Eleven sailors missing after drone sinks ship off Bulgaria

Two cargo ships were struck by drones overnight near Bulgaria. The HS Dignity, flying the Guinea-Bissau flag, sank off Krapets. Five crew members were rescued, but 11 remained missing as the search continued. The sinking may have been the second deadly cargo-ship loss in the area within a week.

The Maltese-flagged Chelsea 3 was also hit by three drones. Its entire crew survived: seven Ukrainians and eight Azerbaijanis. None was seriously injured. These incidents show how attacks can affect both vessels that sink and ships that remain afloat.

The missing sailors made the attack a major humanitarian and security incident for Bulgaria. Officials summoned Russia’s ambassador, while Bulgaria requested stronger maritime and airspace surveillance. Moscow did not immediately comment, and the ambassador said she had no information about attacks on commercial vessels.

A drone attack is an assault carried out by an aircraft that is operated remotely or flies without a person aboard. Drones can carry explosives, collide with a target, or deliver weapons. The source reports drone strikes but does not identify the drones or their exact payloads.

A large cargo ship is difficult to sink, but its size does not make it invulnerable. A strike can tear open the hull, damage steering or propulsion, ignite fuel or cargo, or disable pumps and communications. Water entering damaged compartments can reduce stability. Several hits may multiply the damage and prevent the crew from controlling flooding or fire.

The reported attacks show the wider danger. Three drones hit Chelsea 3, while another strike sank HS Dignity. The article does not establish exactly how the sinking occurred. It does show that unmanned attacks can endanger civilian crews and disrupt commercial routes.

The latest attacks involved two ships: HS Dignity and Chelsea 3. HS Dignity had 16 crew members, with five rescued and 11 missing. Chelsea 3 carried 15 crew members, including seven Ukrainians and eight Azerbaijanis; all were rescued. Together, the latest incidents involved 31 sailors.

A week earlier, two more ships were hit in Bulgaria’s Black Sea exclusive economic zone. One sank, leaving nine Syrian sailors and one Egyptian lost at sea. Another ship was hit, but its crew was rescued. The article does not give that second crew’s size, so the full sailor total cannot be calculated.

Thus, four ships were involved in the reported attacks, and at least 41 sailors are specifically counted. The known human toll includes 11 currently missing, 10 lost earlier, and 20 rescued in the latest incidents. The search for the missing crew remained underway.

The location matters because Bulgaria is a coastal state and a NATO member. Prime Minister Rumen Radev called the latest incident another attack in the immediate vicinity of Bulgarian territorial waters. An attack so close to national waters can threaten civilian safety, test surveillance systems, and create pressure for a government response.

The earlier sinking happened inside Bulgaria’s Black Sea exclusive economic zone. That wider maritime area supports commercial activity and gives Bulgaria important legal and economic interests, even though it is not the same as territorial waters. The attacks therefore affected shipping in waters closely connected to Bulgaria’s security.

Bulgaria summoned Russia’s ambassador and asked NATO for help strengthening maritime and airspace surveillance. The European Union, Ukraine, and NATO condemned or addressed the danger. Repeated incidents could increase military deployments, insurance concerns, and route disruptions, while making the Black Sea an even more active front in the war.

Repeated attacks threaten the Black Sea’s role as a commercial corridor. Ships may face greater danger, delays, insurance costs, and pressure to avoid exposed routes. Ports and crews could also require stronger protection. These effects would deepen what the article calls a prolonged battle of economic endurance.

The stakes extend beyond the ships themselves. Russia and Ukraine are both among the world’s largest grain exporters. Russia has bombed Ukrainian Black Sea ports, while Ukraine has increasingly targeted Russian grain-exporting ships elsewhere in the Black Sea and in the Azov Sea. Such attacks can disrupt loading, sailing, and access to markets.

Ukraine’s foreign minister described the Black Sea as a lifeline for global food security and accused Russia of trying to weaponise hunger. The article does not quantify any grain shortage. It does show a risk: continuing attacks could shift more trade to longer or more protected routes and increase pressure on governments to secure shipping.

Russia’s full-scale invasion changed both port access and sailing patterns. According to the article, Russia has bombed Ukraine’s Black Sea ports. That pressure made it harder for Ukraine to depend on its traditional maritime gateways and forced it to seek safer alternatives.

Ukraine increasingly relied on river ports on the Danube. It also used shipping routes close to the coasts of NATO members Bulgaria and Romania. These routes place civilian vessels near countries whose waters and surveillance systems are closely tied to the conflict’s regional security environment.

The change has not removed the danger. Ukraine has increasingly targeted Russian grain-exporting ships in other parts of the Black Sea and in the Azov Sea near the Don River’s mouth. The result is a broader struggle around trade access, grain exports, and economic pressure, with commercial shipping increasingly drawn into the war.

Under widely accepted international maritime law, territorial waters extend up to 12 nautical miles from a coast. The coastal state has sovereignty there, subject to rules such as innocent passage for foreign ships. An exclusive economic zone, or EEZ, can extend up to 200 nautical miles. It gives the coastal state rights over resources and certain jurisdiction, but not complete sovereignty over every activity.

Commercial ships may generally navigate both areas while following applicable law. Military activity is more complicated. International law does not automatically ban foreign military operations in an EEZ, and states disagree about some activities. In territorial waters, a foreign warship’s passage must meet the rules for innocent passage.

The article identifies attacks near Bulgarian territorial waters and an earlier sinking in Bulgaria’s EEZ. It does not provide exact coordinates or a legal ruling. Bulgaria’s summons, surveillance request, and diplomatic response show why location matters, but responsibility and legality remained disputed.
