Ukraine President Volodymyr Zelensky acknowledged for the first time on Saturday that Ukrainian forces were fighting in the surprise offensive in Russia's Kursk, as attacks on the border region continued with authorities rushing to evacuate people.

Moscow's forces were in their sixth day of intense battles against Kyiv's largest incursion into Russian territory since the start of the war, which left southwestern parts of Russia vulnerable before reinforcement started arriving.

In a sign of the gravity of the situation, Russia imposed a sweeping security regime in three border regions on Saturday, while Belarus, a staunch ally of Moscow, sent more troops to its border with Ukraine, accusing Kyiv of violating its air space.
