US President Joe Biden has warned that the risk of a nuclear “Armageddon” is at its highest level for 60 years.
Mr Biden said that Russian President Vladimir Putin was “not joking” when he warned that Moscow would use “all means we have” to defend Russian territory. Mr Putin has also said that the US created a “precedent” by using nuclear weapons in World War Two.
But analysts suggest Mr Putin’s words should probably be interpreted as a warning to other countries not to escalate their involvement in Ukraine, rather than signalling any desire to use nuclear weapons.
