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.

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

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.

The 67th Separate Mechanized Brigade repelled an assault of Russian troops near the village of Zhuravka in Sumy Oblast on the border with Russia's Kursk Oblast, according to the brigade's Jan. 15 statement.

Russia's Defense Ministry said its forces had retaken 63.2% of Ukrainian-held territory in the Kursk region of western Russia. Meanwhile, Germany's top diplomat has criticised the Berlin row over aid.
