Commercial drone strikes hitting merchant vessels near Black Sea territorial waters have escalated regional security risks, prompting former Bulgarian prime ministers, diplomats, and security officials to issue an open appeal for urgent defensive preparations. The Oct. 15, 2026, appeal warns that repeated attacks on shipping require immediate government action rather than political reassurance, as offnews.bg reported.
Black Sea Drone Attacks Target Commercial Shipping Near Territorial Waters
Recent maritime incidents include drone strikes against commercial vessels operating near the Romanian coast and close to Bulgarian maritime borders. The Comoros-flagged tanker CHILDREN J was struck by drones while traveling toward Ukraine in Romanian territorial waters, sparking a fire that forced the successful evacuation of its crew, News.bg reported. A separate vessel, the HS Dignity, also faced operational disruptions as adverse weather hampered search and rescue efforts for missing sailors, News.bg noted.
Kiril Petkov stated on Facebook that the strike on the tanker represents a direct attack on a NATO member state’s territory and threatens oil supplies destined for the Burgas refinery, according to News.bg. Petkov argued that initial government responses to shipping attacks were overly cautious and called for a clear ultimatum to Russian Ambassador Eleonora Mitrofanova, warning that any further strikes should result in her expulsion to Moscow, segabg.com reported.
Political Leaders Call for NATO Article 4 Consultations
Nikolay Denkov asserted during a bTV interview that none of the national security services expressed doubt that the attacking drones were Russian origin, bTV News reported. Denkov advocated for triggering Article 4 of the North Atlantic Treaty to demand urgent allied consultations, warning that the Black Sea is rapidly becoming a closed war zone, bTV News noted.
The open appeal coordinated by Ivan Anchev from the Atlantic Council of Bulgaria demands that the government explicitly condemn Russian military escalation, strengthen maritime and air surveillance, and accelerate anti-drone capabilities by utilizing Ukraine’s operational experience. Signatories to the document include Chavdar Chervenkov, Stefan Dimitrov, Dinko Ivanov, Valeri Rachev, Vesela Cherneva, Dimitar Ivanovski, Elena Poptodorova, Ivan Anchev, Ilian Vassilev, Orhan Ismailov, Radan Kanev, Stefan Tafrov, and Stoyan Stalev, offnews.bg reported.
Proposed Security Measures and Allied Coordination
Political figures have outlined concrete defensive steps to protect regional infrastructure. Petkov urged the activation of four immediate measures: convening NATO Article 4 talks, establishing a joint naval command between Bulgaria, Romania, and Turkey to escort oil tankers, issuing final warnings to Russian diplomats, and proposing European sanctions with direct confiscation mechanisms for Russian assets tied to Black Sea aggression, News.bg reported.
Denkov emphasized that Bulgaria must acquire advanced anti-drone systems and heavier defensive armaments equivalent to those deployed by allied nations, bTV News noted. The administration faced criticism from political opponents for exercising caution while assessing wreckage and debris from recent maritime explosions.
