Bulgarians vote on 25 October in a presidential election shaped by Russia’s war in Ukraine, attacks on Black Sea shipping and economic pressures. The contest between incumbent Iliana Yotova and reformist challenger Andrei Gyurov will also test the political authority of Prime Minister Rumen Radev.

Bulgaria will elect a president on Sunday, 25 October, in a contest that has become a test of the country’s relationship with Russia, its commitments to NATO and the European Union, and its response to deteriorating security in the Black Sea.

The Central Election Commission has registered 27 presidential and vice-presidential candidate pairs, although the contest is dominated by incumbent President Iliana Yotova and former caretaker prime minister Andrei Gyurov.

An opinion poll conducted by Market Links between 13 and 19 October placed Yotova ahead with 47.3 per cent support, compared with 30.6 per cent for Gyurov. However, low anticipated turnout makes a second round on 1 November highly likely.

Although Bulgaria’s presidency is primarily ceremonial, the office carries constitutional authority over defence, legislation and government formation. The election also comes six months after former President Rumen Radev secured a parliamentary majority and became prime minister, substantially changing the country’s political landscape.

A presidency shaped by political realignment

Yotova, 62, became Bulgaria’s first female president in January 2026 after Radev resigned to enter parliamentary politics. Previously his vice-president, she is now seeking a five-year mandate of her own.

Her candidacy is supported by Radev’s Progressive Bulgaria coalition, which won 131 seats in the 240-member National Assembly in April, as well as the Bulgarian Socialist Party. Her running mate is Kiril Valchev, director-general of the Bulgarian News Agency.

Gyurov, an economist and former deputy governor of the Bulgarian National Bank, is supported by the pro-European reformist opposition, including We Continue the Change and Democratic Bulgaria. His vice-presidential candidate is Georgi Kandev, a former senior Interior Ministry official.

A third significant contender is Kostadin Kostadinov, leader of the nationalist Revival party, whose political platform includes opposition to Western military assistance for Ukraine and closer relations with Moscow. His running mate is European Parliament member Petar Volgin.

The election follows years of political instability, during which Bulgaria held eight parliamentary elections between 2021 and April 2026. Radev’s parliamentary victory ended a prolonged period of fragmented governments, but it has also raised questions about the concentration of political influence.

A Yotova victory would place both the presidency and the parliamentary majority within the same political camp. A Gyurov victory would instead create an institutional counterweight to Radev’s government.

Russia and Bulgaria’s foreign policy divisions

Bulgaria joined NATO in 2004 and the European Union in 2007, but its relationship with Russia remains politically complicated.

Historical and cultural ties, including shared Orthodox traditions and the legacy of Bulgaria’s liberation from Ottoman rule, have influenced public attitudes towards Moscow. During the Cold War, Bulgaria was among the Soviet Union’s closest allies, and Russian influence continued after the collapse of communism, particularly through energy, business and political networks.

Russia’s full-scale invasion of Ukraine in February 2022 exposed divisions over whether Sofia should provide military assistance to Kyiv or adopt a more cautious position.

Since returning to power as prime minister in May, Radev has advocated maintaining Bulgaria’s European commitments while seeking improved relations with Moscow. His government has halted military deliveries to Ukraine and taken a more restrictive approach to further sanctions against Russia.

Yotova has similarly emphasised negotiations as the means of ending the war and warned against further militarisation of the Black Sea. Her position appeals to voters concerned that escalating confrontation could expose Bulgaria to additional security and economic risks.

Gyurov represents a more explicitly Euro-Atlantic political orientation, arguing for stronger Western alignment and institutional reform.

The contest therefore concerns not whether Bulgaria will formally leave its existing alliances, which would require decisions far beyond presidential authority, but how actively it participates in their policies towards Russia.

Black Sea attacks bring the war closer

The security debate has intensified following a series of drone attacks against merchant vessels operating near Bulgarian and Romanian waters in October.

