Bulgaria Halts Search for Missing Sailors After Drone Attack Sinks Cargo Vessel in Black Sea

Bulgarian maritime authorities have called off the search for crew members missing after a drone strike sank a commercial cargo ship in the Black Sea, confirming that no survivors were located during the rescue operation. The decision to end the search late Tuesday came roughly a day after the vessel went down, leaving an unknown number of sailors unaccounted for in the waters off Bulgaria's eastern coast.

Rumen Nikolov, who heads Bulgaria's Maritime Search and Rescue Coordination Centre, told reporters on Wednesday that rescue teams had found no sign of the missing crew. "There is no trace of the sailors," he said, adding that the operation had been suspended and would not resume. The grim announcement followed an intensive search effort that also involved the rescue of eighteen crew members from a second vessel damaged in the same attack.

The incident unfolded early Tuesday when drones targeted two commercial ships in the Black Sea region, one of which caught fire while the other sank. The eighteen rescued crew members—described as Turkish and Indian nationals—were aboard the vessel that caught fire. They were brought ashore by Bulgarian border police, according to images from the scene in the coastal city of Varna.

Authorities have not publicly confirmed how many people were aboard the ship that sank. However, the specialised maritime news website Maritime.bg reported that ten people had been on board the vessel at the time of the attack. That figure, if accurate, would mean ten sailors remain missing and are now presumed lost.

Nikolov offered a detailed account of what search teams recovered from the water, describing "one overturned boat, three life rafts and debris from the ship's equipment that was floating on the surface of the sea." He said no drone debris had been recovered, telling reporters he had "no information" on that front. The absence of such evidence leaves open questions about the weapons used and their point of origin.

The strikes occurred about 80 nautical miles (roughly 150 kilometres) east of Byala, a Bulgarian coastal town. Nikolov noted that the attack took place in what is designated a "responsible search and rescue zone" rather than within Bulgaria's territorial waters, which extend 12 nautical miles from the coast. The distinction matters for jurisdiction and for how the response was coordinated.

Timing details released by authorities shed light on how the emergency unfolded. A distress beacon from the sunken vessel was received at 2:54am local time on Tuesday, corresponding to 23:54 GMT on Monday. The distress signal from the second ship arrived about half an hour later, at 3:23am local time (00:23 GMT). Both vessels were managed by companies based in Turkiye, according to the Equasis merchant shipping database.

The attack prompted swift condemnation from senior Bulgarian and European officials. Prime Minister Rumen Radev called the strike "absolutely unacceptable." European Commission President Ursula von der Leyen also denounced the incident. Despite the strong political reactions, Bulgarian authorities said they were not yet able to establish where the drones had come from, leaving the question of responsibility unresolved.

The Black Sea strikes are part of a broader pattern of escalating attacks on shipping in the region as the Russia-Ukraine war intensifies. The drone assault on the two vessels came just one day after a separate ship caught fire and sank off the coast of Romania on Monday, killing two people. Ukraine blamed Russia for that attack, according to statements reported at the time.

The cumulative effect of these incidents is a growing sense of insecurity for commercial shipping in the Black Sea, a waterway that borders NATO members Bulgaria, Romania and Turkiye as well as Ukraine and Russia. The targeting of merchant vessels raises concerns not only for crew safety but also for regional trade routes and the insurance costs that accompany heightened risk.

For Bulgaria, the episode has highlighted the challenges of responding to attacks that occur outside its territorial waters but within a search and rescue zone it oversees. The country's maritime coordination centre mounted a rapid response, yet the outcome—eighteen saved, an unknown number lost—underscores the lethal dangers facing civilian mariners in the conflict's periphery.

The lack of clarity over the drones' origin is likely to fuel further diplomatic tensions. Bulgaria, a European Union and NATO member, has been cautious about attributing the attack while investigations continue. The recovery of debris from the drones could prove pivotal in establishing accountability, but Nikolov's statement that no such debris had been found suggests that determination may take time.

International bodies have repeatedly warned that the spillover of the war into civilian shipping lanes carries serious consequences. The Black Sea has already seen disruptions to grain exports and other trade since the conflict began, and each new attack on commercial vessels compounds the risks for shipping companies and their crews.

The families of the missing sailors now face the difficult reality that the search has ended without answers. With rescue operations halted and no trace of the crew found, the focus shifts to identifying the victims and determining the circumstances of the sinking. The overturned boat and scattered life rafts recovered from the sea stand as the only physical evidence of the vessel's final moments.

As the war continues, the attack off Bulgaria's coast serves as a stark reminder of how far the conflict's effects reach beyond the front lines. The eighteen rescued crew members are safe, but the missing sailors from the sunken ship remain lost at sea, their fate sealed in an attack that authorities have condemned but cannot yet fully explain.
