Bulgaria Under Scrutiny After Black Sea Drone Strikes on Ships

Two drone attacks in Bulgaria's Black Sea zone in October sank one commercial ship and damaged another. Military experts say the Bulgarian government has been slow to respond to spillover from Russia's war in Ukraine. Prime Minister Rumen Radev summoned the Russian ambassador, who suggested a third party might be responsible.
The incidents occurred on October 6 and October 13 in Bulgaria’s Black Sea zone, targeting commercial vessels. Reports indicate ships were sunk and damaged, while the number of deaths remained unconfirmed. Prime Minister Rumen Radev, a former air force commander, summoned Russian ambassador Eleonora Mitrofanova after the second strike.
Mitrofanova suggested a third party could be to blame. Radev said evidence did not clearly identify either side but noted the strikes appeared to benefit Russia. Former deputy defence minister Velizar Shalamanov criticized Bulgaria’s response as dangerously inactive, according to the report.
The strikes could heighten anxiety among Bulgarian coastal communities, shipping crews, and port workers, who may feel exposed to a conflict beyond their borders. Public debate may sharpen over whether Sofia’s response is adequate, potentially affecting trust in state institutions. Because Bulgaria is a NATO and EU member, the incidents may also draw more external attention to its security posture and ties with Russia, though the practical consequences remain uncertain.