According to a maritime threat assessment published by Ambrey, three commercial ships were struck on 5–6 October within the exclusive economic zones of the two NATO members. Two sank, marking a substantial escalation in the geographic exposure of commercial shipping.

Ambrey assessed that Russian forces were highly likely responsible and that the vessels had been targeted because of their connections to Ukrainian grain exports.

The attacks have raised concerns about navigation, maritime insurance, food exports and the potential for further incidents involving NATO member states.

Bulgaria’s position on the western Black Sea coast gives these developments particular significance. Its ports, maritime infrastructure and commercial shipping depend on maintaining secure access to international sea routes.

As EU Today previously reported, the expansion of Russian attacks into areas close to NATO territory creates difficult questions for coastal governments seeking to protect commercial interests without becoming direct participants in the conflict.

For Bulgarian voters, maritime security is no longer simply an aspect of the war taking place elsewhere. It has become a question of national security, economic vulnerability and the government’s capacity to respond.

Energy prices and economic concerns

The campaign has also been influenced by inflation and higher energy costs, particularly among lower-income households and residents of rural areas.

Bulgaria’s historical dependence on Russian energy has long complicated its foreign-policy choices. Although the country has pursued diversification, fluctuations in international energy markets continue to affect domestic prices and industrial competitiveness.

Economic concerns have acquired an additional dimension following Bulgaria’s adoption of the euro on 1 January 2026, making it the euro area’s 21st member.

The transition represents a significant stage in Bulgaria’s economic integration with the European Union, but it has occurred during a period of price pressures and uncertainty over household purchasing power.

The presidency does not determine energy policy or monetary decisions. Nevertheless, candidates’ positions on Russia, European integration and economic security form part of the wider political debate.

Why a second round is likely

Under Article 93 of Bulgaria’s Constitution, a candidate must receive more than half the valid votes, with turnout exceeding 50 per cent of eligible voters, to win in the first round.

Neither requirement is expected to be easily satisfied. Turnout in the first round of the 2021 presidential election was approximately 38.6 per cent, reflecting the broader problem of electoral participation after repeated national votes.

If no candidate meets the constitutional requirements on Sunday, the two leading candidates will contest a runoff on 1 November.

Yotova enters the election with a substantial polling advantage, but Gyurov could benefit from opposition voters consolidating around his candidacy in the second round.

The result will determine more than the occupant of the presidential office. It will indicate whether Radev’s parliamentary dominance can be extended to the presidency, or whether voters prefer a political counterweight at a time when Bulgaria faces growing pressure to define its position between Moscow and its Western allies.

The European Parliament has called for substantial additional funding for the European Union’s eastern border regions, proposing that up to 10 per cent of the budgets of relevant EU financing instruments be earmarked for areas affected by Russia’s war against Ukraine and growing security threats.

The resolution, adopted on Thursday, 22nd October, received 414 votes in favour, 79 against and 90 abstentions.

It seeks greater financial assistance for regions bordering Russia, Belarus, Ukraine and Moldova, as well as territories along the Black Sea, under the EU’s 2028–2034 financial framework.

The proposals include higher EU contributions towards infrastructure projects, additional investment in local economies and targeted assistance for communities experiencing declining investment, population losses and increased security costs.

However, the resolution is not binding legislation and does not itself allocate new funding. Its provisions must be incorporated into future budget agreements and individual EU spending programmes.

Eastern regions face economic and security pressures

Russia’s full-scale invasion of Ukraine has significantly changed economic conditions across the EU’s eastern frontier.

Border restrictions, disrupted trade routes, increased defence activity and uncertainty over regional security have affected investment and commercial activity.

The pressures are particularly apparent in Finland, Estonia, Latvia, Lithuania, Poland, Slovakia, Hungary, Romania and Bulgaria.

According to a European Parliament research briefing published in September, these regions face overlapping challenges involving economic decline, depopulation, inadequate infrastructure and higher expenditure on security.

