Ukraine achieved a significant naval victory by attacking a Russian warship in Crimea, but suffered a setback in the city of Marinka. The war has reached a stalemate, with Ukraine targeting Russian assets in Crimea and Russia pressing its attack in eastern battlefields. Ukraine's military acknowledged retreating from Marinka, emphasizing the high cost of staying and fighting. The attack on the Russian warship follows the downing of five Russian fighter jets, indicating Ukraine's increased pace of strikes on the peninsula. The capture of Marinka could allow Russian forces to advance further, while Ukraine is preparing a defensive line outside the city. This escalation comes as Ukraine signals readiness for a protracted war against Russia.
