Black Sea Ship Attacks: Two Sinkings in NATO Waters, and Russia's War on the Grain Fleet

In brief: Russian drones sank a Turkish-owned grain carrier inside Romania's exclusive economic zone on Monday, and two more merchant ships were hit off Bulgaria before dawn Tuesday, one now on the bottom with its crew missing. At least nine merchant vessels have been struck in four days, four sailors are dead, and the war on shipping has reached NATO's own economic zones.

At around 3 a.m. on Tuesday, October 6, some 70 nautical miles east of the Bulgarian town of Byala, drones found two merchant ships in the dark. The Alfa Watan, a Togo-flagged cargo vessel sailing from Egypt toward the Danube port of Sulina, took critical structural damage and went down; a ferry diverted to the scene found an overturned lifeboat and life jackets, and the search for her crew is still running.

The second ship, the Palau-flagged Able, loaded with wheat and bound for Istanbul, caught fire; all 18 sailors, 11 Turkish and 7 Indian citizens, came off alive, two hospitalized in Varna. Both vessels are Turkish-owned per the Equasis database cited by Turkish Minute, and both were hit inside Bulgaria's exclusive economic zone, untouched until Tuesday in this war.

Black Sea Ship Attacks: Nine Merchant Vessels in Four Days

This week's Black Sea ship attacks cap the most violent stretch for civilian shipping of the full-scale war. On Saturday, October 3, a Russian strike on a Liberian-flagged cargo ship in the Odesa region killed one crew member and injured three, per the Kyiv Independent. Over the weekend, Splash247 reported four more dry cargo vessels hit at Chornomorsk, Vylkove and the Bug estuary, which Russia's defense ministry claimed carried military cargo, offering no evidence.

Monday brought the Royad Mammadov, sunk in Romania's exclusive economic zone with two of her 13 crew dead. On Tuesday, a Marshall Islands-flagged vessel carrying rapeseed oil was also hit by a Russian drone nearer the Ukrainian coast, killing one crew member and wounding seven, per Odesa Oblast Governor Oleh Kiper. That is at least nine merchant vessels in four days by our count, four sailors killed, more missing.

The pattern is not new, only the tempo. On September 23 a Russian drone killed the captain of a ship leaving a Ukrainian port; the Maritime Guard pulled the other 15 crew off the burning vessel. Ukraine counts 274 civilian vessels and more than 1,100 port facilities damaged since February 2022, per Splash247.

The Royad Mammadov: Sunk Nine Miles From a Gas Platform

The Royad Mammadov, a 6,933-deadweight-ton bulk carrier built in 2006 and Turkish-owned per Euronews, loaded Ukrainian corn at the Danube port of Izmail, bound for Ravenna, Italy. Per Euronews and the Kyiv Independent, she was hit about 20 nautical miles off the Romanian coast, roughly 9 from the Pescarus gas platform, and sank after catching fire.

President Volodymyr Zelensky said two Russian drones struck the vessel, which he said belonged to Türkiye and was carrying corn in neutral waters. The captain was among the two dead; 11 sailors, citizens of Azerbaijan and India, were rescued. "Russia consistently chooses terror and sinking civilian ships instead of normal navigation," he wrote.

"It is a commercial ship, a ship that is not part of the war... it is not their war," Adrian Mihalcioiu, head of Romania's seafarers' union, said, as quoted by Euromaidan Press.

Bulgaria's First: An Attack Inside a NATO Economic Zone

Sofia woke to an emergency cabinet meeting. Prime Minister Rumen Radev called the strikes "absolutely unacceptable", a flagrant violation of maritime law, and said, per AP, that this was the first attack on shipping in Bulgaria's economic zone. Defence Minister Dimitar Stoyanov sent two helicopters and a Su-25 to sweep the area.

Neither Sofia nor Bucharest has named the attacker. The origin of the drones is still being established, Radev said, even as Bulgarian media cited sources pointing at Russia, per Euromaidan Press. Romania initially called Monday's sinking a fire on board. The caution has a logic: an economic zone is not national territory, and treating an attack there as one forces choices both capitals prefer to avoid. But the longer the ambiguity holds, the cheaper the next strike becomes.

Why Russia Is Hunting the Grain Fleet

The cargoes tell the story: corn out of Izmail, wheat off the Danube, rapeseed oil off the Ukrainian coast. The Black Sea route carries about 90 percent of Ukraine's agricultural exports, by Kyiv's assessment cited by Euromaidan Press. Sinking the ships that carry them prices Ukrainian trade out of the insurance market; Radev himself warned of rising insurance costs.

Moscow told everyone this was coming. After Ukrainian naval drones crippled the tankers Virat and Kairos last December, Putin called the attacks piracy and threatened to strike ships of countries helping Ukraine, up to the "most radical option", cutting Ukraine off from the sea, in remarks carried by Russian state media. It fits the winter template: Ukrainian intelligence says captured documents show Putin ordering broader strikes on civilian targets before winter. A grain ship is a civilian target that cannot shoot back.

Türkiye is caught between both campaigns. In August two Turkish-owned ships were hit by drones after leaving Russia's Novorossiysk, and Ankara later summoned Ukraine's ambassador; its foreign ministry warned then of "multidimensional adverse consequences, including for food security." Now Turkish crews are being pulled from the water on NATO's side of the sea.

Ukraine's answer at sea has been its drone fleet: September's first naval drone battle and the blockade campaign against Russia's shadow fleet. None of that protects a corn carrier 70 miles off Bulgaria. Escorts or NATO patrols might, and that is the decision this week puts on the table.

Why It Matters

This week's dead and missing are Azerbaijani, Indian and Turkish sailors under Togo, Palau and Marshall Islands flags: the neutral world that keeps Ukraine's trade alive. If drones can sink ships in NATO economic zones without consequence, the war-risk calculus changes for every shipowner in the corridor, and Russia gets what quitting the grain deal in 2023 could not deliver: Ukrainian grain priced toward uninsurable. Economic zones are where most of the world's shipping lives; the precedent reaches far past Ukraine.

What to Watch

Bulgaria's investigation, and whether Sofia names Russia. Any move toward NATO consultations. War-risk premiums, and whether corridor traffic pauses. Whether Türkiye moves beyond statements. And the next overnight tape, because nine ships in four days reads less like a warning than a policy.
