Quick Summary

Prime Minister Rumen Radev of Bulgaria reported that a merchant ship sank after being hit by drones off the country’s Black Sea coast, with another Ukrainian-owned vessel also struck but saved from sinking near Byala and Krapets on October 17th. One crew member was rescued in the first incident while all fifteen on the second were saved; however, one crew member of a different ship attacked last week is presumed dead. Radev summoned Russia’s ambassador over suspicions that Russian drones carried out these attacks, which have escalated tensions in the region amid ongoing naval conflicts between Ukraine and Russia.

Story summary

On October 13, two ships were hit by drones off Bulgaria's Black Sea coast, with one sinking and another sustaining damage. The Maltese-flagged "Chelsea 3," owned by Ukraine, was struck by three aerial drones approximately 18 nautical miles from the Bulgarian shore, damaging its deck and hull. All 15 crew members, comprising seven Ukrainians and eight Azerbaijanis, were rescued; five required medical attention but no serious injuries occurred.

Prime Minister Rumen Radev condemned the attacks as "absolutely unacceptable," stating they benefit Russia despite unclear evidence of perpetrators. He intends to summon the Russian ambassador for discussions regarding these incidents. The EU is considering Bulgaria as a strategic ally in its maritime security, particularly concerning commercial shipping routes through the Black Sea amidst escalating tensions related to Russia's war on Ukraine.

European Commission President Ursula von der Leyen also condemned the attacks, calling them an unacceptable escalation of the conflict and emphasizing that those responsible should face justice. NATO expressed readiness to support Bulgaria against such threats.
