Two ships were hit by drone attacks off Bulgaria's Black Sea coast, resulting in one vessel sinking and another, the Ukrainian-owned Chelsea 3, sustaining damage. The Chelsea 3, sailing under a Maltese flag, was struck by three drones approximately 18 nautical miles off Bulgaria early Tuesday morning. Its 15-person crew, comprising seven Ukrainians and eight Azerbaijanis, was rescued, with five receiving medical assistance for minor injuries. Bulgarian Prime Minister Rumen Radev condemned the incident as "absolutely unacceptable" and noted that while the perpetrator is unclear, the outcome benefits Russia, leading to the summoning of the Russian ambassador. European Commission President Ursula von der Leyen also condemned the attacks, calling them unacceptable and a threat to Black Sea security.
