US President Joe Biden has warned that if Vladimir Putin decides to use a nuclear weapon in Ukraine, the world faces the prospect of 'Armageddon'.
The leader of the US made the comments at a fundraiser in New York on Thursday evening, saying that the world was the closest it's been to catastrophe for the last six decades.
He was referring to the Cuban missile crisis of 1962, when the US and the Soviet Union clashed over missile testing in the Central American country.
