How to read this table
Reading aid only. Switch off a source or its recorded family to inspect the remaining visible support for exact claim texts. Evidence status is not recalculated. Shared wording or a shared family does not prove independence. Only recorded links labelled “supports” count here; context and contradiction links are not support. The dossier itself is unchanged.
| Claim | Supporting sources | Visible support |
|---|---|---|
| The Bulgarian prime minister confirms reported drone attacks on two commercial vessels. | [1] | Support remains visible |
| The Bulgarian prime minister's account confirms Alfa Watan sank after structural damage. | [1] | Support remains visible |
What we know
A Bulgarian ferry and a naval fast boat evacuated all 18 crew members of the Able; two were seriously injured and flown to hospital in Varna. The Alfa Watan sank within minutes. Media reports put its crew at 10 to 12, a number Bulgarian authorities did not confirm; Bulgaria called off the search on 7 October after finding an overturned lifeboat, three life rafts and debris. Early figures from Romania's interior ministry of two deaths and 11 people rescued were not confirmed by Bulgarian officials.
Drone involvement rests on the statement of Bulgaria's prime minister, whose country is not a party to the war, reported by Al Jazeera with AFP and AP; The Maritime Executive and Novinite report the ships, the rescue and the search. Sources give the distance from the coast as 70 to 80 nautical miles; The Maritime Executive gives the Alfa Watan's registry as Tonga rather than Togo.
