Story summary

On October 5, a fire broke out on the sinking 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 incident occurred near an oil platform operated by OMV Petrom.

A day later, on October 6, Bulgarian Prime Minister Rumen Radev announced that drones attacked two commercial vessels in Bulgaria's Exclusive Economic Zone (EEZ), about 80 miles off its coast. One of the ships, flying the flag of Togo and carrying an undisclosed cargo, sank after being hit by multiple drones, leaving its crew missing. The second vessel, which was flying the Palau flag, caught fire but all eighteen crew members were evacuated and two suffered severe injuries.

Ukrainian President Volodymyr Zelensky accused Russian drones of targeting civilian vessels in neutral waters, blaming Russia for a "horrific strike" on a Turkish ship carrying corn. The increasing frequency of drone attacks in the Black Sea underscores growing concerns about hybrid warfare tactics employed by Russia during its ongoing conflict with Ukraine.
