Drone strikes sink cargo ships in NATO waters as EU calls attacks 'unacceptable'

Cargo ships are sinking in NATO waters. On October 6, 2026, a coordinated drone assault — combining aerial and sea-surface drones — struck two commercial vessels roughly 70 to 80 miles off the Bulgarian coast, sinking one ship and setting the other ablaze. The attack occurred inside Bulgaria's exclusive economic zone, making it the first time drone strikes of this kind have sunk ships within the EEZ of a NATO member country.

The Togo-flagged cargo ship Alfa Watan sank after suffering what British maritime risk group Vanguard described as catastrophic structural damage. The fate of its crew was not immediately known. After witnessing an explosion and picking up distress signals, the Bulgarian ferry Dioscuria altered course for the area; rescue teams arriving at the scene discovered an upturned lifeboat along with life rafts and life jackets scattered through the debris. Search-and-rescue operations were launched by Bulgaria's Navy, Air Force, and Border Police.

The second vessel, the Palau-flagged general cargo ship Able, was set ablaze while carrying wheat southbound. All 18 seafarers on board — 11 Turkish nationals and seven Indian nationals — were brought to safety by the Bulgarian ferry crew. Of those, two sustained severe injuries and were airlifted to a hospital in Varna, while the other 16 were brought ashore without incident.

Such an attack within the Bulgarian exclusive economic zone is absolutely unacceptable. If this war is not ended in time, it will continue to expand its spatial scope and increase the risk of even a global conflict.— Rumen Radev, Bulgarian Prime Minister

In the wake of the strikes, Radev called an emergency government session and, according to Reuters, characterized the incidents as "a gross, flagrant violation of international law." Whether the drones had been launched by Russia or Ukraine, he said, had yet to be determined.

Ukrainian President Volodymyr Zelenskyy did not share that ambiguity. A joint investigation conducted with Bulgaria's navy, he said, had confirmed that the attacks amounted to "a Russian combined attack using both sea and aerial drones," and he stated that Ukrainian forces had carried out no operations in that section of the Black Sea. Zelenskyy also warned that Russia was preparing a broader 'massive strike.'

Our intelligence and special services are now working to establish all available information about yet another attack in the Black Sea targeting civilian vessels. Our Navy contacted its counterparts in Bulgaria, and it has been established that this was a combined Russian attack using maritime and aerial drones.— Volodymyr Zelenskyy, Ukrainian President

EU Commission President Ursula von der Leyen called the attacks 'unacceptable' and described the Black Sea situation as 'increasingly concerning,' while cautioning that the exact circumstances were 'still being established' without naming a probable attacker. According to Ars Technica, she posted on X that "We stand in full solidarity with our Member States on the Eastern flank."

The October 6 strikes came one day after drones hit the Turkish-owned cargo ship Royad Mammadov inside Romania's exclusive economic zone on October 5. That ship caught fire and eventually sank; Romanian ships and helicopters rescued 11 crew members, one remains missing, and two were killed, according to Ars Technica. The Royad Mammadov had taken on a cargo of corn at the Ukrainian port of Ismail and, according to reports, was struck by a combination of aerial drones and drone boats.

Drone expert Cameron Chell, founder of drone manufacturer Draganfly, told Fox News Digital that the nature of the Bulgarian strikes pointed to a hybrid attack — likely combining an aerial drone such as the Geran-4 with a surface drone such as the Maran. He explained that aerial drones typically descend at steep angles on final approach, making it difficult for them alone to strike a vessel at the waterline with enough force to cause rapid sinking. A surface drone, by contrast, could deliver a below-waterline impact.

The nature of this strike suggests there was a combination of an air attack and surface attack. Not only are you using pretty sophisticated equipment, but you're also doing it in a coordinated manner. These two ships were going opposite directions. One was actually just coming, and had left Ukraine the day before. These things coordinated and were struck relatively at the same time.— Cameron Chell, founder, Draganfly

Chell described the attacks as 'an expansion of strategy and tactics' and said striking ships inside Bulgaria's EEZ could disrupt a critical shipping corridor and spread fear among commercial operators — drawing a parallel to how Iran has used maritime chaos in the Strait of Hormuz to deter commercial traffic. Regarding Russia, he added: "This is indicative of this larger invasion posture that seems to be unfolding for Russia."

The Black Sea has become an increasingly contested maritime arena since Russia's full-scale invasion of Ukraine in February 2022. Ukraine, lacking a traditional navy, has used aerial and sea-surface drones to challenge Russian naval control, striking Russian warships and ports. Russia has responded with its own drone attacks on Ukrainian ships, ports, and international commercial vessels carrying grain and other cargo. According to Ars Technica, Romanian military divers had earlier recovered and destroyed two Russian-made drones discovered near the Neptun Deep offshore gas platform in August, after which Romania dispatched fighter jets to neutralize a Russian drone boat packed with explosives found close to the same installation.

The attacks on ships inside NATO members' exclusive economic zones represent a threshold not previously crossed in the conflict, and European officials have been tracking a broader pattern of incidents attributed to Russian hybrid warfare across the continent. Moscow has not commented on the October 6 strikes.

Why it matters — For the first time, drone strikes have sunk commercial ships inside the exclusive economic zones of NATO member states, raising the risk of direct alliance entanglement and threatening the Black Sea shipping lanes that carry grain and other cargo critical to global food supply.
