Ukraine claimed Saturday to have struck one of Russia’s largest oil refineries in a drone attack, starting a fire at the facility more than 700 miles into Russian territory.

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.

Ukraine launched a daring offensive into Russia's Kursk region, hoping to stretch Russia's resources and gain a new bargaining chip.

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.
