As Russia made progress in revising its nuclear policy amid its war with Ukraine, North Korea vowed to never give up its own nuclear weapons despite demands from the West.

President Vladimir Putin warned the West on Wednesday that Russia could use nuclear weapons if it was struck with conventional missiles, and that Moscow would consider any assault on it supported by a nuclear power to be a joint attack.

Ukrainian President Volodymyr Zelensky charged Wednesday before the United Nations that Russian leader Vladimir Putin is planning to attack nuclear power plants in his country, warning of catastrophic consequences.

Ukrainian President Volodymyr Zelenskiy's chief of staff, Andriy Yermak, criticized Russia's recent changes to its nuclear policy, asserting it shows Moscow's reliance on nuclear threats to exert global influence.

According to Kremlin spokesman Dmitry Peskov, amendments to the nuclear doctrine have been prepared and will be legally formalized soon in Russia. He stated that the evolving situation in Ukraine necessitated a change in the doctrine.
