Bulgaria / 2026-10-13-bg-1
/ date of the event
Early on 13 October 2026, Chelsea-3, flying Malta’s flag, was attacked in Bulgaria’s exclusive economic zone. According to the transport ministry, the attack took place around 01:15 local time, about 17 nautical miles east of Byala. All 15 crew members were rescued; the damaged vessel anchored. Its sinking is not confirmed. Reports of crew injuries differ; a final injury toll is undetermined. The prime minister’s early account described three aerial drones, while other reports suggest surface devices; the type, model and exact count remain unresolved. On 13 October, Bulgarian Defence Minister Dimitar Stoyanov said the devices were not clearly identified but he suspected the Russian side. This is an officially expressed suspicion concerning the series, not an established investigation finding. Bulgaria’s EEZ lies outside its territorial sea. Exact coordinates are undetermined; the entry has no map point. According to Maritime.bg, quoting the transport ministry on 16 October, securing and towing operations were still in progress. The anchor stabilised Chelsea-3; bad weather suspended operations on 15 October and Chelsea 2 was due to join on 16 October. Completed towing or arrival in port is not confirmed. This is the vessel’s subsequent fate, not a new attack. Its later drift position is not the site of the 13 October attack. Chelsea-3 arrived at Burgas on 17 October after towing whose main phase began on 16 October at 20:25. Inspections began; divers’ work was also reported on 18 October. The military prosecutor initiated pre-trial proceedings on 16 October. Transport Minister Georgi Peev said on 17 October that the attack most likely came from Russia but that this must be proved. This remains official suspicion, not a completed finding. Three visible hull breaches do not establish three drones or their model. Arrival and inspections concern the vessel’s fate after the 13 October attack, not a new attack. On 20 October, Bulgaria’s prime minister reported drone debris found aboard Chelsea-3 and chemical analyses of explosive material. He announced that experts from allied countries were expected on 21 October; their arrival and results are not yet confirmed. The defence minister referred questions to the military prosecutor. The device type, model, exact count and operator remain undetermined. Grade C suspicion and the attack date of 13 October are retained; inspections do not create a new incident. On 4 November AP reported that three drones struck Chelsea-3 and that all 15 crew were rescued. The prime minister’s earlier account also mentioned three drones. The exact number of devices and their operator remain unresolved.
