The Chelsea 3 was hit by three drones and sustained damage about 18 nautical miles off the coast, as reported by Al Jazeera (Qatar) and the BBC (United Kingdom).
The Bulgarian government has not attributed the attacks to any specific party, but Prime Minister Radev suggested that the outcome benefits the Russian Federation, as reported by the BBC (United Kingdom) and Georgia Today (Georgia).
