Russian forces have recaptured Sudzha, the largest town that Ukraine once occupied in the Kursk region, according to Moscow, threatening Kyiv’s sole territorial bargaining chip amid pressure to negotiate an end to the war.

Ukrainian officials have not confirmed a retreat from the town in Russia’s Kursk region, parts of which were captured by Kyiv’s forces last summer.

Russian President Vladimir Putin visited the region for the first time since Kyiv’s lightning incursion and as peace talks gain steam.
