A series of drone attacks on commercial shipping near Romania and Bulgaria has left sailors dead or missing, bringing Russia’s war against Ukraine closer to NATO territory. The European Parliament is calling for an EU naval mission, while Romania has begun shooting down hostile drones and NATO is preparing additional defensive measures.

The European Parliament has called for the possible deployment of an EU naval operation in the Black Sea following a series of deadly attacks on civilian merchant vessels near the Romanian and Bulgarian coasts. The resolution, adopted on 22 October 2026 by 432 votes to 52, with 88 abstentions, reflects mounting concern over the expansion of maritime threats towards NATO’s south-eastern flank.

The parliamentary resolution urges EU member states to consider establishing a naval mission to protect commercial shipping, while calling on NATO to examine a complementary regional initiative, provisionally described as Black Sea Sentry.

On 23 October, a drone struck the Comoros-flagged cargo vessel Khoryv, approximately 13 nautical miles from Romania’s port of Constanța. The vessel caught fire and sank, leaving one sailor confirmed dead and three missing. Nine crew members were rescued. The ship was carrying 13 Ukrainian and Azerbaijani sailors. According to information attributed to Romanian maritime authorities, difficult weather complicated rescue efforts.

Romanian President Nicușor Dan blamed Russia for the attack, which followed at least seven other strikes on commercial vessels during October. Across the incidents, approximately 30 sailors have been reported dead or missing, although the confirmed death toll is considerably lower.

Civilian Shipping Under Attack

The escalation began on 5 October when the Royad Mammadov, a Turkish-owned grain carrier sailing under the flag of Saint Kitts and Nevis, sank in Romania’s exclusive economic zone. Two sailors died and eleven were rescued. The vessel had departed the Ukrainian Danube port of Izmail carrying corn destined for Ravenna, Italy. Ukrainian President Volodymyr Zelenskyy attributed the sinking to Russian drones, although Romanian authorities did not initially establish responsibility.

The following day, two merchant ships were attacked approximately 70 nautical miles east of the Bulgarian coastal town of Byala. As EU Today reported, the Togo-flagged Alfa Watan sank after sustaining severe damage, while the Palau-flagged Able caught fire. All 18 sailors aboard the latter vessel were rescued, but the crew of the Alfa Watan remained unaccounted for.

The Bulgarian authorities confirmed that both aerial and maritime drones had been involved. Further attacks followed on 13 October, when the HS Dignity sank near Shabla, leaving eleven sailors missing, while the Chelsea-3 was struck near Byala. All 15 crew members of the latter vessel were evacuated.

Two chemical tankers, the Yara J and Wine Trader, were subsequently attacked near the Sulina Canal, a strategically important route connecting the Danube with the Black Sea. The incidents exposed the vulnerability of shipping corridors connecting Ukraine with international markets.

Romania Moves Towards Active Military Defence

Romania has responded by strengthening surveillance and authorising direct military action against drones entering its airspace. On 17 October, two Romanian F-16 fighter aircraft intercepted and destroyed hostile drones over Romanian territorial waters.

According to the Romanian Ministry of National Defence, the aircraft were scrambled from Borcea Air Base after radar systems detected aerial targets approaching from the direction of Snake Island. The drones, identified as jet-powered Geran-family attack aircraft, entered Romanian airspace before being destroyed southeast and east of Sulina.

The ministry disclosed that, during the preceding week, its radar systems had detected eight separate incidents involving aerial targets near the Romanian border, including four brief incursions into national airspace. On 14 October, Spanish F-18 aircraft operating under NATO air-policing arrangements were scrambled after drones approached Romanian airspace.

Bulgaria’s More Cautious Response

Bulgaria has taken a more reserved position concerning responsibility for the attacks. Although Prime Minister Rumen Radev acknowledged their seriousness, his government maintained that investigations must establish the origin of the drones before definitive conclusions could be drawn. Sofia nevertheless strengthened maritime surveillance, deployed rescue resources and requested assistance from European and NATO partners.

In August, a drone crossed into Bulgarian airspace from Romania and exploded near infrastructure associated with the Trans-Balkan Gas Pipeline. According to the Bulgarian government’s account, the aircraft was not detected by either national radar systems or NATO’s Combined Air Operations Centre in Torrejón, Spain. The European Parliament has now urged Sofia to accelerate participation in NATO’s counter-drone initiatives.

