Romanian authorities reported that the Comoros-flagged chemical and oil tanker Yara J, anchored in its territorial waters, caught fire and its crew was evacuated. Romanian Defence Minister Radu Miruta stated on Wednesday that an investigation is underway to determine if a drone strike was involved. This incident follows multiple drone breaches of Romanian airspace on Wednesday and comes amidst growing concerns over hybrid attacks in the Black Sea, including recent drone attacks off Bulgaria's coast that sank one ship on Tuesday and another earlier this month.
