Ukraine’s continued focus on Kursk shows how important Kyiv believes it is to hold on to Russian land, especially if Trump pushes both sides to the negotiating table.

Ukraine is leaning into its efforts to hold onto the Russian territory of Kursk amid intense pressure from Russian and North Korean forces to take it back, apparently gambling that the region could be a valuable card in potential negotiations with Moscow.

Russia said on Monday its forces had made important gains in eastern Ukraine while continuing to fend off a new Ukrainian offensive inside the Kursk region of western Russia, where a second day of fierce fighting was under way.