EU Proposes Maritime Security Operation

The European Parliament’s proposals include establishing an EU naval operation, improving early detection of hostile drones, accelerating the development of a Black Sea Maritime Security Hub and providing additional defence funding to Romania and Bulgaria. MEPs have proposed using resources under the EU’s SAFE defence financing instrument to support regional capabilities.

The proposed hub would facilitate intelligence-sharing, maritime surveillance and protection of critical infrastructure. Romania and Bulgaria have requested EU satellite imagery to improve their awareness of maritime threats, while the European Maritime Safety Agency has offered additional support.

At their October summit, EU leaders condemned attacks on civilian shipping and called for safe passage for vessels transporting agricultural products. The European Council’s conclusions addressed Black Sea and Danube shipping routes. However, the parliamentary resolution does not authorise a naval deployment: such an operation would require agreement among EU governments on its mandate, resources and rules of engagement.

NATO Faces an Expanding Security Challenge

NATO has responded by examining additional maritime surveillance and defensive measures, including patrol aircraft, radar systems and unmanned platforms. Romania has proposed stronger regional command arrangements involving NATO’s Black Sea members.

An existing framework provides a basis for cooperation. In July, Romania, Bulgaria and Türkiye agreed to expand the responsibilities of their joint mine countermeasures task group to include protection of critical underwater infrastructure. The agreement announced by Romania’s Defence Ministry extended cooperation beyond detecting and neutralising drifting mines.

Protecting commercial vessels against aerial and maritime drones would require broader capabilities. NATO must also operate within the restrictions of the 1936 Montreux Convention, which regulates passage of warships through the Turkish Straits and limits deployments by non-Black Sea countries. Romania, Bulgaria and Türkiye would therefore play central roles in any sustained maritime security operation.

Black Sea Security and the Risk of Escalation

Ukraine’s maritime export corridors remain essential to agricultural shipments following repeated Russian strikes on ports and logistics infrastructure. Attacks on commercial vessels can increase insurance costs, discourage shipping companies and disrupt trade even when port facilities remain functional.

The sinking of merchant vessels near allied territory, combined with repeated drone incursions into Romanian airspace, increases the possibility of military confrontation arising from an individual incident. The legal and military circumstances differ depending on whether an attack occurs in territorial waters, an exclusive economic zone or international waters.

The European Parliament’s proposal raises questions extending beyond maritime patrols: how civilian shipping can be protected, what military responses are authorised and how responsibility for attacks will be established. The sinking of the Khoryv on 23 October illustrates how the western Black Sea has become an increasingly exposed part of Europe’s security frontier.

European Union leaders will meet in Brussels on 15–16 October under pressure to address surging energy costs, Russian hybrid attacks, continued support for Ukraine and the bloc’s next long-term budget. The summit comes as economic pressures expose growing differences between national governments.

European Union leaders are preparing for a two-day summit in Brussels dominated by the economic consequences of the Middle East conflict, Russia’s continuing war against Ukraine and mounting pressure on governments to reconcile defence commitments with deteriorating public finances.

The European Council meeting on 15–16 October will bring together the leaders of the 27 member states to consider immediate measures addressing high energy prices alongside longer-term decisions on competitiveness, enlargement, migration and the EU’s budget for 2028–2034.

European Council President António Costa has placed economic competitiveness and energy costs at the centre of the discussions, reflecting concerns that the disruption of global oil and gas markets is threatening the bloc’s industrial recovery.

The meeting also takes place against the background of renewed disputes over national spending limits, with Italy and Greece seeking greater freedom to finance energy relief and France facing increasing pressure over the credibility of its budget.

Energy crisis puts fiscal rules under pressure

The Middle East conflict has created a renewed energy shock for European economies, raising transport and industrial costs while pushing inflation higher.

The disruption of shipping through the Strait of Hormuz has also affected global oil supplies, exposing Europe’s continuing dependence on internationally traded fossil fuels despite efforts to diversify imports following Russia’s invasion of Ukraine.

