Drones strike two commercial ships in Black Sea off Bulgaria, sinking one

Commercial shipping in the Black Sea faced renewed peril on Tuesday when aerial drones targeted two vessels off the coast of Bulgaria. The strikes resulted in the sinking of one ship and left another damaged, prompting urgent rescue responses and swift diplomatic fallout across European capitals.

Bulgarian Response and Diplomatic Actions

Prime Minister Rumen Radev addressed the nation following an emergency meeting of Bulgaria’s Security Council on Tuesday. Radev described the strikes as absolutely unacceptable actions occurring in the immediate vicinity of the country's territorial waters.

Radev stated that the Ukrainian-owned merchant ship Chelsea 3, sailing under a Maltese flag, was struck by three aerial drones. The vessel's 15-man crew—comprising seven Ukrainian citizens and eight Azerbaijani citizens—was safely rescued, with five crew members receiving medical treatment for minor injuries. Radev added that one crew member from the sunken vessel was also rescued.

During the security briefings, Radev announced plans to summon the Russian ambassador to Bulgaria, Eleonora Mitrofanova. While noting that authorities possessed no clear evidence pinpointing who carried out the attack, Radev remarked that logic suggested the outcome benefited the Russian Federation. He also confirmed plans to speak directly with NATO Secretary-General Mark Rutte.

International Condemnation and Attribution Disagreements

Western and Ukrainian leaders laid direct blame for the maritime escalation on Moscow. European Commission President Ursula von der Leyen denounced the strikes via social media, stating that the Black Sea had transformed into another front of escalation in Russia's war against Ukraine.

"The Black Sea has become another front in Russia’s war of escalation against Ukraine. This is unacceptable. Those responsible must be held to account."

Ukrainian Foreign Minister Andrii Sybiha similarly blamed Moscow for the attacks, stating that Russia's actions demonstrate a deliberate disregard for civilian lives and maritime security. Conversely, Bulgarian leadership maintained that there was no clear evidence on who was responsible, even as officials noted the outcome favored Russia.

Previous Incidents and Regional Context

Tuesday's strikes occurred exactly a week after a similar drone attack targeted two commercial vessels in Bulgaria’s exclusive economic zone in the Black Sea. During the earlier incident, a Togo-flagged vessel named the Alfa Vatan sank, while a Bulgarian ferry evacuated the 18-member crew of a Palau-flagged vessel.