Some communities previously depended on cross-border trade with Russia or Belarus, much of which has declined sharply following sanctions and restrictions introduced since 2022.

Other regions have experienced increased transport demand linked to Ukrainian refugees, military logistics and the movement of goods towards Ukraine.

The European Commission has recognised that conventional regional development programmes may not adequately address the combination of economic and security pressures.

Parliament proposes dedicated financial allocations

The resolution calls for up to 10 per cent of funding within relevant EU instruments to be earmarked for eligible eastern border regions.

This does not mean that 10 per cent of the entire EU budget would automatically be transferred to those areas.

Instead, Parliament wants targeted allocations within programmes covering regional development, agricultural policy, transport, industrial competitiveness and infrastructure.

MEPs also propose significantly higher EU contributions towards eligible projects.

Under the parliamentary position, certain projects could receive up to 95 per cent EU co-financing, reducing the amount that national or local authorities would have to contribute.

Projects connected with security, resilience or critical infrastructure could potentially receive funding covering 100 per cent of eligible costs.

Additional pre-financing would help local administrations begin projects without having to provide substantial initial expenditure.

The proposals are particularly relevant to municipalities with limited budgets and regions where private investment has declined.

Wider definition includes Moldova and Black Sea regions

Parliament has also proposed broadening the geographical criteria used to identify eligible territories.

The resolution covers regions bordering Russia, Belarus, Ukraine and Moldova, as well as regions with access to the Black Sea.

The proposed framework would use the EU’s NUTS 2 regional statistical classification.

For borders with Russia and Belarus, the parliamentary proposal includes geographical thresholds concerning the length of land or maritime frontiers.

For Romania, the revised approach could extend support to regions connected with Moldova, Ukraine and the Black Sea.

The proposals would also have implications for transport corridors linking Ukraine with the EU, including railways, ports, roads and border-crossing facilities.

Such infrastructure serves both civilian trade and military mobility requirements.

Existing programmes and new investment plans

The Commission has already introduced measures intended to support Europe’s eastern regions.

Its February 2026 strategy identified security, economic growth, connectivity, local industries and demographic resilience as principal areas requiring action.

A proposed investment initiative, EastInvest, is intended to facilitate financing through European and national financial institutions, with the potential to mobilise up to €28 billion by the end of 2027.

This would principally involve lending and investment support, rather than direct grants equivalent to the total facility value.

The Commission has also identified approximately €5.6 billion in cohesion funding redirected towards eastern border regions under the current financial framework.

Those reallocations form part of approximately €34.6 billion redirected towards new priorities across participating member states.

Parliament’s latest demands concern the period after 2027 and would operate separately from these existing arrangements.

Budget negotiations will determine the outcome

The proposal places additional pressure on governments negotiating the EU’s next long-term budget.

Agricultural policy, regional development and industrial investment are already competing for funding alongside increased European defence expenditure.

As EU Today reported in its coverage of the agricultural budget negotiations, member states remain divided over the allocation of resources under the next financial framework.

Eastern border governments are likely to argue that infrastructure and economic development in their territories contribute directly to the EU’s wider security.

Other member states may resist dedicated allocations if these require reductions in existing regional development programmes elsewhere.

Parliament has proposed that additional assistance should not come at the expense of support for other less-developed regions.

The negotiations will determine whether that position is financially achievable.

The next stage will involve discussions over the overall EU budget and the individual programmes through which eastern border assistance could be delivered.

For now, Thursday’s vote establishes Parliament’s demand for a larger and more clearly defined financial commitment to Europe’s eastern frontier, without creating an immediate entitlement to additional EU funding.

Mounting anxiety as Russia’s war on Ukraine reaches Nato’s borders with targeting of vessels transporting agricultural cargo

Nato is deploying additional military assets to the Black Sea amid the recent deadly escalation of Russian attacks on merchant shipping, as five more vessels were attacked on Tuesday.

