🇷🇺🇪🇺🪖⚡️ — Russia has warned NATO that it would be prepared to use its “entire arsenal,” including nuclear weapons, if the alliance attempted to isolate Kaliningrad from the rest of Russia, Reuters reports.

In a diplomatic note seen by Reuters, Moscow accused NATO of a “dangerous and reckless course” carrying “high risks” of direct conflict and warned of possible strikes on NATO decision-making centers.

NATO rejected the warning, saying its activities pose no threat to Russia and urging Moscow to end its invasion of Ukraine and its “irresponsible nuclear rhetoric.”

Russian embassies in several European countries also accused NATO of escalating tensions, while Kremlin spokesman Dmitry Peskov described the messages as warnings to “hotheads in Europe.”
