Drones hit two ships off Bulgaria, sinking one and raising new risk for Black Sea trade
Two ships were struck by drones about 24 km off Bulgaria’s Black Sea coast on 13 October, with one sinking and another damaged, according to Prime Minister Rumen Radev. Bulgaria has summoned Russia’s ambassador as investigators work to identify the vessels, their cargo and who launched the drones.
Drones striking commercial ships within sight of Bulgaria’s coastline have turned a routine stretch of the Black Sea into a security problem with global trade implications.
On 13 October, two ships were hit by drones about 24 kilometers off Bulgaria’s coast, Rumen Radev, the country’s prime minister, said. One vessel sank and another was damaged.
Radev said the origins of the ships and their cargo, as well as the source of the drones, were still unknown. His early statement placed the incident roughly off Bulgaria’s northern shoreline.
In a separate move reported publicly, Sofia summoned Russia’s ambassador. That step signals that Bulgarian authorities want answers from Moscow, but there has been no public attribution of responsibility and no state has claimed the attack.
Key facts remain unclear. Officials have not named the flag states of the ships. The type of drones used, where they were launched from, and whether they were aimed at specific targets have not been disclosed. No government has confirmed what the ships were carrying.
That uncertainty leaves ship crews, port authorities and insurers trying to gauge risk from partial information. A single drone strike can puncture a hull, ignite fires or knock out navigation, putting sailors in the water or leaving a vessel adrift with little warning.
The area where the ships were struck serves cargo moving in and out of Black Sea ports, including grain, oil and container traffic. If owners conclude that parts of this route are too dangerous, they can divert ships to longer and more expensive river and land corridors through neighboring states.
The incident also shifts attention to how close attacks are coming to European Union coastlines. Until now, concern over drone and missile strikes on shipping in this war has mainly focused farther east, near Ukrainian ports and contested waters.
A few more incidents of this kind would likely trigger visible steps: more patrols and surveillance in the area, changes in insurance terms for ships near Bulgaria’s coast, and, if investigators can identify the drones or their launch point, sharper diplomatic and military planning based on that evidence.
