The vessel, carrying corn and owned by Turkiye, was struck by Russian drones on Monday in neutral waters near Romania. Romanian authorities confirmed two people died and 11 were rescued after the ship caught fire and sank.
Zelensky condemned the attack, saying Russia "consistently chooses terror and sinking civilian vessels instead of normal maritime navigation." He called for international pressure to restore food security in the Black Sea region.
The incident is the latest in a series of Russian strikes that have struck targets outside Ukraine, prompting European concern as the war approaches the five-year mark since Russia's full-scale invasion in February 2022. While fighting has largely been confined to Ukrainian territory, recent barrages have shown what some analysts describe as growing Russian confidence to operate in other European countries' areas.
The sinking threatens global grain shipments and further destabilises the Black Sea corridor, which Ukraine has sought to keep open for agricultural exports after Russia withdrew from the Black Sea Grain Initiative in 2023.
