President Vladimir Putin has called for "severe" responses to what he called foreign agents who aim to destabilize Russia by helping Ukraine fight Moscow’s ongoing invasion. In a video address to Russian security forces who mark their day on December 20, Putin said, "foreign special agents' attempts to destabilize the political and social situation in Russia must be severely stopped." In the video posted on the Kremlin's website, Putin accused the Ukrainian government of using the "direct support of foreign special services." Several sabotages on Russian railroads and drone attacks attributed to Ukraine have been reported since Russia launched its invasion.
