Sergey Naryshkin, the head of Russia's Foreign Intelligence Service (SVR), has issued a stern warning to NATO countries against aiding Ukraine in conducting long-range strikes into Russian territory with Western weapons. In statements reported by RIA news agency and National Defence magazine, Naryshkin emphasized that any such attempts by NATO members would 'not go unpunished.' This warning comes amidst heightened tensions between Russia and NATO over the ongoing conflict in Ukraine. Additionally, Naryshkin mentioned updates to Russia's nuclear doctrine, which now excludes the possibility of defeating its army on the battlefield, signaling a potential escalation in the region's military dynamics.
