Russian forces allegedly targeted a nursing home facility in the Ukrainian-controlled territory of the Kursk region.

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.

The surprise attack seeks to reverse Ukraine’s decreasing hold of the region. Since Kyiv’s forces gained partial control of Kursk following a daring cross-border assault last August, Russian troops, aided by North Korean soldiers, have halved the territory held by Ukraine, albeit while suffering thousands of casualties.

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.

Russian forces continue to make costly but consistent gains in the Donetsk region in eastern Ukraine. They are steadily grinding down a pocket of resistance around the town of Kurakhove and are also fighting to envelop the larger nearby city of Pokrovsk, Ukrainian soldiers and officials said.

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.
