Six attacks on civilian ships occurred within ten days in early October in the exclusive economic zones of Bulgaria and Romania and in Romanian territorial waters.

Omissions

• The aggregate figure 'six ships in 10 days' is reported by The Guardian (2026-10-18); the individual attacks are independently confirmed by Reuters, France24 and Euronews, but no single official (primary) tally publishing exactly 'six attacks in ten days' was located.
• The attacks span roughly 6–16 October 2026 (from the first strikes in Bulgaria's EEZ on 6 October to strikes off Romania around 15 October); describing this as 'early October' is a slight imprecision, though the ten-day window begins in early October.
• Some coverage situates individual attacks at varying distances offshore and near the Ukrainian shipping corridor; the precise attribution of all six incidents strictly to Bulgarian/Romanian EEZ and Romanian territorial waters is drawn from media reporting rather than an official incident list.
