Romanian authorities reported that a fire broke out on the Turkish-owned vessel, the "Royad Mammadov", around 11am local time (08:00 GMT) on Monday, leading to the deaths of two crew members and the rescue of 11 others. The ship, which was carrying corn, was located in Romania's exclusive economic zone at the time of the incident. The Romanian Ministry of Internal Affairs did not identify the cause of the fire.
Zelenskyy wrote on social media that two Russian drones struck the civilian vessel in neutral waters. According to reports, Azerbaijani and Indian nationals were among those on board.
The incident is the latest in a series of suspected incursions along NATO's eastern flank. In May, a Russian drone hit an apartment building in Romania. In June, a stray Ukrainian maritime drone exploded in the Black Sea port of Constanta. In July, Bucharest summoned Russia's ambassador after air defences intercepted three drones within a week.
