Bulgarian authorities believe Russia is the most likely party behind recent drone attacks on commercial vessels in the Black Sea, while acknowledging that there is currently no direct evidence proving Russian involvement.
Over the past week, drones have attacked four vessels in Bulgaria’s exclusive economic zone and nearby waters. Two of the ships sank. Following the latest attacks, rescuers continued searching for 11 missing crew members.
Bulgarian officials said the circumstances surrounding the attacks point to possible Russian involvement but stressed that conclusive evidence has not yet been established.
Sofia has requested international assistance and NATO support to strengthen surveillance and protect shipping in the Black Sea. Russia has not acknowledged involvement in the attacks.
