Bulgaria Summons Russian Ambassador After Drone Attack Sinks Ship, Leaving 11 Missing

Two cargo ships were hit by drones overnight near Bulgaria. The Guinea-Bissau-flagged HS Dignity sank near Krapets. Five crew members were rescued, while 11 others remained missing as search teams continued working. The sinking made the incident a major maritime emergency close to Bulgarian waters.

The Maltese-flagged Chelsea 3 was also hit by three drones. Its entire crew survived: seven Ukrainians and eight Azerbaijanis. They were rescued, and none suffered serious injuries. The attacks therefore had sharply different outcomes, depending on the vessel and damage caused.

The episode followed another deadly sinking a week earlier. Ten sailors, including nine Syrians and one Egyptian, were lost then. Officials did not identify the attackers, but Bulgaria summoned Russia’s ambassador because the incidents occurred amid Russia’s war against Ukraine and benefited Russia, according to Prime Minister Rumen Radev.

A drone attack is an assault carried out by an unmanned aircraft controlled remotely or operating with onboard guidance. Drones can carry explosives or be used as flying impact weapons. They allow an attacker to threaten ships without placing pilots or sailors directly in danger.

A large cargo ship can still be vulnerable. An explosion may tear open the hull, damage engines, destroy steering equipment, or ignite fuel and cargo. Water entering through a breach can cause flooding and make the vessel unstable. Multiple strikes can worsen the damage quickly. The article reports that Chelsea 3 was hit by three drones, while HS Dignity sank.

The article does not specify the drones’ design, weapons, or exact damage mechanism. It does show the consequences: one ship sank, another was damaged, five sailors were rescued, and 11 remained missing. The attacks also disrupted shipping near Bulgaria.

At least four commercial ships were affected by drone attacks in the area within one week. Two were hit overnight near Bulgaria, and two more were hit during the previous week. One ship sank in each episode. This pattern shows that attacks were not isolated incidents for Black Sea shipping.

The article gives confirmed details for at least 41 crew members. The latest attacks involved 16 people on HS Dignity and 15 on Chelsea 3. The earlier sinking involved 10 sailors who were lost at sea: nine Syrians and one Egyptian. Another ship was hit that night, but the article does not state how many crew members were aboard or rescued.

Therefore, 41 is a minimum, not a complete total. The known outcomes include rescued sailors, missing sailors, and deaths or presumed losses. The repeated attacks have drawn commercial shipping further into the economic and military struggle surrounding Russia’s war in Ukraine.

Bulgaria summoned Russia’s ambassador because two commercial ships were attacked near its coast during Russia’s war against Ukraine. Prime Minister Rumen Radev called the incidents unacceptable and said their outcome “benefits the Russian Federation.” The location and timing made the attacks a direct national security concern.

The government did not explicitly state that Russia carried out the strikes. That distinction matters because responsibility had not been publicly established. Russian Ambassador Eleonora Mitrofanova said she had no information from Russia’s Defense Ministry and suggested a third party could have staged a provocation. Moscow had not immediately commented.

The summons was therefore a diplomatic response to suspected consequences, not a formal public finding of guilt. Bulgaria also sought stronger maritime and airspace surveillance from NATO. The EU and Ukraine condemned the attacks, while NATO Secretary General Mark Rutte said the alliance would adjust its eastern-flank presence as needed.

Territorial waters are the sea area next to a country’s coast where that country generally exercises sovereignty, subject to international law. An exclusive economic zone, or EEZ, extends farther offshore and mainly gives the coastal country rights over natural resources. It does not normally make the entire zone equivalent to national territory.

That difference matters here because Bulgarian officials described the latest attack as being near Bulgarian territorial waters. The previous week’s sinking occurred in Bulgaria’s Black Sea EEZ. The two locations carry different legal and political implications, even though both are close to Bulgaria and important for maritime safety.

The article does not provide exact distances or a legal ruling about either incident. In practical terms, an attack near territorial waters can feel like a more direct challenge to national security. An attack in the EEZ still threatens civilian shipping, economic activity, and regional stability. It also complicates responsibility and surveillance across a busy wartime sea.

Black Sea attacks can disrupt grain exports by making ships, crews, insurers, and ports face greater danger. Operators may delay voyages, charge more, or avoid routes altogether. Fewer shipments can reduce supplies in importing countries. That pressure can contribute to higher food prices, especially where buyers depend heavily on grain from Russia or Ukraine.

The article identifies both countries as among the world’s largest grain exporters. Russia has been bombing Ukrainian Black Sea ports, while Ukraine has increasingly targeted Russian grain-exporting ships elsewhere in the Black Sea and Azov Sea. These actions turn shipping routes into part of a prolonged economic battle, rather than ordinary commercial links.

The consequences can extend internationally. Ukraine’s foreign minister called the Black Sea a lifeline for global food security and accused Russia of weaponizing hunger. The article does not give price forecasts or quantities of lost grain. It does show that continued attacks could restrict trade, increase uncertainty, and pressure vulnerable food-importing countries.

If open-sea routes become too dangerous, Ukraine can shift more grain through its river ports on the Danube. It can also use shipping routes close to the coasts of NATO members Bulgaria and Romania. These options may offer greater proximity to protected coastlines, but the article does not say they are risk-free or provide their capacity.

Russia can continue using other parts of the Black Sea and the Azov Sea. The article says Ukraine has targeted Russian grain-exporting ships in those areas, including near the mouth of the Don River. That means Russia’s alternatives remain exposed to the wider conflict and may also face attacks or disruption.

The choices are therefore substitutions, not guaranteed solutions. River routes may be slower or limited, while coastal routes still pass through a militarized region. The article presents the growing reliance on Danube ports and nearby coastal shipping as evidence that the war is reshaping grain logistics and economic endurance.
