In a major escalation of the conflict, Ukrainian forces launched a surprise cross-border offensive into Russia's Kursk region, marking one of Kyiv's most significant attacks on Russian soil since the war began. Ukrainian troops advanced rapidly, causing significant damage and forcing thousands of Russian residents to evacuate. The Kremlin declared a 'federal-level' emergency and sent reinforcements to counter the incursion. Meanwhile, Russia struck a Ukrainian shopping mall in Kostiantynivka, killing at least 11 people and wounding 44 others. Ukrainian President Volodymyr Zelensky suggested the incursion was a response to Russia's aggression, aiming to make Moscow 'feel what it has done' to Ukraine. Despite the intense fighting, the strategic objectives and full extent of Ukraine's territorial gains remain unclear.