European leaders are expected to consider targeted and temporary support measures for households and businesses, as well as longer-term policies intended to reduce energy dependence.

The political disagreement concerns how those measures should be financed.

The European Commission has resisted requests from Italy and Greece for further exemptions from the EU’s fiscal framework. Both governments argue that extraordinary energy costs require additional budgetary flexibility.

Brussels maintains that existing provisions already permit exceptional expenditure within defined limits.

The disagreement is particularly difficult for indebted governments that must simultaneously finance military expansion, maintain public services and protect their economies from energy inflation.

France’s position has added urgency to the debate. Its borrowing costs have increased sharply as investors question whether the government can adopt a credible budget ahead of the 2027 presidential election.

A summit agreement on emergency energy assistance would therefore have to accommodate substantially different national fiscal circumstances.

Ukraine and the changing transatlantic relationship

Support for Ukraine remains a central item on the summit agenda as Russia continues attacks against Ukrainian cities, energy infrastructure and industrial facilities.

EU leaders are expected to review military and financial assistance, the implementation of sanctions against Moscow and the resilience of Ukraine’s economy.

The discussions take place amid renewed uncertainty surrounding American weapons deliveries.

Washington’s reported threats to suspend supplies under the NATO-backed PURL procurement arrangement have raised further questions about Europe’s dependence on the United States for advanced military equipment.

European governments have increased defence expenditure and committed additional support to Ukraine, but replacing American capabilities remains difficult, particularly in air defence, precision-guided weapons and certain intelligence systems.

The summit is unlikely to resolve those industrial limitations, but the broader question of Europe’s ability to sustain Ukrainian defence over several years will influence discussions.

Member states must also consider how increased defence expenditure will be financed alongside other demands on national budgets.

Russian hybrid operations move higher on the agenda

The EU’s published summit agenda includes Russian-linked hybrid attacks within Europe.

The issue has gained prominence as European governments investigate sabotage, cyber operations, information interference and threats against infrastructure and defence-related industries.

Recent warnings concerning possible Russian assassination operations targeting European defence executives and employees of companies supplying Ukraine illustrate the changing nature of the security threat.

Such activities place additional demands on national intelligence services, police forces and European institutions responsible for cross-border cooperation.

The EU has strengthened its sanctions instruments against hybrid activities, but enforcement remains dependent on coordination between national authorities.

Any further measures would need to address intelligence sharing, protection of critical infrastructure and the relationship between internal security and the Union’s wider Russia policy.

A larger EU with a contested budget

Enlargement will form another important part of the discussions following the Commission’s proposals for preparing a wider Union.

Brussels has outlined possible institutional safeguards intended to prevent future members from undermining democratic standards or blocking common decisions.

Montenegro and Albania are advancing through their accession negotiations, while Ukraine and Moldova remain central to the EU’s geopolitical enlargement strategy.

The financial implications will become increasingly important as governments negotiate the next multiannual financial framework covering 2028–2034.

Existing members are already divided over how much the EU should spend, which programmes should receive priority and whether additional common resources should be raised.

Agricultural expenditure, cohesion funding, defence investment and support for Ukraine will compete for resources within the same budget negotiations.

The Commission argues that enlargement can be accommodated through targeted reforms, but securing agreement among member states will require decisions on future expenditure and the distribution of financial benefits.

Competitiveness and the single market

Leaders will also examine progress on the One Europe, One Market agenda, which aims to reduce barriers to economic activity within the EU and improve conditions for European businesses.

The initiative is intended to address structural weaknesses affecting investment, industrial development and the ability of European companies to compete internationally.

High energy prices have made those concerns more immediate, particularly for industries competing against producers in economies where electricity and fuel are cheaper.

The European Council will be asked to provide direction on measures planned for 2026 and 2027, but implementation will depend on subsequent legislation and decisions by member states.

The October meeting brings several unresolved European policy questions into the same negotiation: how to protect economic competitiveness, maintain fiscal credibility, finance defence, sustain Ukraine and prepare for enlargement.

The immediate test will be whether leaders can agree on a credible response to energy prices without reopening broader disputes over national budgets.

More difficult decisions concerning defence financing, institutional reform and the EU’s long-term expenditure commitments will extend well beyond the two-day summit.