Russia’s military said it ⁠struck ​three cargo vessels in Ukraine’s ⁠port of Reni and two ⁠other cargo vessels en ​route ‌to ‌Odesa.

The EU’s top diplomat has backed the idea of a Black Sea naval mission to protect grain ships from Russian drones – but this would require a much bigger effort than Europe’s existing Red Sea operation, while air-policing might be more effective.

“The EU should send a mission to the Black Sea,” said EU foreign affairs chief Kaja Kallas in the European Parliament in Strasbourg on Tuesday (20 October).

“To protect merchant shipping, not to escalate, not to scare anyone, but to make sure that we will supply safely fuel, merchandise at normal prices, anything we need. This is how it should be,” she said.

Some “six attacks in 10 days by suspected Russian drones marks a dangerous and unacceptable escalation,” in the region, Kallas added, with “rescuers
still searching for seven sailors missing after the drone attack on two tankers near Romania’s Black Sea coast”.

The Russian attacks were costing Ukraine €60m a day in lost exports of grain and fertiliser, Kallas also said.

And Russia had changed its tactics to start targeting people instead of cargo, said Sidharth Kaushal, from the Royal United Services Institute (RUSI) defence think-tank in London.

“Before, they targeted ports, not civilians, or vessels at sea. They realised that threat to life is a much more effective deterrent to commercial shipping than threat to cargo,” he told EUobserver.

A Sofia court has cleared European arrest warrants for two 19-year-old Germans charged with setting fire to Starlink antennas south of the Bulgarian capital, a court spokeswoman told dpa. Prosecutors named the pair in court, but both had already left Bulgaria. The case adds Bulgaria to a run of attacks on Starlink sites in Europe, which Poland and Lithuania have linked to Russia.

While Russia presses its assault along the front and strikes Ukraine’s cities, Starlink keeps Ukraine’s drone units and front-line troops connected, and Poland pays about $50 million a year for its terminals. The network’s ground links in Europe are now a target in their own right, and ISW has linked the Polish fire to a wider Russian pattern of sabotage. Each attack on a ground station hits a network whose speed caps already disrupted Ukraine’s drone missions this month.

Two names, a few hours in Bulgaria

Prosecutors identified the suspects as Zeka Islam and Tirpan Beytullah, Bulgaria’s state news agency BTA reported, noting the names may be misspelled. Their whereabouts are unknown, according to German authorities cited by the agency. They were charged in absentia on 14 October and face three to 12 years in prison if convicted.

According to the indictment, the two crossed from Serbia at the Kalotina checkpoint at 17:37 on 9 October and told border officers they were tourists. At about 22:25, wearing gloves and masks, they allegedly set fire to antennas at the Plana teleport, a satellite ground station near the village of Plana. They drove back into Serbia through the same checkpoint at 23:55.

Three antennas burned completely, two were partly damaged, and three more were affected, prosecutors say. The pair traveled in a Volkswagen with German plates, and a national warrant followed two days after the charges, ZDF reported.

The court-appointed lawyers argued that investigators had pinned down the vehicle, not the men in it. The court rejected those objections, finding reasonable grounds to suspect the pair. The lawyers said they would appeal. The ruling can be challenged within three days.

An opposition MP made the fire public three days later

The fire became public only on 12 October, when opposition MP Ivaylo Mirchev of Democratic Bulgaria posted about it on Facebook. He said 11 antennas had been set on fire, more than prosecutors later counted.

In parliament two days later, Prime Minister Rumen Radev asked the head of the State Agency for National Security (DANS) not to reveal details, saying disclosure could harm the investigation. DANS head Plamen Tonchev told lawmakers he believes the fire was sabotage and that more such attacks cannot be ruled out, dpa reported.

After the ruling, Mirchev wrote that Radev personally owes the public an explanation of what has been achieved, BTA reported.

Bulgaria’s case joins attacks Poland and Lithuania tie to Russia

Bulgaria has not said who might be behind the fire. Authorities in Poland and Lithuania have linked similar recent arsons on Starlink equipment to Russia.

