On Thursday morning a San Marino‑flagged chemical tanker, the Wine Trader, was struck by drones off the Romanian Black Sea coast. The vessel caught fire about 13 nautical miles east of the Danube’s mouth at Sulina, and seven of its twelve crew members have not been located.

What happened

According to Romanian naval authorities, the Wine Trader reported a series of explosions and a fire at roughly 07:00 local time (05:00 GMT). Witnesses on nearby ships said the tanker was hit by two unmanned aerial systems. The incident follows a similar drone strike on another chemical tanker, the Yara J, the day before.

Rescue effort

Romanian officials have deployed two Black Hawk helicopters and two rescue boats to the scene. The interior ministry released video footage of a helicopter hovering above the burning vessel. The priority is to locate the four crew members confirmed alive while ensuring the safety of rescue teams amid very high waves.

Regional security context

The attacks come amid a broader pattern of drone strikes on merchant ships in the Black Sea. Earlier in the week, two merchant vessels were hit off Bulgaria’s coast, one of which sank, leaving eleven crew members missing. Romania and Bulgaria’s leaders are scheduled to meet NATO Secretary‑General Mark Rutte in Brussels to discuss whether to invoke Article 4 of the NATO treaty, which allows members to request consultations when territorial integrity or security is threatened.

Competing narratives

Romanian President Nicușor Dan confirmed that both the Wine Trader and the Yara J were hit by drones. Moscow, however, claimed that two cargo ships carrying military supplies to Ukraine’s Odesa port were targeted, without naming the vessels. Ukraine and its European allies accuse Russia of deliberately attacking civilian merchant vessels, while Russia blames Ukraine for strikes on Russian‑flagged ships.

Implications for shipping

The Black Sea remains a critical corridor for Ukrainian exports and imports, especially grain. The recent spate of attacks has prompted calls from Turkey and the European Commission for a cease‑fire, but Moscow has rejected such proposals, insisting it is targeting ships it deems to be delivering weapons to Ukraine.

Uncertainty

While the immediate focus is on rescuing the missing crew, several uncertainties remain:

Looking ahead

As the search continues, the incident underscores the escalating risk to commercial shipping in the Black Sea. The outcome of the upcoming NATO discussions could shape the alliance’s posture in the region and influence future maritime security protocols.
