Amendments to Russia's nuclear doctrine have been prepared and "will now be formalised", the Kremlin said Sunday, days after President Vladimir Putin warned that Russia could use nuclear weapons if it was struck with conventional missiles and would consider any attack backed by a nuclear power to be an attack by that nuclear power.
The Kremlin said on Sunday that amendments to Russia's nuclear doctrine had been prepared and were about to be formalised, meaning the relevant documents setting out the circumstances in which nuclear arms can be used by Moscow will be updated.
