Drones sank two merchant ships and set a third on fire in the Black Sea economic zones of NATO members Romania and Bulgaria on 5 and 6 October, killing at least two seafarers, Romanian and Bulgarian authorities reported. Ukraine blamed Russia for the first attack. Neither Bucharest nor Sofia has said who launched the drones.

Russia has spent months striking ships bound to and from Ukrainian ports while denying responsibility or staying silent. Now merchant vessels are sinking inside NATO members' economic zones without either government naming the attacker, so Moscow pays no political price for hitting allied waters.

Grain ship sinks off Romania

The Royad Mammadov, a Turkish-owned ship carrying grain from Ukraine's port of Izmail to Italy, sank on 5 October near Romania's Pescăruș offshore platform, 20 nautical miles from the Romanian coast, Digi24 reported. The Romanian Naval Authority described the incident as a fire on board. Romania's Interior Ministry said 11 crew members were rescued and two people died.

Three injured sailors aged 22 to 50 were taken to the Constanța county hospital, conscious and stable, with multiple injuries. Adrian Mihălcioiu, the leader of Romania's Free Seafarers' Union, said the ship was attacked by Russian sea and aerial drones in waters Romanians consider safe.

"It is a commercial ship, a ship that is not part of the war… people who have nothing to do with the war, it is not their war," he said.

Ukrainian President Volodymyr Zelenskyy blamed the attack on "two Russian drones" and said the ship was in neutral waters carrying corn. Citizens of Azerbaijan and India were on board, and the captain was killed, he said. Romanian authorities have not attributed the sinking to Russia.

Two more ships hit in Bulgaria's zone

A day later, drones struck two merchant ships in Bulgaria's exclusive economic zone east of the town of Byala, the first known attack on ships there, Maritime.bg reported. The Togo-flagged Alfa Watan, sailing from Al-Arish, Egypt, to Sulina, Romania, suffered critical hull damage and sank, Militarnyi said. The Bulgarian ferry Dioscuria found only an overturned lifeboat and life jackets at the scene, and the search for the crew continues, Euronews reported.

The Palau-flagged Able, sailing from Galați, Romania, to Istanbul, caught fire, and the Dioscuria rescued its 18 crew members. Both ships are Turkish-owned, Türkiye Today reported. Two sailors with severe injuries were flown to a hospital in Varna, Prime Minister Rumen Radev said, according to AP. Sea and aerial drones hit the ships at about 3 a.m., he said, calling the attack "a blatant violation of international law and maritime law."

Radev called an emergency meeting of four ministries, the presidency, and the security services. No one from the Alfa Watan has been found, he said, warning that if the war is not ended in time, it "will continue to expand its spatial scope." The origin of the drones is still being clarified, Maritime.bg said. Several Bulgarian media outlets cited sources as saying the drones were Russian, Sofia Globe reported.

Russia's war on Black Sea shipping

Russia had already killed the captain of a Tanzanian-flagged ship in September, and days later it struck another civilian vessel, killing its captain too. Ukraine says that route carries 90% of its farm exports.

Romania has destroyed a sea drone near its Neptun Deep gas project and found Russian drones floating in its economic zone. In September, ISW linked drone crashes in Romania and Moldova to a wider Russian pattern of pressure on NATO.

EU foreign policy chief Kaja Kallas called for a moratorium on Black Sea attacks. Turkish President Recep Tayyip Erdoğan said Ankara was stepping up diplomacy to restore grain exports. Türkiye and the UN are organizing new Black Sea truce talks between Russia and Ukraine, Bloomberg reported, citing a diplomat. Russia earlier dismissed Kyiv's offer of a Black Sea ceasefire.

Russian FPV drones hit three ambulances and, separately, a residential high-rise in Kramatorsk late on 5 October, the Donetsk Oblast Prosecutor's Office said. The strike on the high-rise killed a woman and injured another, and three medical workers were wounded trying to save their vehicles. Prosecutors have opened war-crimes investigations.

