Explosions at a Bulgarian Arms Depot: What Investigators Are Checking
Bulgarian authorities are investigating an overnight fire that set off explosions at an ammunition storage site run by private defence company EMCO in central Bulgaria. No one was injured. The blaze was reported on September 12, 2026. BBC
The site is near the village of Gorni Varpishta, about 170km east of Sofia. Smoke and fire from the warehouse were also reported near the village of Tsareva Livada. Interior Minister Ivan Demerdzhiev said authorities are not ruling out outside interference. BBC
EMCO blamed sabotage, a deliberate act to damage or disrupt. The company said human error was completely ruled out. It said the building had not been used for months and had been inspected 20 days earlier, with full compliance confirmed.
The incident follows a fire and blasts last month at another EMCO ammunition warehouse in the same area. EMCO representatives described the September 2026 explosion as sabotage, as with the previous incident.
EMCO is run by Bulgarian arms dealer Emilian Gebrev. Bulgarian prosecutors allege Gebrev was targeted by Russian agents, including a 2015 poisoning attempt on Gebrev, his son and another employee for which three Russian nationals were later charged in absentia with attempted murder. BBC

The broader context here is the gap between a sabotage claim and formal proof of who was behind it. An unused store inspected weeks before the fire narrows some routine explanations for an accident. It does not by itself establish method, access or actor. Investigators will need to reconstruct the ignition sequence, check perimeter security logs and personnel access, and examine any recovered initiators or residues before the outside-interference hypothesis can be tested. Two EMCO warehouses burning in the same district within about a month sharpens that task. It raises related questions about protection of dispersed stockpiles, custody during idle periods, and whether the incidents share a signature.
Looking at what this means for Sofia, political handling of the case matters alongside the technical findings. An allegation involving a defence exporter whose weapons are in use in Ukraine carries diplomatic and counterintelligence weight. Bulgarian prosecutors have already placed Gebrev in a prior narrative of Russian targeting, which will shape how outside observers read Demerdzhiev's statement. The details to watch are what forensic material the Interior Ministry releases, whether prosecutors open a parallel pre-trial proceeding on sabotage or terrorism-related statutes, and what protective measures are ordered for other storage nodes. Until then, the positions are an official investigation with outside interference not excluded, and a company assertion of deliberate sabotage.
