Drone strike sinks Turkish cargo ship in Black Sea, crew unaccounted

BRUSSELS — Two Turkish‑owned cargo ships were struck by unmanned aerial systems in the Black Sea off the Bulgarian coast on Oct. 5, 2026, one of the vessels sank and its crew of 22 remains missing, Bulgarian authorities said.

According to the Bulgarian Ministry of Transport, the attacks occurred near the port city of Burgas around 02:30 GMT. The first drone hit the bulk carrier MV Kardelen, causing a fire that was extinguished without loss of life. Minutes later a second unmanned vehicle struck the sister ship MV Yavuz, breaching the hull and sinking the vessel within an hour.

Emergency response and search operations

Bulgarian emergency services launched a coordinated rescue effort involving the navy, coast guard, and civilian vessels. An emergency meeting of the national security council was convened in Sofia, where officials reviewed aerial surveillance footage and deployed additional search‑and‑rescue helicopters.

The Bulgarian coast guard reported that divers recovered debris and personal effects from the wreckage, but no survivors. The missing crew, all Turkish nationals, were last seen on deck as the ship listed heavily before disappearing beneath the surface.

Turkish ownership and official statements

Turkey’s Ministry of Transport confirmed that both ships were registered under Turkish flags and owned by the Istanbul‑based shipping firm Denizline Logistics. In a brief statement, the ministry said it was monitoring the situation closely and had dispatched a liaison team to Sofia to assist Bulgarian authorities.

Denizline Logistics issued a press release acknowledging the loss of MV Yavuz and expressing concern for the crew’s families. The company said it would cooperate fully with the investigation and provide any required documentation to the Bulgarian and Turkish maritime agencies.

Regional context and security implications

The Black Sea has seen a rise in unmanned aerial system activity since the escalation of hostilities between Russia and Ukraine in early 2022. While neither Moscow nor Kyiv claimed responsibility for the Oct. 5 attacks, security analysts note that the use of drones to target commercial shipping reflects a broader trend of asymmetric warfare in the region.

European Union maritime security officials have warned that the proliferation of commercially available drones poses a growing threat to civilian vessels operating in contested waters. The EU’s Maritime Security Strategy, updated in 2025, calls for enhanced surveillance and rapid‑response capabilities along the Black Sea littoral states.

Investigation underway

Bulgarian prosecutors opened a criminal investigation under the Penal Code provisions for sabotage and endangering public safety. The investigation will examine the origin of the drones, the command structure behind the operation, and any possible links to state or non‑state actors.

Forensic analysis of the recovered wreckage is being conducted by the National Institute for Maritime Research in Varna. Preliminary findings indicate that the drones were equipped with high‑explosive payloads capable of breaching steel hulls.

Impact on shipping routes

The incident prompted the Bulgarian Maritime Authority to issue a temporary advisory urging vessels to avoid the immediate area and to increase vigilance for aerial threats. Shipping companies operating in the Black Sea have reported minor schedule adjustments but no widespread cancellations.

Insurance firms noted a modest uptick in premiums for Black Sea cargo coverage following the attack, citing heightened risk assessments. However, the overall volume of trade through the Black Sea corridor remained stable, according to data from the International Chamber of Shipping.

International reaction

The United Nations Office on Drugs and Crime (UNODC) reiterated its call for all parties to respect the safety of civilian maritime traffic under international law. No nation has formally claimed responsibility for the drone strikes.

As the search for the missing crew continues, Bulgarian authorities have appealed for information from any vessels that may have observed the drones or the sinking. The next update from the Bulgarian Ministry of Transport is scheduled for Oct. 8.
