The Security Council met behind closed doors to discuss Moscow’s claim, first made public Sunday, that it believed Ukraine would explode a crude nuclear device in the war zone and blame Russian forces for it."Ukraine has all the reasons to do so because we know that Zelensky regime wants to avoid first of all defeat, secondly wants to involve NATO in a direct clash with Russia," he said, referring to Ukrainian President Volodymyr Zelensky.Such a scheme is "very dangerous but will be profitable for the Zelensky regime to remain in power," Polyanskiy said.He said that inspectors from the International Atomic Energy Agency were on the way to Ukraine after being invited by Kyiv to inspect its nuclear facilities.The United States, France and Britain rejected Shoigu's claim in a joint statement, suggesting it was a scheme by Moscow to ratchet up the war."
