The Russian Embassy in Bucharest claimed that the maritime drone that exploded in Romania's Port of Constanța on Friday, June 5, was of Ukrainian origin, rejecting any suggestion of Russian involvement in the incident. The statement came as Romanian authorities continued investigating the explosion, and reports emerged of additional drones drifting near Romanian territorial waters. In a statement published on Facebook, the Russian Embassy said the drone that self-detonated in Constanța Port, as well as several similar drones reportedly discovered in the Black Sea, were Ukrainian unmanned maritime vehicles.
