The Attack on Oct 6, 2026
On the early morning of Oct 6, 2026, sea- and air-borne drones struck two Turkish-owned cargo ships inside Bulgaria’s exclusive economic zone (EEZ) in the Black Sea, about 70 nautical miles (130 km) off Byala. The Togo-flagged Alfa Watan suffered critical structural damage and sank; the Palau-flagged Able caught fire but stayed afloat, allowing all 18 crew members to be rescued by a Bulgarian ferry. Two sailors from the Able were seriously injured and taken to a hospital in Varna. The Alfa Watan’s 12-member crew remains missing.
Background & Context
The incident follows a series of drone-related assaults on commercial shipping in the western Black Sea, including a Turkish-owned grain carrier that burned and sank off Romania on Oct 5. Since Russia’s invasion of Ukraine in February 2022, maritime authorities have recorded more than 200 attacks on civilian vessels in the Black Sea, with a sharp increase in 2024-2026. The attacks raise concerns about hybrid-warfare tactics that extend beyond the front lines of the Ukraine-Russia conflict.
