Fourteen crew members were rescued, while two remain missing.

The vessel was en route to Syria as part of a convoy of Russian naval units tasked with transporting equipment and personnel back to Russia amidst the ongoing withdrawal of Russian forces from the Middle Eastern country.

The exact circumstances leading to the sinking remain unclear, but reports suggest an explosion in the engine room immobilized the ship, which then began taking on water.

Multiple Spanish SAR (Search and Rescue) units and at least one military vessel, the patrol vessel Serviola (P71), were dispatched to the scene to provide assistance.

Additionally, a Diamond D.62 aircraft (registration 9H-DGN, callsign OPSREY2) operating on behalf of Frontex flew over the site of the wreckage.

A Russian Navy vessel from the same convoy heading to Tartus requested to take over the rescue operation, citing the UNCLOS (United Nations Convention on the Law of the Sea) framework. Control of the rescue efforts was subsequently transferred to the Russian military ship.

While the cause of the explosion is still unknown, speculation has inevitably turned to Ukrainian intelligence services, who were the first to report the difficulties faced by the Russian vessel via Twitter.
