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

Bulgarian maritime authorities have called off the search for crew members missing after a drone strike sank a commercial cargo vessel in the Black Sea, confirming that no survivors were located in the operation. The decision to end the rescue effort came late on Tuesday, with officials acknowledging that the missing sailors could not be found despite an extensive search of the area.

Rumen Nikolov, who leads Bulgaria's Maritime Search and Rescue Coordination Centre, told reporters on Wednesday that there was no sign of the missing crew. "There is no trace of the sailors," he said, adding that the search had been formally suspended and would not resume. The confirmation brought a somber close to a rescue operation that had been launched immediately after the attack early Tuesday morning.

The incident involved two commercial vessels that were struck by drones in quick succession. One of the ships caught fire, while the other sank beneath the waves. Eighteen crew members — a mix of Turkish and Indian nationals — were pulled to safety from the vessel that caught fire. However, those aboard the ship that went down remain unaccounted for.

Authorities have not released an official figure for the number of missing sailors. According to the specialized maritime news website Maritime.bg, approximately ten people were on board the vessel that sank. The discrepancy between the rescued and the missing highlights the severity of the attack, which left one ship destroyed and its crew lost at sea.

Nikolov provided details about the location of the strike, noting that it occurred in what is described as a "responsible search and rescue zone" rather than within Bulgaria's territorial waters. Bulgarian territorial waters extend twelve nautical miles from the coast, placing the attack site outside the country's direct jurisdiction but still within an area where Bulgaria bears rescue responsibility.

The coordinates of the attack placed the two ships roughly eighty nautical miles, or about 150 kilometers, east of Byala, a coastal town in Bulgaria. The distance from shore complicated rescue efforts and underscored the vulnerability of shipping lanes in the contested Black Sea region. Debris recovered from the sunken vessel included an overturned boat, three life rafts, and fragments of the ship's equipment floating on the surface, according to Nikolov. He added that he had no information regarding any recovered drone debris, leaving questions about the attack's origin unanswered.

The timeline of the attacks was reconstructed through distress signals. The beacon from the ship that sank was received at 2:54 a.m. local time on Tuesday, which corresponded to 11:54 p.m. GMT on Monday. A second distress signal, from the vessel that caught fire, arrived at 3:23 a.m. local time, or 12:23 a.m. GMT. The near-simultaneous distress calls pointed to a coordinated strike rather than an isolated incident.

Both commercial ships were managed by companies based in Turkiye, according to records from Equasis, a merchant shipping database. The involvement of Turkish-operated vessels adds a diplomatic dimension to the incident, as Ankara has maintained delicate relations with both Kyiv and Moscow throughout the ongoing war. The nationalities of the rescued crew — Turkish and Indian — further internationalize the consequences of the attack.

Bulgarian Prime Minister Rumen Radev condemned the strike in strong terms, calling it "absolutely unacceptable." His statement reflected the gravity with which Sofia views attacks on commercial shipping in its vicinity. European Union chief Ursula von der Leyen also denounced the incident, signaling that the bloc regards the strike as a serious escalation. Despite the condemnations, Bulgarian authorities have stated they are not yet able to determine the origin of the drones responsible for the attack.

The attack fits a broader pattern of escalating violence against shipping in the Black Sea as the Russia-Ukraine war intensifies. Just one day before the Bulgarian incident, another ship caught fire and sank off the coast of Romania on Monday, resulting in two deaths. Ukraine blamed Russia for that drone attack, though Moscow has not publicly responded to the allegation. The proximity of the two incidents — one off Romania and one off Bulgaria — suggests a widening theater of maritime aggression.

The strikes have raised concerns about the safety of commercial navigation in the Black Sea, a vital corridor for grain, energy, and other commodities. Since the collapse of previous agreements meant to protect shipping, vessels have increasingly come under threat. The use of drones — relatively cheap, hard to attribute, and capable of precise strikes — has introduced a new and unpredictable danger for crews operating in the region.

For Bulgaria, a NATO member and EU state, the attack presents a delicate balancing act. While Sofia has condemned the strike, it has stopped short of assigning blame, likely reflecting a desire to avoid direct entanglement in the conflict. The decision to end the search without recovering the missing sailors leaves unanswered questions for their families and for the shipping companies involved.

The international response has so far been limited to statements of condemnation. It remains unclear whether the incident will prompt any coordinated action by NATO, the European Union, or individual states to enhance maritime security in the Black Sea. For now, the families of the missing crew members face the painful reality that their loved ones may never be found, as the search operation has officially concluded with no trace of the sailors.
