On Sunday, the New York Times reported, citing unnamed American officials, that outgoing US President Joe Biden had removed the restrictions on use of the weapons.

Ukraine’s Vladimir Zelensky claimed that several other Western countries had followed suit, and given Kiev permission to use their long-range missiles against internationally recognized Russian territory.On Monday, US Deputy National Security Adviser Jonathan Finer evaded questions from reporters about Biden’s authorization, saying he was not “confirming any decisions that have or have not been made about US assistance” when it comes to operational issues.Russian President Vladimir Putin has warned that such a step would change the nature of the Ukraine conflict, making NATO a direct participant. The head of state has also updated Russia’s nuclear doctrine to allow a strategic response to a conventional attack by the proxy of a nuclear power. Source