In September, fire hit a Starlink ground station south of Warsaw, and Germany later detained two suspects. On 18 October, Lithuania’s prime minister said intruders had tried to burn a company’s Starlink antennas used by Ukraine, calling it part of Russia’s hybrid war. Moscow claims such accusations are baseless, Reuters reported.

Someone tried to set fire overnight to a Lithuanian company that stores Starlink communication equipment, but tipped-off guards foiled the attempt, Lithuanian Prime Minister Mindaugas Sinkevičius said. He linked the attack to Russia’s hybrid war against Europe. It is the third suspected sabotage of Starlink infrastructure in Europe in under a month.

Russia keeps attacking Ukraine at the front and from the air while running a sabotage campaign behind the lines in Europe, which ISW has linked into one pattern. Starlink keeps Ukraine’s drone units and front-line troops connected, and Poland pays for much of that service.

Fuel canisters and a control unit

The attack came just after midnight, the prime minister wrote. Security services had warned the company about possible attacks, security was stepped up, and the attempt failed.

The company provides connectivity through nine Starlink satellite antennas used by Ukraine, Sinkevičius told Lithuanian public radio LRT. At almost 2 a.m., intruders tried to burn the antennas and their control unit, leaving behind incendiary liquid in canisters of 3 to 10 liters.

“It is obvious that this is part of Russia’s hybrid war with elements of sabotage,” he said, adding that the client was likely “the Russian side.”

He said he believes the people involved, and how many there were, are known, but gave no details, citing the investigation.

Police Commissioner General Arūnas Paulauskas said no suspects had been detained, any damage was minimal, and the company kept working. A pretrial investigation is under way.

A drone the same morning

Hours later, an object that apparently entered from Poland crossed northern Lithuania, and NATO jets failed to identify it, Defense Minister Robertas Kaunas said. Possible fragments were found in the Pasvalys district near the Latvian border. Latvia’s military said the object may have blown itself up on a course toward Latvia.

Sinkevičius said the sabotage version had to be checked for the drone too. He called the National Security Commission for Monday, 19 October, to examine both incidents and consider giving services more powers to neutralize drones.

The third Starlink site

In September, a fire destroyed the distribution panel at a Starlink ground station in Wola Krobowska, Poland. Germany detained two Turkish nationals on 12 October, and Warsaw blamed Russian intelligence. In Bulgaria, masked intruders burned 11 of 17 Starlink antennas near Sofia.

Two tankers caught fire within about 12 hours off Sulina, Romania’s port at the mouth of the Danube, Romanian authorities reported. The crew of one said a drone hit it inside Romania’s territorial waters, while Bucharest says it is still checking whether drones were involved. Bulgaria, where drones sank ships in its economic zone this month, says it lacks proof that Russia launched them.

For months, Russia has struck civilian ships on the sea route that carries most of Ukraine’s farm exports, while its drones have repeatedly crossed into Moldova and Romania during attacks on Ukraine. As long as Bucharest and Sofia wait for drone wreckage before naming anyone, Russia, the party Bulgaria’s own prime minister says the logic points to, pays no price for extending its war on Ukraine’s trade routes into NATO members’ waters.

Seven sailors missing after the second fire

The San Marino-flagged chemical tanker Wine Trader reported a fire in its superstructure around 07:00 on 15 October while anchored in Romanian territorial waters about 13 nautical miles southeast of Sulina, Romania’s Naval Authority said. By midday, five of its 12 crew had been recovered and seven were still missing.

Hours earlier, at 01:34, a drone entered Romanian airspace over the country’s waters southeast of Sulina for about a minute before vanishing from radar, the Defense Ministry said. Authorities have not named a cause for the fire, though unnamed sources

Drone strikes against merchant vessels off Bulgaria have brought Russia’s war into waters bordering NATO and the European Union. With grain exports threatened, shipping costs rising and Sofia seeking allied protection, Moscow’s campaign against maritime trade risks becoming another instrument of economic and political pressure.

