A senior Kremlin official said that a 30-day ceasefire proposed by the U.S. and accepted by Ukraine would help Kyiv.

Russia predicted on Thursday it would swiftly recapture the rest of its western Kursk region from Ukrainian troops who grabbed a foothold there last August and have clung on for more than seven months in one of the key battles of the war.

Russian forces have driven the Ukrainian army out of the biggest town in Russia's Kursk border region, officials claimed Thursday, as U.S. officials sought the Kremlin's response to a proposed 30-day ceasefire in the three-year war that Ukraine has endorsed.
