Ukraine reportedly carried out attacks on maritime targets in the Caspian Sea over the weekend, although details of the operation remain unconfirmed. According to reports, Iran raised formal complaints with both the United Nations and the European Union, describing the incident as a serious escalation. Ukrainian President Volodymyr Zelensky stated that vessels allegedly involved in transporting military cargo between Iran and Russia, along with a military vessel, were among the targets.

Media reports said an Iranian cargo ship was struck on its bridge, resulting in the death of one sailor and significant damage to the vessel. The ship reportedly required assistance from maritime authorities in Astrakhan after the attack. Other reports suggested that the Russian cargo vessels Port Olya 2 and Begey, both previously sanctioned by Western governments, may also have been targeted, although official confirmation has not been provided.

The Caspian Sea has become an important shipping corridor linking Iranian ports, including Bandar Anzali and Amirabad, with southern Russia through the Volga-Don Canal system. Analysts have previously reported that the route has been used to transport military-related cargo, including ammunition and drones, between Iran and Russia. Maritime observers note that the corridor has grown in strategic importance as alternative transport routes have faced increasing restrictions.

Ukraine has expanded its long-range operations against Russian maritime logistics since 2024, including previous attacks on naval assets in the Caspian region. Recent reports indicate that the campaign has increasingly focused on disrupting supply routes connected to Russia\'s military operations. As of now, authorities from the countries involved have not released comprehensive official details on the reported attacks or the full extent of the damage.
