The ministry said 25 Azerbaijani nationals were among the crews of the vessels struck in Taganrog Bay, adding that neither ship belonged to Azerbaijan.

Earlier, Ukraine said its drones had hit five vessels in the ports of Mariupol and Berdyansk and in nearby coastal waters under Russian control.

Robert Brovdi, commander of Ukraine’s drone forces, said the targeted ships included dry cargo vessels and a tanker allegedly involved in transporting military cargo, fuel and Ukrainian grain.

The attacks mark one of the deadliest incidents involving foreign civilian crew members in the conflict’s maritime zone this year.

Yuri Slyusar, governor of the Rostov Oblast, said falling drone debris triggered fires and prompted evacuations in affected areas.

“Emergency crews are working at the site of the incident, where the debris fell,” he said on Telegram, adding that damage had been recorded and residents moved to safety.

Taganrog Mayor Svetlana Kambulova said emergency services responded to 49 incidents across the city. Eight people were reported injured.

She said debris from intercepted drones damaged multiple residential buildings, social infrastructure and industrial facilities. Emergency crews remained deployed, while air defense units continued operations in the area.

Taganrog, a port city on the eastern edge of the Sea of Azov, lies close to the Ukrainian border and has periodically been affected by spillover from the conflict.

There was no immediate comment from Ukrainian authorities on the reported strike.
