Romania scrambled F-16 fighter jets on Aug. 20 to destroy an explosive-laden marine drone a few hundred meters from its Neptun Deep natural gas project in the Black Sea, Defense Minister Radu Miruta revealed in a Facebook post the same day. Miruta did not attribute the drone but said Ukraine denied ownership, while President Nicusor Dan blamed Russia, and European Commission President Ursula von der Leyen called the incident "hybrid warfare" and an " escalating campaign of threats ."
