The Ukrainian army’s seven-month foothold in the region has been under intense pressure for months from a renewed effort by Russian forces.

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 war three years after the full-scale invasion of Ukraine would help Kyiv by giving its weary and short-handed military a break.

President Vladimir Putin made a surprise visit to Russia’s occupied Kursk region on Wednesday, as the Kremlin considers a US proposal for a 30-day ceasefire with his troops closing in on Ukraine’s only territorial bargaining chip.
