Six suspected Russian drone attacks occurred in ten days in the Black Sea.

Omissions

• The count rests on news reporting rather than a published official tally; no primary source (NATO, EU, Bulgarian or Romanian government) listing exactly six incidents within a defined ten-day window was located within the search limits.
• The claim is correctly hedged with 'suspected': formal attribution of all six incidents to Russian drones had not been established by an official investigation at the time of the statement.
• The ten-day window is an approximate, speaker-defined period rather than a statistical reference period; individual incidents occurred between roughly 8 and 18 October 2026.