Russia’s expanding campaign against commercial shipping in the Black Sea is creating a security crisis that extends far beyond Ukraine. The latest drone attacks off Bulgaria’s coast have left 11 sailors missing, forced Sofia to seek assistance from NATO and the European Union, and raised concerns that Moscow is attempting to disrupt one of the world’s principal agricultural export routes.

On 13th October, the Guinea-Bissau-flagged HS Dignity sank after being struck by drones approximately 17 nautical miles east of the Bulgarian village of Krapets. Another vessel, the Ukrainian-owned, Maltese-flagged Chelsea 3, was attacked near Byala. All 15 crew members were rescued, although five sustained minor injuries. The incidents followed earlier attacks in Bulgaria’s exclusive economic zone on 6th October, when the ALFA WATAN sank and the grain-carrying ABLE was damaged.

The significance lies not simply in the destruction of merchant vessels but in the geographical expansion of the threat. Commercial routes previously regarded as comparatively safer alternatives to Ukraine’s exposed ports are now becoming operationally dangerous. Bulgaria and Romania, both NATO and EU members, face disruption to trade, maritime insurance and port operations as the conflict spreads across the western Black Sea.

Russia’s Campaign Against Maritime Trade

The latest attacks follow months of Russian strikes against Ukrainian ports, export terminals and civilian shipping. As EU Today previously reported, repeated attacks on Odesa have already reduced Ukraine’s grain-export capacity, while alternative routes through the Danube and neighbouring European countries cannot fully replace its major Black Sea terminals.

The extension of attacks towards Bulgaria changes the economic calculation. Ships carrying agricultural products, those approaching Danube ports and vessels operating between Black Sea countries now face greater uncertainty, regardless of whether they enter Ukrainian territorial waters.

Maritime security company Ambrey assessed the earlier October attacks as highly likely to have been conducted by Russian forces. Its assessment identified vessels associated with Ukrainian grain trade as the principal targets, rather than suggesting that every commercial ship was being attacked indiscriminately.

This distinction is important, but it offers little reassurance to international shipping companies. A campaign directed against Ukrainian trade can disrupt the wider maritime economy when insurers, shipowners and exporters cannot establish which routes remain safe.

The economic consequences are already becoming apparent. Shipowners must consider higher insurance premiums, additional security measures and the possibility of losing vessels and crews. Traders may redirect cargoes or withdraw from routes whose commercial returns no longer justify the risks.

Radev Confronts the Consequences of Moscow’s War

The attacks have also placed Bulgarian Prime Minister Rumen Radev in an increasingly difficult political position.

Radev has advocated renewed diplomatic engagement with Moscow and questioned the emphasis placed on military assistance to Ukraine. He has rejected accusations of being pro-Russian, presenting his approach as a pragmatic alternative to prolonged confrontation.

Yet the attacks have demonstrated the limitations of maintaining political distance from a war whose economic and security consequences are reaching Bulgarian waters.

After summoning Russian Ambassador Eleonora Mitrofanova on 13th October, Radev acknowledged that Bulgaria possessed no conclusive evidence establishing responsibility for the latest strikes. Nevertheless, he argued that their consequences benefited Russia and questioned why Ukraine would attack its own commercial vessels.

According to the Bulgarian News Agency’s account of the meeting, the prime minister also warned that higher insurance costs and shipping companies’ reluctance to serve Bulgarian ports were already damaging the national economy.

This is the fundamental change confronting Sofia. The conflict is no longer solely a question of Bulgaria’s position towards Ukraine or its diplomatic relationship with Russia. It is affecting the country’s commercial interests, energy supplies and responsibilities as a NATO member.

Radev’s response does not necessarily indicate a wholesale reversal of his previous political position. It demonstrates that the practical obligations of government can leave considerably less room for accommodation with Moscow than the arguments advanced from outside direct responsibility for national security.

