The announcement was issued as Ukrainian President Volodymyr Zelenskiy held talks in Paris and ahead of U.S. envoy Steve Witkoff’s meetings in Moscow on a U.S.-backed plan to reach a settlement of the more than 3-1/2-year-old war.

Valery Gerasimov, chief of the Russian military’s General Staff, reported to Putin during the president’s visit on Sunday to an unidentified military command post that Russian troops had captured Pokrovsk, known in Russian as Krasnoarmeysk.
