Kyiv renewed its offensive in Russia’s Kursk region, as Ukraine tries to hold territory there ahead of US President-elect Donald Trump’s inauguration. Since Ukraine’s initial incursion into Kursk in August — the first invasion of Russia since World War II — Moscow has regained much of its lost territory.

Russia said Sunday that Ukraine had launched a "counterattack" in the western border region of Kursk, where Kyiv's forces began a shock ground offensive last August. Both Russia and Ukraine have exchanged regular attacks since the year began.
