Ukrainian troops piled pressure on retreating Russian forces Tuesday, pressing a counteroffensive that has produced major gains and a stunning blow to Moscow's military prestige.
As the advance continued, Ukraine’s border guard services said the army took control of Vovchansk — a town just 3 kilometers (2 miles) from Russia seized on the first day of the war. Russia acknowledged that it has withdrawn troops from areas in the northeastern region of Kharkiv in recent days.
