2 Ships Hit by Drones Off Bulgaria's Black Sea Coast, PM Says

Drones struck two ships off Bulgaria's Black Sea coast, Prime Minister Rumen Radev said, and one of the vessels has sunk, according to The New York Times. A rescue effort was underway as of the Times' report. It was not immediately clear where the drones originated.

What happened to the two ships off Bulgaria's coast?

Two ships came under drone fire in waters off Bulgaria, a NATO and European Union member state on the western edge of the Black Sea, the Times reported. One ship sank following the strike. Bulgarian authorities moved to recover survivors and assess the scope of the damage, Radev said, according to the Times. The paper did not report the vessels' names, flags, cargo, or crew size.

The incident adds Bulgarian waters to a stretch of the Black Sea that has seen repeated strikes on commercial and military shipping since Russia's invasion of Ukraine began. Bulgaria has largely stayed outside the direct line of fire in that conflict, making an attack in its coastal waters notable regardless of who is responsible.

Where did the drones come from?

The origin of the drones was not immediately clear, the Times reported. No government or military has publicly claimed responsibility for the strike as of the Times' report, and Bulgarian officials have not named a suspected launch point, platform, or operator.

That uncertainty is typical in early reporting on Black Sea drone and missile incidents, where attribution often takes days and can remain contested even after initial claims surface from Kyiv, Moscow, or Western intelligence agencies.

What has Bulgaria's prime minister said?

Radev confirmed the strikes and the sinking of one vessel, and said a rescue operation was in progress, according to the Times. The prime minister's office has not released additional details on casualties, the identity of the ships, or next steps beyond the search-and-rescue effort described in the initial report.

A rescue effort was underway after one of the two ships sank, Prime Minister Rumen Radev said. It was not immediately clear where the drones originated.

Is this linked to the Black Sea tanker attack Russia reported?

The Bulgaria strikes follow a separate incident in the Black Sea in which Russia said a tanker crew was rescued after an attack, according to HTT News. The two events have not been publicly linked by Bulgarian, Russian, or Ukrainian officials, and the Times' reporting on the Bulgaria strikes does not reference the tanker incident.

The Black Sea has become a recurring flashpoint for drone and missile strikes on shipping tied to the broader war in Ukraine, with vessels, ports, and grain infrastructure on both the Russian and Ukrainian coastlines targeted at various points since 2022. Whether the Bulgaria strikes fit that pattern, were a case of mistaken targeting, or involved a different actor entirely remains unanswered in the available reporting.

What happens next in the rescue effort?

The immediate priority described by Bulgarian officials is locating and recovering anyone aboard the two ships, the Times reported. No casualty figures, missing-person counts, or damage assessments were included in the initial account.

Bulgaria's government has not said whether it will request international assistance, open a formal investigation into the drones' origin, or raise the incident with NATO allies. The Times' report did not indicate whether Sofia had been in contact with Ukrainian, Russian, or Western officials since the strikes occurred.

Further details — including the identities of the ships, any casualties, and attribution for the drones — are expected as Bulgarian authorities continue the rescue operation and begin piecing together how the vessels came under fire.

Why does an attack in Bulgarian waters matter for NATO?

Bulgaria's membership in both NATO and the European Union sets this incident apart from strikes that have occurred closer to the Russian or Ukrainian coastlines. The Times' report does not state whether Sofia has invoked any alliance consultation mechanism or briefed NATO counterparts on the strikes. No alliance statement was included in the available reporting.

The absence of attribution leaves open basic questions about intent — whether the ships were deliberately targeted, caught in a wider pattern of Black Sea shipping strikes, or hit in error. Those questions are compounded by the lack of detail on the vessels themselves, including whether they were commercial, military, or flagged to Bulgaria or another state. The Times' account does not address any of those specifics, and Bulgarian officials had not filled in the gaps as of the initial report.
