A Russia-appointed official in Ukraine’s occupied Luhansk region said Monday that Moscow’s forces have overrun all of it — one of four regions Russia illegally annexed from Ukraine in September 2022 despite not fully controlling a single one, Associated Press reported.

If confirmed, that would make Luhansk the first Ukrainian region fully occupied by Russia after more than three years of war and as recent U.S.-led international peace efforts have failed to make progress on halting the fighting. 

Russian President Vladimir Putin has effectively rejected a ceasefire and hasn’t budged from hisdemands, which include Moscow’s control over the four illegally annexed regions. 

There was no immediate comment from Kyiv on the claim made by the Moscow-installed leader of the occupied region, Leonid Pasechnik. In remarks to Russia’s state TV Channel One that aired Monday evening, Pasechnik said he received a report “literally two days ago” saying that “100%” of the region was now under the control of Russian forces, according to Associated Press.
