Story summary

On October 5, a fire broke out on board the ship Royad Mammadov outside Romania's territorial waters in the Black Sea, resulting in two deaths and the rescue of eleven crew members. The Romanian Naval Authority confirmed that the vessel sank after the incident. While the cause of the blaze was not disclosed by authorities, Ukrainian President Volodymyr Zelensky accused Russian drones of targeting the ship.

On October 6, Bulgarian Prime Minister Rumen Radev reported that two commercial vessels were hit by drones in Bulgaria's Exclusive Economic Zone in the Black Sea. One Togo-flagged vessel sank with its crew missing, while another ship carrying grain had its entire crew of eighteen rescued. Two injured sailors from the latter were taken to a hospital in Varna. The origins of the drone attacks were unclear but there are concerns about hybrid warfare tactics used by Russia during its ongoing conflict with Ukraine.
