Story summary
On October 5, a fire broke out on the Royad Mammadov outside Romania's territorial waters in the Black Sea, leading to two deaths and rescuing of eleven crew members. The ship was reportedly carrying grain from Izmail, Ukraine, bound for Ravenna, Italy. Romanian officials did not provide details about the cause of the blaze or rule out involvement by drones. Ukrainian President Volodymyr Zelensky accused Russian drones of targeting the civilian vessel.
The following day, October 6, another incident occurred near Bulgaria's coast where two commercial vessels were hit by unidentified drones within its Exclusive Economic Zone. One ship, flying the Togo flag, sank with missing crew members, while a second ship was evacuated successfully with 18 rescued sailors, including two injured individuals flown to hospitals in Varna. Prime Minister Rumen Radev of Bulgaria described this as an unacceptable attack amid escalating tensions and drone warfare due to Russia's war on Ukraine.
