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.
