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.

Ukraine launches a new offensive in Russia's Kursk region, raising questions about its strategic goals and potential impact on the war's trajectory and upcoming peace talks.

Ukraine launched a fresh operation in Russia's southern Kursk region, Moscow said on Sunday, after Ukrainian officials and military bloggers reported new attacks from Kyiv in a region where Moscow is eager to reassert its grip.

Ukraine has largely been driven out of Kurakhove, a battered but strategic town in the Donbas, Russia said. Kyiv’s forces were pressing a renewed offensive in southern Russia.

Russian military commentators say they are ‘worried’ about the multipronged Ukrainian attack in the border region of Kursk

Ukraine strikes 3 Russian air defense systems in single day, Navy claims 3,800 North Korean troops killed or injured in Russia's Kursk Oblast, Zelensky says Ukraine's position in Kursk Oblast important for possible negotiations,

Ukraine's fresh offensive in Kursk comes nearly six months after Kyiv first sent troops into the western Russian region.

Ukraine's president told podcaster Lex Fridman that 3,800 North Koreans had been killed or wounded fighting alongside Russia but many more could come.

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,
