Drone explodes near Bulgarian gas pipeline, Sofia summons Ukrainian ambassador

Drone explosion near gas pipeline

A drone entered Bulgarian airspace from Romania on Saturday, August 8, and exploded in a sunflower field near the Kardam border crossing, approximately 100 meters inside Bulgarian territory. The blast occurred about 1,000 meters from a Bulgarian compression station of the Trans-Balkan gas pipeline, which runs from Turkey to Ukraine, and 200 meters from a corresponding Romanian compression station. No casualties or infrastructure damage were reported. Bulgarian President Rumen Radev confirmed the area had been secured and said the government continued monitoring the situation.

The exact time of the incident varies between sources: some cite shortly after 5 AM local time, while others report 8:10 AM local time. The drone was not detected by either Bulgarian or Romanian radar systems during its flight, a fact Radev said confirms that timely detection and identification of drones remains a challenge. He also noted delays in the delivery of high-precision radar to the Bulgarian military and pledged action.

Bulgarian investigation and Ukrainian response

Bulgaria's Defense Ministry announced that debris analysis indicated the drone was most likely a Maya-type decoy drone, widely used by the Ukrainian armed forces. The ministry stated there was no reason to consider the incident deliberate. Defense Minister Dimitar Stoyanov said the drone appeared to have carried a significant quantity of explosives, given the power of the blast and the column of black smoke, though the Defense Ministry also noted this drone type is not designed to carry explosives.

Bulgaria's Foreign Minister Velislava Petrova will summon Ukraine's ambassador Olesia Ilashchuk for explanations on Monday. Ukraine's Foreign Ministry spokesperson Heorhii Tykhyi denied any deliberate targeting.

“We can state with certainty that the Ukrainian army did not deliberately direct any aircraft toward Bulgaria.”

Tykhyi did not officially confirm the drone was Ukrainian but said Ukraine would investigate the incident.

Security measures and NATO consultation

Radev announced enhanced security around strategic installations and increased surveillance along the Bulgaria-Romania border. He said drone detection and countermeasure capabilities from the border police would be transferred from the Turkey border to the Romania border. The incident will be raised at a North Atlantic Council meeting early next week, according to Defense Minister Stoyanov.

Regional context of drone incidents

The incident occurs amid a rise in drone-related events in the Black Sea region linked to the Russia-Ukraine war. Romania has experienced increased airspace violations in recent months. In late May, a drone carrying explosives crashed into an apartment building in Romania, injuring two people. In late July, Romanian forces shot down three drones in three days, with at least one identified as a "Shahed" type used by Russian forces. Former Bulgarian Defense Minister Todor Tagarev told AFP that Bulgaria, a NATO member like neighboring Romania, had "never had an incident of this type with a drone with explosives." Opposition MP Ivaylo Mirchev noted that Kardam is part of the "Vertical Gas Corridor," a strategic route for transporting liquefied natural gas from Greece to Southeast and Central Europe, connecting Greece, Bulgaria, Romania, Hungary, Slovakia, Moldova, and Ukraine.
