On Friday, rescuers continued their search for seven sailors missing from the San Marino-flagged chemical tanker Wine Trader, which had been struck by a drone early Thursday, approximately a mile outside Romanian territorial waters. Five crew members from the Wine Trader were rescued, some requiring treatment for burn injuries and smoke inhalation. Another incident occurred late Wednesday, when the Comoros-flagged chemical and oil tanker Yara J was hit inside Romanian waters. Its crew remained unharmed, and the ship was subsequently towed to Constanta. These two strikes contributed to a broader pattern of drone attacks on at least seven cargo vessels in the Black Sea this month, off the coasts of NATO members Romania and Bulgaria. The cumulative toll from these incidents included two people dead and at least 25 still missing.
Romanian President Nicusor Dan stated on Thursday that "two drones" had struck the vessels. While he did not specify their origin, he warned of a "reaction from the Romanian state." A NATO military source later attributed the drones to Russia. Romania's acting Foreign Minister Oana Țoiu stated that Romania holds Russia fully responsible for this latest wave of strikes.
The attacks near Romania followed earlier strikes in Bulgaria's exclusive economic zone and adjacent waters. On Tuesday, two ships sank in these areas. One of the vessels, the Dignity, a Guinea-Bissau-flagged cargo ship, sank after being hit by a military strike. Four sailors, three Syrian nationals and one Egyptian, were rescued and arrived in the port of Varna, according to district Governor Mario Smarkov. A fifth sailor was expected to arrive later on Wednesday. The search for 11 missing crew members from these Tuesday incidents continued, adding to the total number of individuals unaccounted for across the region. The other vessel struck on Tuesday, the Chelsea-3, was Ukrainian-owned, registered in Odesa, and sailed under the flag of Malta.
Bulgaria stated on Wednesday that Russia was likely behind the drone attacks that had struck four vessels over the past week, though it noted the absence of definitive proof of Moscow's culpability. Bulgarian Prime Minister Rumen Radev told Parliament that "there is no logic in Ukraine attacking its own ships and crews," given that the outcome of all these attacks favored Russia. Radev summoned the Russian ambassador to Sofia on Tuesday. The ambassador stated she did not have information from the Russian defense ministry, but she did not rule out the possibility that these attacks represented "a provocation by a third party," suggesting an alternative explanation for the incidents.
In response to the incidents, Bulgaria requested international assistance for the investigation into attacks on commercial vessels. It also sought NATO support to strengthen surveillance and control systems against drone attacks, formally asking for combat aircraft, air defense systems, counter-drone equipment, and air patrols to bolster its defenses. Defense Minister Dimitar Stoyanov stated on Wednesday that Bulgaria expects to join a NATO anti-drone initiative by October 30.
The cumulative effect of these strikes has drawn attention to the security of global shipping routes in the Black Sea, particularly for the transport of vital commodities. Ukrainian Foreign Minister Andrii Sybiha stated that the Black Sea could become a "second Strait of Hormuz" for global food security due to Russia's blockade, highlighting the potential for broader economic disruption. The attacks this month, targeting at least seven vessels, add to a pattern observed earlier in the year. During the first eight months of this year, at least 163 civilian and commercial vessels were hit in the Black Sea, establishing a precedent for the current wave of incidents.
