Ukraine shocked the world with its bold offensive operation in the summer that at its height took control of an area about the size of Los Angeles in Kursk, Russia.

Ukrainian troops are still fending off Russian and North Korean forces in the Kursk region but face a potential new attack on Ukraine's northeast Sumy region, President Volodymyr Zelenskiy said on Saturday.

President Volodymyr Zelensky said that Ukrainian troops have not been encircled by Russian forces in Kursk region, accusing Russian leader Vladimir Putin of “lying” about the situation on the ground.

President Volodymyr Zelenskyy of Ukraine gave no indication Friday that his country’s soldiers would withdraw from Kursk, let alone surrender.
