Russia said on Sunday that Ukraine had launched a counter-attack in the Russian region of Kursk, where Kiev forces have already controlled several hundred square kilometers since the assault began in August 2024.

In August, Ukraine launched an unexpected offensive into Russia's Kursk region, targeting poorly defended border areas. Ukrainian brigades used light armored vehicles and local numerical superiority to occupy roughly 1,000 square kilometers of sparsely populated territory, including the small town of Sudzha.
