From Aljazeera:
A drone has exploded in Bulgaria near the Trans-Balkan gas pipeline, the latest in a surge of unidentified unmanned aerial vehicles flying into European territory as regional tensions escalate due to Russia’s ongoing war in Ukraine.
Bulgarian Prime Minister Rumen Radev said on Saturday that the drone exploded near the Romanian border and the gas pipeline, which links Turkiye to Ukraine. Bulgaria’s Ministry of Defence said an initial analysis indicated that the aircraft was most likely a Maya decoy drone, a type widely used by the Ukrainian armed forces. The ministry said there was no reason to suspect the incident was intentional.