Russian drones attack Ukrainian civilians every day, and Ukraine's UN envoy has cited "human safari" and repeat strikes on medics as grounds to strip Moscow of its Security Council seat. Kherson, Nikopol, and Kramatorsk are all cities where drone operators pick civilian targets in real time.

Drones aimed at ambulances

Between 22:00 and 22:25, the Russian army deliberately directed two FPV drones at ambulances parked on a Kramatorsk street, prosecutors said. Three workers of the ambulance service were injured while trying to save the vehicles after the first hit. They suffered blast injuries, shrapnel wounds to the body and limbs, burns, and concussions, and received medical care. Three ambulances were damaged.

FPV drones are flown by an operator watching a live camera feed until the moment of impact. Prosecutors called the strike targeted.

A woman killed at home

At 22:10, a Russian drone hit a residential high-rise in the city. A 49-year-old woman was killed. Another resident, a 68-year-old woman, suffered a broken foot, shrapnel wounds to the body and limbs, and a concussion, according to prosecutors. The Kramatorsk district prosecutor's office has opened criminal proceedings over war crimes.

Across Donetsk Oblast, Russian attacks killed three people on 5 October, in Sloviansk, Druzhkivka, and Sukhanivka, and injured 11, Donetsk Oblast head Vadym Filashkin said. His morning tally, posted before the prosecutors' report, did not include the Kramatorsk death.

Kramatorsk under the drone hunt

Russian drone operators have hunted people in Kramatorsk for months. In June, a Russian pilot chose to kill a man he saw on a city street. Russia strikes the city daily, and in August it dropped eight FAB-250 bombs on Kramatorsk, killing one person and injuring 18.

The same drone hunting of civilians has run for years in Kherson, where Ukraine's Security Service has named 10 Russian servicemen it ties to the "human safari." A UN inquiry has traced the Kherson campaign up the chain of command. In April, ISW found Russians using such tactics across southern Ukraine, including in Nikopol.

Medics have been repeated targets. In March, a Russian FPV drone killed two medics in an ambulance in Kharkiv Oblast, and in February, Russian drones hit an ambulance and a shop there, killing three. In Kyiv, a Russian missile attack damaged a maternity hospital in September.

The UN Human Rights Office verified some 15,280 civilian casualties in Ukraine during the first eight months of 2026, 55% more than in the same period last year, UN High Commissioner for Human Rights Volker Türk said on 2 October.

Türk's statement comes as Russia has begun its Winter 2026-2027 campaign of long-range strikes against Ukrainian energy infrastructure. The Institute for the Study of War (ISW) said Russian forces began the campaign in late September. Damage to energy infrastructure disrupt electricity, heating, and water supplies during the winter, increasing the risks to civilians.

Russian glide bombs killed and injured nearly 2,500 civilians in Donetsk, Kharkiv, Sumy, and Zaporizhzhia oblasts during the first eight months of the year, 62% more than in the same period last year, according to UN figures.

"As winter approaches, Ukrainians fear the worst is yet to come," Türk said.

On 4 October, Russia's Defense Ministry announced that it was intensifying strikes on infrastructure in Kyiv City and Oblast and across Ukraine, according to ISW.

Why Russia is turning to long-range strikes

ISW said Ukraine's 2026 battlefield successes "appear to be forcing" Russian President Vladimir Putin to shift focus from advances on the battlefield toward a winter campaign intended to compel Ukraine to surrender.

A week earlier, ISW assessed that Putin was likely attempting to force Ukraine to capitulate before spring 2027, with his theory of victory heavily relying on cheap, jet-powered Geran-type drones.

A toll rising all year

The 15,280 figure extends a trend the UN has tracked all year. Over the first seven months of 2026, its monitoring mission verified 1,839 civilians killed and 10,638 injured. In September, UN Under-Secretary-General Rosemary DiCarlo told the Security Council that more civilians were killed or injured in the first eight months of 2026 than in all of 2025.
