The war is expanding toward the Black Sea, placing NATO’s “red line” before a crucial test.
Sea-news.az reports citing an analytical article published by Reuters, that following seven strikes on cargo vessels last month near NATO members Romania and Bulgaria, the US-led military alliance announced plans to deploy maritime patrol aircraft, radars, and drones to reinforce its eastern flank in the Black Sea. Three days later, on October 23, another vessel was hit off the Romanian coast. Last week, a Greek-owned container ship was sunk by naval drones in Bulgaria’s exclusive economic zone.
The relentless attacks signal that the escalating maritime conflict between Russia and Ukraine has evolved into a major challenge for NATO in the Black Sea, directly threatening coastal member states such as Romania and Bulgaria. “In my view, this is undoubtedly an escalation,” stated Sidharth Kaushal, a research fellow at the London-based RUSI think tank.
Russia denies targeting Ukraine’s neighbors with drones, asserting that European governments are further fueling the conflict by providing military assistance to Kyiv. The Russian Ministry of Defense did not respond to Reuters’ request for comment on the matter.
Most of the vessels struck in October were anchored or transiting near the primary Romanian shipping canal utilized by Ukraine for agricultural and commodity exports. One vessel was positioned within Romanian territorial waters, while eight others were situated within the exclusive economic zones of Romania or Bulgaria.
Yulia Joja, director of the Black Sea Program at the Washington-based Middle East Institute, commented on the situation: “These attacks demonstrate that we must do everything possible to implement at least baseline countermeasures, while highlights the imperative to test these ‘red lines’.” She interpreted the incursions of Russian drones into NATO airspace in recent years as a direct challenge to those boundaries.
A NATO official reiterated that ensuring the security of member nations and protecting alliance borders remains the foremost priority.
The Black Sea serves as a vital trade artery for Romania and hosts the offshore Neptun Deep gas development project, which is set to position the nation as the European Union’s largest natural gas producer next year. While Bucharest has accused Russia of systematic strikes on commercial shipping, it has abstained from severe retaliatory actions citing the need for conclusive evidence. Sofia, meanwhile, has refrained from issuing direct accusations against Moscow.
The surge in Black Sea maritime attacks coincides with Washington’s broader reassessment of its military posture in Europe. The United States withdrew 1,000 troops from Romania last year.
