The Russian army continues its offensive in the Kursk region. According to the latest updates, the buffer zone controlled by Ukraine's Defense Forces has once again shrunk, the General Staff of the Ukrainian Armed Forces reports.

At the height of the campaign, Ukrainian forces controlled some 500 square miles of Russian territory. Now they hold just a small sliver of land along the border.

President Zelenskiy said his troops in Kursk were not surrounded, but said there might be a new Russian attack on Ukraine's northeastern Sumy region.
