Overview
- Romanian authorities say a seadrone detonated in the civilian area of Constanța port on Friday, June 5, 2026, after intelligence, the coast guard and defence forces had secured the device and were attempting to neutralize it.
- Officials reported no casualties but said the explosion damaged a warehouse and a ship, with Constanța prefect Adrian Picoiu providing the details to local media.
- Kyiv has told partners the device was Ukrainian and lost control because of Russian electronic-warfare interference while Moscow rejects responsibility and accuses Romania of incomplete reporting.
- The incident follows recent regional events including a drone strike on a house in Galați that injured two people and a seadrone found near Greece for which Ukraine apologised, showing a pattern of weaponized unmanned systems landing far from their intended targets.
- European leaders have urged investment in anti-drone defences, air-defence and early-warning systems as investigations and diplomatic exchanges continue and coastal communities face increased risk from stray or misdirected drones.