Food Security Becomes Another Instrument of Pressure

The broader consequences may be felt most severely outside Europe.

Ukraine remains an important supplier of wheat, maize and vegetable oils to international markets, including countries in Africa, Asia and the Middle East. Interruptions to these exports affect more than Ukraine’s agricultural revenues. They can increase transport costs, delay deliveries and reduce the availability of competitively priced food in import-dependent countries.

Speaking at the Warsaw Security Forum on 12th October, President Volodymyr Zelenskyy warned of a possible agricultural crisis, arguing that Russian interference with Black Sea shipping could leave countries in Africa, Asia and the Middle East facing serious supply difficulties within months.

The warning reflects a mechanism already familiar from the earlier stages of Russia’s invasion. Following Moscow’s withdrawal from the UN-brokered grain agreement in July 2023, Ukrainian agricultural exporters faced renewed attacks on port infrastructure and substantial uncertainty over maritime access.

The danger is not necessarily an immediate worldwide shortage of grain. Wheat prices remained relatively steady following the 13th October incidents. Rather, sustained disruption could progressively reduce available export capacity, increase costs and place vulnerable importing countries under greater pressure.

For Moscow, such disruption could serve several purposes simultaneously: weakening Ukraine’s economy, raising the costs of international support for Kyiv and creating additional pressures on governments concerned about food inflation and social stability.

Europe’s Black Sea Security Strategy Faces a Practical Test

The immediate challenge for Brussels and NATO is how to protect commercial navigation without allowing the conflict to expand into a direct military confrontation.

Bulgaria has requested stronger air and maritime surveillance and is seeking closer coordination with Romania and Turkey. Defence Minister Dimitar Stoyanov said on 14th October that Sofia expected to join a NATO counter-drone initiative by the end of the month.

The EU has already developed a framework for addressing precisely such threats. Its Black Sea strategy, announced in May 2025, proposed a maritime security hub integrating surveillance, intelligence-sharing, infrastructure protection and regional cooperation.

The attacks now expose the difference between developing a security framework and providing effective protection to merchant vessels. Better intelligence can identify threats, but preventing further sinkings requires detection systems, coordinated responses and sufficient defensive capabilities.

Turkey’s involvement is particularly important because of its control over the Bosphorus and Dardanelles and its established role in Black Sea maritime security. Any workable regional arrangement must therefore extend beyond cooperation between Bulgaria and Romania.

The incidents occurred outside Bulgaria’s 12-nautical-mile territorial sea, meaning they do not automatically constitute an armed attack on NATO territory under Article 5. Nevertheless, repeated strikes within the economic zones of alliance members pose a substantial challenge to maritime security.

Russia’s campaign against Ukrainian exports is increasingly imposing costs on neighbouring European states and international trading partners. The question facing the EU is whether it can secure the commercial routes on which both Ukraine’s economy and the food supplies of millions beyond Europe depend.

Drone attacks on commercial shipping in the Black Sea on Tuesday sank one ship and damaged another. The cargo ship Dignity, a Guinea-Bissau-flagged vessel, was sunk. The Ukrainian-operated coastal freighter Chelsea, a Malta-flagged vessel, was disabled. Both ships were attacked approximately 20 miles off the coast of Bulgaria. Officials in Bulgaria, which joined NATO in […]

The Black Sea has become a new frontline between Russia and Ukraine, as the two agricultural powers join battle to halt each other’s exports.

On Tuesday (13 October), the Ukrainian-owned Chelsea 3, sailing under a Maltese flag, was struck by three drones only 30km off Bulgaria.

According to Bulgarian prime minister Rumen Radev, two ships were hit by drones, one of which sank.

The recent incidents underline the vulnerability of commercial shipping in a region where Russia and Ukraine depend on maritime routes for their international trade.

And on the coast, Bulgaria’s position is particularly sensitive, as a Nato member bordering the Black Sea.

