Maritime strikes hit NATO territory
The October 14 drone attack on the Comoros-flagged tanker Yara J near the port of Sulina landed in Romania’s territorial waters rather than its exclusive economic zone, an escalation that Dimitar Bechev says could trigger a NATO Article 5 response. This strike marks the first time a Russian drone has entered Romanian territorial waters. Seven ships faced hits from aerial and underwater drones this month along the same stretch of EU and NATO coastline. These attacks killed or left 27 crew members dead or missing. Two vessels sank off Bulgaria following attacks on October 6 and 13, and Sofia ended the search for the Alpha Watan crew less than a day after the vessel went down.
| Incident Data | Count/Details |
|---|---|
| Crew dead or missing this month | 27 |
| Romanian drone incursions this year | 35 |
| Bulgarian vessel sinkings in October | 2 |
| Romanian drones shot down this year | 6 |
Russia’s campaign against Ukraine’s sea trade now reaches NATO members. Grain ships leaving the Romanian river port of Galati have also been hit. Odesa, Chornomorsk, and Pivdennyi handle 95% of Ukraine’s grain exports, and these ports face threats from strikes. Container traffic at Odesa has already stopped and shifted to the Danube, feeding a food price shock on world grain markets. US restrictions reduced Ukraine’s access to early-warning intelligence, while interceptor stocks ran low and the Trump administration reportedly throttled Starlink satellite access. Kyiv faces risks to $10 billion of farm exports, which led the government to ask Ankara for help. Turkish Foreign Minister Hakan Fidan warned that the Black Sea must not become a new front.
Unrest in Bulgaria and Romania
Romania reports at least six drone incursions by Russia, and its F-16 fighters shot down two drones over its territorial waters on October 17. Romania has logged 35 unauthorized drone incursions this year, compared to nine in 2025, and has shot down six. Earlier in August, Romania shot down its fourth Russian drone. Bulgaria has also suffered from the campaign onshore. Weapons depots exploded in August and September, including a fire at an EMCO ammunition depot that investigators treated as possible sabotage. On the night of October 9-10, arsonists set fire to 11 antennas at a Starlink facility near Sofia, and investigators issued arrest warrants for two German nationals suspected of the arson.
Bulgaria faces internal political pressure regarding its relationship with Moscow. Prime Minister Rumen Radev advocates for restoring economic ties with Vladimir Putin and warned Europe against escalation. Caretaker President Iliana Yotova also holds these views and leads the polls ahead of the October 25 presidential election. Despite these positions, both Radev and Yotova have asked for a larger NATO presence in the Black Sea. Bulgaria’s defense minister announced the country will join NATO’s anti-drone initiative, reversing a previous refusal. Sofia has asked allies for aircraft, air policing support, and surface-to-air missile systems.
NATO responds to regional pressure
The North Atlantic Council meets in Brussels on October 20 to discuss expanding NATO military presence and surveillance in the region. Romanian Foreign Minister Oana Toiu says the council meets at the request of Bucharest and Sofia. Neither country has invoked Article 4 to trigger formal consultations regarding territorial integrity. Dimitar Bechev argues that Russia has "crossed another red line" and proposes broadening the mandate of the Turkish-Romanian-Bulgarian mine-clearance naval mission to monitor all three countries’ territorial waters and enforce freedom of navigation. He also suggests stepping up NATO air policing over the Black Sea.
The European Council condemned the attacks on civilian shipping and called for the restoration of navigation. The EU struggles to deter hybrid attacks pitched below the Article 5 threshold because security services still cooperate poorly across borders and the division of labour between the EU and NATO remains unsettled. Turkey can play a diplomatic role through its ties to Moscow. A show of strength will not necessarily solve the problem, as Bechev notes a show of force might only contain the strikes deeper into the Romanian and Bulgarian exclusive economic zones. It falls to Ukraine and its Western allies to find a counter to Russia’s drones and restore commercial shipping out of Odesa and other ports.
