The U.K. government on Thursday warned the Kremlin against officially recognizing Ukraine's two "L/DPR" territories, days after the Russian parliament voted to call on President Vladimir Putin to do so.

"The Duma's request for Vladimir Putin to recognize the Donetsk and Lugansk regions of Ukraine as independent shows a blatant disregard for Russia's commitments under the Minsk agreements," British Foreign Secretary Liz Truss said in a statement.

"If this request were accepted, it would be a further attack on Ukraine's sovereignty and territorial integrity, signaling the end of the Minsk process and demonstrating Russia's decision to choose the path of confrontation rather than dialogue," Truss said.

"We call on Russia to end its pattern of destabilizing behavior toward Ukraine and fulfill its voluntary commitments, including the Minsk agreements."

On Tuesday, the Russian parliament Duma voted to call on Putin to "recognize the independence" of two Ukrainian regions amid tensions with the West over Moscow's troop buildup nearby.

Russia has issued passports to hundreds of thousands of residents of the "L/DPR."

Duma's proposal drew sharp condemnation from the United States, with Secretary of State Anthony Blinken saying it would be a gross violation of international law.