EU Commission president Ursula von der Leyen condemned the attacks on social media, calling them an “escalation” of the Russian war in Ukraine.

Nato general secretary Mark Rutte also reiterated the alliance’s commitment to regional security. “Nato would continue working closely with its Black Sea allies and had strengthened its posture along the eastern flank,” he said.

Shipping route under pressure

For Ukraine, access to the Black Sea is essential to exporting grain, sunflower oil, metals and other goods.

Before Russia’s full-scale invasion, Ukrainian Black Sea ports handled exports worth more than $40bn (€35.74bn).

Russian attacks on port infrastructure and shipping have severely undermined this trade, while the threat of further strikes raises the cost and risk of operating in the region.

Severe problems with Ukrainian agricultural exports became apparent as early as August, when the country managed to export only 20 percent of the grain it had shipped during the same period the previous year.

“With grain, it is more difficult,” Ukrainian agriculture minister Taras Vysotsky said.

He added that Ukraine’s domestic market was not suffering for now. Although buckwheat could become scarce, the main challenge for Kyiv now is to be able to export the supplies before they perish.

And alternative routes offer only partial relief.

Ukraine has increasingly relied on Danube ports, including Izmail and Reni, with cargo moving towards Romania’s Constanța port before being transferred to larger vessels for international markets.

But this corridor is under growing pressure from low water levels on the Danube, congested terminals and also drone attacks.

Waiting times for vessels seeking access to the river have exceeded two weeks.

A week after two cargo ships were struck by drones off the Bulgarian coast, the attack was repeated even closer to our territorial waters with a similar outcome: one vessel was sunk, and another was abandoned by its crew, resulting in injuries and likely numerous fatalities. This is already having tangible consequences for Bulgaria. “Attacks […]

While authorities do not possess clear evidence on who was responsible for the drone attacks, “it makes no sense for Ukraine to destroy its own ships in the Black Sea."

While authorities do not possess clear evidence on who was responsible for the drone attacks, “it makes no sense for Ukraine to destroy its own ships in the Black Sea."

Bulgaria summoned Russia’s ambassador to Sofia after two ships were hit off the country’s coast, as concerns mount over the security of Black Sea shipping.

The Alfa Watan, a ship sailing under the flag of Togo, and the Able, a vessel flying the flag of Palau, were targeted by naval and aerial drones on Tuesday (6 October) morning in the Black Sea near the Bulgarian coast.

The Alfa Watan sank, and rescuers at the scene found only an overturned boat, life jackets, and fragments of the ship’s equipment, according to Bulgarian prime minister Rumen Radev.

The 18-member crew of the Able caught fire, but was successfully evacuated to the port of Varna.

“This is an unacceptable attack in Bulgaria’s exclusive economic zone,” Radev said after an emergency government meeting on Tuesday.

Bulgaria had discussed the drone attack inside the EU and Nato, he added.

It came after a drone also sank a Turkish-owned grain ship, the Royad Mammadov, killing two sailors, on Monday.

But even though Ukraine’s president Volodymyr Zelensky was quick to blame Russia, the perpetrators have not been formally identified yet, in a grey-zone conflict in which deniability is a tactic.

Russia and Ukraine have been escalating attacks on ships for several months in an effort to disrupt each other’s export economies.

And Moscow’s attacks have largely halted Ukraine’s maritime exports of agricultural products, while Kyiv’s attacks have forced Russia to seek alternative routes for exports.

“The situation in the Black Sea is increasingly concerning,” said EU Commission’s president Ursula von der Leyen on X on Tuesday.

Ukraine has “proposed concrete steps to de-escalate the situation”, also said Zelensky.

But for all his good will, the attacks were just part of a broader deterioration in Europe’s security environment, covering also Nato’s eastern and southern borders.

‘Shadow war’

For Czech president Peter Pavel, speaking to Czech daily Deník N on 22 September, the most imminent danger came from a false-flag attack in Estonia or Latvia, to test Nato’s resolve.
