A Russian missile attack on a supermarket in Kostiantynivka, eastern Ukraine, has killed at least 14 people and injured 43, according to Ukrainian officials. This incident follows Ukraine's incursion into Russia's Kursk region, where Ukrainian forces have occupied significant territory and destroyed Russian military assets, including a convoy and helicopters. Russia has declared a federal emergency in Kursk and is sending reinforcements to counter the Ukrainian offensive. The ongoing conflict has resulted in increased civilian casualties and further strained international relations. Ukrainian President Zelenskyy vowed that Russia will be held accountable for its actions, as emergency services continue to search for survivors in Kostiantynivka.
