A Russian drone strike sank the Comoros-flagged cargo ship Khoryv in the Black Sea near Romania’s port of Constanța on 23 October, killing a Ukrainian sailor and leaving three crew members missing. Nine others were rescued, Digi24 reported.

The sinking comes amid a surge in attacks on commercial shipping near Romania and Bulgaria, threatening civilian crews and routes used to transport Ukrainian agricultural exports. As Russia intensifies strikes on Ukrainian ports and shipping, the Danube corridor and nearby waters have become increasingly important to Ukraine’s maritime trade.

Romanian President Nicușor Dan blamed Russia for the attack, describing it as part of Moscow’s escalation of the war against Ukraine and its attacks on NATO’s eastern flank, Reuters reported. 

Ukraine’s Foreign Ministry confirmed to Radio Svoboda that a Ukrainian citizen was among those killed.

Ukrainian sailor killed, three crew members missing

The Khoryv sent a distress signal at around 10 a.m. local time, about 13 nautical miles (24 kilometers) east of Constanța, just outside Romania’s territorial waters, Digi24 reported. The vessel caught fire, sustained major damage, and capsized, with only a small part of its hull remaining visible above the water.

Romania’s naval authority said 13 crew members were aboard: 10 Ukrainians and three Azerbaijanis. Rescue teams recovered nine sailors alive and one body, while three crew members remained missing, Reuters reported.

Ukraine’s Foreign Ministry said the vessel had been traveling from a Turkish port and confirmed that the Ukrainian Embassy in Romania had received information from Romanian authorities about one Ukrainian sailor’s death. Four Ukrainian survivors, including the captain, were taken to a hospital, while two others did not require medical assistance.

Attacks threaten Black Sea shipping

The sinking comes amid a surge in attacks on commercial vessels off the coasts of Romania and Bulgaria. At least seven cargo ships have been hit over the past two weeks, with around 30 sailors reported dead or missing, according to Reuters.

The vessels targeted in recent incidents were either anchored near or heading toward the Sulina Canal, which connects the Danube River to the Black Sea. The canal has become a key export route for Ukraine, one of the world’s largest exporters of grain and vegetable oils.

Ukraine has increasingly relied on Danube ports and routes through Romanian territorial waters as Russia attacks its own Black Sea ports. Strikes on commercial vessels threaten crews and risk disrupting Ukrainian agricultural exports to international markets.

Russia has intensified attacks on Ukrainian ports and ships traveling to or from Ukraine. Moscow has described its strikes on vessels as retaliation for Ukrainian attacks on Russian or Russia-linked ships.

NATO plans stronger Black Sea surveillance

NATO said on 20 October it would send additional maritime patrol aircraft, radar systems, and drones to the Black Sea following the attacks on commercial shipping, according to Reuters. The alliance has not specified which capabilities it will deploy.

Romania, Ukraine, and Bulgaria have called on NATO to do more to protect commercial vessels. The latest sinking adds urgency to those calls as attacks increasingly affect shipping near NATO territory.

The latest incident highlights the growing risks to commercial shipping as Russia’s war against Ukraine increasingly affects maritime traffic beyond Ukraine’s own coastline.

German Foreign Minister Johann Wadephul has warned that disruptions to global shipping routes could trigger famine in vulnerable countries, citing Russian attacks on Black Sea shipping as part of the wider threat to international food supplies.

Russia has increasingly targeted civilian shipping in the Black Sea as part of its campaign against Ukraine’s maritime trade, striking cargo vessels, port infrastructure, and ships transporting agricultural goods. The attacks threaten Ukraine’s ability to export grain to global markets, raise risks for international shipping companies, and jeopardize food supplies in countries that rely on Ukrainian agricultural exports.

Speaking ahead of a meeting of foreign ministers in Istanbul on Friday, 23 October, Wadephul said attacks and threats to shipping in the Strait of Hormuz, the Red Sea, and the Black Sea were disrupting trade in food and fertilizers, DW reported. The impact extends far beyond the conflict zones, threatening countries that depend on imported wheat and agricultural inputs.

Wadephul said fertilizer shortages could threaten basic agricultural production in poorer countries, where access to imported food and farming supplies is already limited. He also pointed to Türkiye, the world’s largest wheat-processing country, as vulnerable to disruptions in the supply of grain.

Russian attacks disrupt Ukraine’s grain exports

Russia has intensified attacks on Ukraine’s Black Sea ports and civilian cargo ships, disrupting a maritime corridor that carries most of the country’s agricultural exports. In July, Russian strikes brought traffic through the corridor close to a standstill during the harvest season, leaving grain with fewer routes to international markets.

The attacks have also hit foreign-flagged vessels carrying or preparing to load Ukrainian grain. On 16 October, Euromaidan Press reported that Russian attacks had sunk merchant ships and damaged others in the Black Sea region, with seafarers missing. The campaign has increased risks for shipping companies and reduced the routes available for Ukrainian exports.

Ukraine is a major supplier of wheat and other agricultural commodities to global markets, including countries in the Middle East and Africa. Disruptions to its exports can tighten global supplies and push prices higher, adding pressure on countries that depend on imported grain.

Wadephul made the remarks ahead of a meeting of foreign ministers in Istanbul, where he said countries must send a signal that they will not accept Iran or Yemen’s Houthi militia holding global trade hostage. He called for an end to indiscriminate attacks on shipping and neighboring countries, warning that prolonged insecurity puts vulnerable populations at greater risk of hunger.

His remarks place Russia’s attacks on Ukrainian shipping within a wider pattern of threats to key maritime trade routes, with consequences for food security far beyond the regions directly affected.

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.
