Kremlin warns that use of US missiles would be a 'radical change' in war

The Kremlin has said that US President Joe Biden's move to allow Ukraine to use US-supplied missiles to strike inside Russia would be a "radical change in the essence and nature of the conflict.”

In a statement from Russia's Foreign Ministry, the Kremlin added that a move by Ukraine to use the missiles to strike Russian territory would mean "the direct involvement of the United States and its satellites in military action against Russia." 

Although Russian President Vladimir Putin has yet to comment on Biden's decision, his press secretary Dmitry Peskov confirmed that the move made it obvious that Washington is "adding fuel to the fire and provoking further tensions" around the war between Russia and Ukraine.
