The United States will take steps in response to Russia's recognition of the so-called "Donetsk People's Republic" and "Luhansk People's Republic" in coordination with partners, U.S. Secretary of State Antony Blinken has said.

"Kremlin's recognition of the so-called 'Donetsk and Luhansk People's Republics' as 'independent' requires a swift and firm response, and we will take appropriate steps in coordination with partners," Blinken said on Twiiter on Monday, February 21.
