Vladimir Putin says Russia would consider an attack from a non-nuclear state that was backed by a nuclear-armed one to be a “joint attack”, in what could be construed as a threat to use nuclear weapons in the war in Ukraine.
In key remarks on Wednesday night, the Russian president said his government was considering changing the rules and preconditions around which Russia would use its nuclear arsenal.
Ukraine is a non-nuclear state that receives military support from the US and other nuclear-armed countries.
His comments come as Kyiv seeks approval to use long-range Western missiles against military sites in Russia.
Ukraine’s President Volodymyr Zelensky has travelled to the US this week and is due to meet US President Joe Biden in Washington on Thursday, where Kyiv’s request is expected to be top of the agenda.
