Drones spotted in Bulgaria and Germany raise concerns of Russian Escalation
A drone exploded near Bulgaria’s border with Romania and a key gas pipeline, while Germany reported new drone sightings at a military base and Leipzig/Halle Airport, intensifying fears that the Russia-Ukraine war could increasingly affect NATO territory.
The Bulgarian drone crashed in a sunflower field near the Kardam border crossing on Saturday, about one kilometre from a compressor station serving the Trans-Balkan gas pipeline, which connects Türkiye and Ukraine. No casualties or infrastructure damage were reported.
Bulgaria’s Defence Ministry said an initial assessment suggested the aircraft was most likely a Maya decoy drone, a type widely used by the Ukrainian armed forces. Officials said there was no indication that the incident was intentional. Ukraine also denied deliberately directing any military assets toward Bulgarian territory and said it was cooperating with Bulgarian authorities to clarify what happened.
The incident nevertheless prompted a diplomatic response. Bulgaria summoned the Ukrainian ambassador, while Prime Minister Rumen Radev announced stronger surveillance along the border and plans to redeploy troops equipped with counter-drone capabilities. Authorities said neither Bulgaria nor neighbouring Romania detected the aircraft before it exploded.
Germany has also reported several drone incidents this week. Two drones were spotted around 10 p.m. on Thursday near a Bundeswehr military site in Mechernich, North Rhine-Westphalia. The location reportedly contains a secure underground facility and supports personnel responsible for maintaining US Patriot air-defence systems. German police are investigating the sightings.
Another drone was discovered earlier at Leipzig/Halle Airport, a major civilian freight and NATO logistics hub, close to Ukrainian Antonov An-124 cargo aircraft. German authorities have not publicly blamed any foreign government for the incidents, although some politicians have pointed to Russia and its previous alleged hybrid activities in Europe.
The latest incidents have renewed concerns about NATO's ability to protect critical infrastructure from increasingly sophisticated drone threats. NATO and EU officials have previously accused Russia of dangerous drone activity, while Moscow has rejected such allegations. Russia's embassy in Berlin dismissed the Leipzig incident as a “fabricated provocation” and said accusations against Moscow were unsupported by evidence.
