Summary

Two commercial vessels, the Alfa Watan and the Able, were struck by drones in Bulgaria's exclusive economic zone in the Black Sea on October 6, 2026. The Alfa Watan sank following an onboard explosion and now lies at an estimated depth of around 2,000 meters; the Able caught fire. Bulgarian Navy and border guard vessels rescued 18 crew members from the two ships, with two sustaining serious injuries including burns and a head wound. Ukrainian President Volodymyr Zelenskyy stated that Russian maritime and aerial drones carried out the attacks as part of Russia's campaign to disrupt shipping in the region. Bulgarian Prime Minister Rumen Radev characterized the incident as a breach of maritime law but stated that Sofia had not identified the source of the drones, noting they could have originated from either Russia or Ukraine and that the incident does not provide grounds for invoking NATO's Article 4 or 5. The Russian Embassy in Sofia denied responsibility. Defence Minister Dimitar Stoyanov observed that the strike came from an underwater drone. The origin of the drones remains disputed, with European Commission President Ursula von der Leyen condemning the attacks on civilian shipping as unacceptable.
