Volodymyr Zelensky has called for world leaders to ensure Russia does not use nuclear weapons in response to its continued setbacks in Ukraine.
The Ukraine president claimed that Russian officials have begun to "prepare their society" for the possible use of nuclear weapons even if they are not yet ready to use them. He said action was needed now because Russia's threats were a "risk for the whole planet".
Moscow, he told the BBC, had "made a step already" by occupying the Zaporizhzhia nuclear power plant, Europe's largest nuclear station which Russian president Vladimir Putin is trying to turn into Russian property. He said around 500 Russian troops were at the plant, although the Ukrainian staff still operate it.
