Story summary

On October 13, Prime Minister Rumen Radev of Bulgaria announced that two ships were attacked by drones off its Black Sea coast, with one sinking. The incident involved the Ukrainian-owned "Chelsea 3," which was sailing under Maltese flag and hit by three drones around 1:30 a.m. (2230 GMT), about 18 nautical miles from Bulgarian shores. All crew members were rescued; seven Ukrainians and eight Azerbaijanis, with five receiving medical assistance but no serious injuries reported.

Radev described the attack as "absolutely unacceptable," noting its proximity to Bulgarian territorial waters. Despite lack of clear evidence on who conducted the attack, he stated that it benefits Russia and planned to summon the Russian ambassador for discussions. As a NATO member, Bulgaria's strategic position on the Black Sea, near ports crucial to both Ukraine and Russia, underscores the geopolitical significance of such maritime incidents.
