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.

Ukrainian President Volodymyr Zelenskiy said on Monday that Russia had suffered heavy losses in five months of fighting Ukrainian forces in southern Russia's Kursk region, with nearly 15,000 killed.

Ukraine appeared to launch a fresh offensive Sunday in Russia’s border region of Kursk, where Kyiv’s forces have held territory for several months.

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.

A total of 144 combat clashes have occurred on the battlefield since the start of 9 January, with most of the fighting taking place on the Pokrovsk, Kursk and Kurakhove fronts. Source: General Staff of the Armed Forces of Ukraine on Facebook,
