President Vladimir Putin said on Thursday that Russia had trapped the remaining Ukrainian soldiers in its western Kursk region, where they have clung on for more than seven months in one of the key battles of the war.

Russia claimed Thursday that its troops have driven the Ukrainian army out of the biggest town in Russia's Kursk border region, as a senior Kremlin official said that a U.S.-proposed 30-day ceasefire in the three-year war on Ukraine would help Kyiv by giving its military a break.
