities have detained eight individuals in connection with an alleged Russian-linked sabotage plot, revealing a larger operation involving espionage and attempts to smuggle explosives into Ukraine. This comes after the arrest of over 55 suspects in recent months, highlighting concerns about Russian hybrid warfare tactics in the region. Romanian intelligence services have also intercepted a similar sabotage attempt aimed at critical infrastructure, and both nations are collaborating to counteract potential threats. The ongoing investigations indicate a coordinated effort by Russian intelligence to undermine security in Eastern Europe.
