Ukrainian drones have increasingly breached the airspace of NATO and European Union member states in the Baltics, raising serious questions about the alliance's eastern flank air defences.
Recent months have seen drones crash into an Estonian power plant chimney, strike empty fuel tanks in Latvia, and be intercepted by Romanian fighter jets over Lithuania. This culminated in residents of Vilnius, Lithuania, seeking shelter in underground car parks on Wednesday following warnings of unidentified drone activity originating from neighbouring Belarus.
