Drones Sink Cargo Ship Off Bulgaria, Killing Search for Survivors as NATO Allies Demand Answers

VARNA, Bulgaria, For the second Tuesday in a row, drones struck commercial ships off Bulgaria's Black Sea coast. This time the toll was worse.

The Guinea-Bissau-flagged cargo ship HS Dignity sank in the early hours of 13 October after taking a direct hit roughly 21 miles from shore, according to Al Jazeera. Five sailors were pulled from the water. Eleven remain missing. A parallel strike the same night caught a second vessel, the Maltese-flagged Chelsea 3, with three drones hitting it about 20 miles out. All 15 of its crew were evacuated, five of them treated for minor injuries.

Bulgarian Prime Minister Rumen Radev convened an emergency session of the country's Security Council before dawn and called the attacks "absolutely unacceptable," according to reporting by the Washington Times. He then summoned Russia's ambassador to Sofia and told her directly: it makes no sense for Ukraine to destroy its own ships in the Black Sea, and the results of these strikes favour Russia's interests. The ambassador said she had no information from the Russian defence ministry and did not rule out what she described as a provocation by a third party.

The pattern is now difficult to dismiss as coincidence. Exactly one week earlier, sea and aerial drones struck two other commercial vessels in Bulgaria's exclusive economic zone, sinking a Togo-flagged ship and forcing the evacuation of an 18-member crew from a second vessel, the Washington Times reported. The day before Tuesday's attacks, a Turkish-owned cargo ship carrying corn sank off Romania's coast after a separate drone strike, killing two people.

Bulgaria is a NATO member. Its coast, and the exclusive economic zone stretching out from it, is alliance territory in everything but the literal text of Article 5. Radev has now said Sofia will open talks with Romania and Turkey on joint proposals to guarantee shipping safety, and he confirmed the country is suffering significant economic and financial damage. European Council President Antonio Costa, for his part, said EU leaders would take up the rising tempo of what he called Russian hybrid activities at a summit in Brussels on Thursday and Friday, as reported by the Washington Times.

The strikes land at an especially delicate moment. On Saturday, US President Donald Trump posted on social media that an "energy ceasefire" between Russia and Ukraine was effective immediately and that both parties had agreed to it. Neither Kyiv nor Moscow confirmed the deal beforehand. Ukrainian President Volodymyr Zelenskyy told reporters he learned of it through the media, and by Sunday evening Russian drones had struck a power plant on the outskirts of Kharkiv, according to Al Jazeera.

Speaking by video link to the Warsaw Security Forum on Monday, Zelenskyy said Russia had already violated the truce and warned that Ukraine would respond if the attacks continued. He said Ukraine was waiting for Washington to clarify what, precisely, it had agreed to with Moscow and what steps it was prepared to take to enforce compliance. Kremlin spokesman Dmitry Peskov confirmed that talks were ongoing but pointedly rejected any full ceasefire, saying Russia wanted long-term peace rather than a temporary halt.

The EU, meanwhile, moved in the other direction. Ukraine's European allies voiced open scepticism about the energy ceasefire and approved what Al Jazeera described as the largest set of European Union sanctions since Russia's 2022 invasion, expanding the list to approximately 1,600 individuals and organisations, according to RTL as cited in the Rio Times Europe Intelligence Brief.

For Bulgaria, the abstract language of hybrid warfare has become very concrete: two consecutive Tuesdays, two ships down, and a rescue coordination chief who told reporters last week, after the first incident, that there was "no trace of the sailors." Radev is now asking Brussels and NATO to help with both the investigation and with keeping the shipping lanes open. Neither institution has said how, or whether, it can.
