Poland Investigates Suspected Sabotage at Drone Factory

Poland has opened a terrorism and foreign-intelligence investigation after a fire broke out at a WB Electronics factory in Skarżysko-Kamienna, south of Warsaw. The facility produces important drone components and military technology used by both the Polish and Ukrainian armed forces. The fire reportedly began shortly after midnight, and firefighters took about two hours to contain it. The Polish National Prosecution Office said the investigation concerns alleged participation in the activities of a foreign intelligence service directed against Poland, as well as a terrorist offence involving the deliberate ignition of a fire with a device containing flammable materials. Authorities have not released further details, citing the confidential nature of the investigation. Poland’s Internal Security Agency is assisting police. The article places the incident within a broader European security context. Russia is widely suspected of conducting sabotage operations against facilities and infrastructure supporting Ukraine’s war effort, although the article does not report that Russian involvement has been established in this case. Several European countries have reported incidents believed to be linked to such operations. Polish Prime Minister Donald Tusk recently said a Russian citizen had been detained for allegedly being recruited by Russian services to carry out an assassination in Warsaw. Separately, an unexploded drone was found at a German airport. WB Electronics is one of Poland’s largest private defence companies. It produces drones, loitering munitions, fire-control systems and military communications equipment. Ukrainian forces use the company’s FlyEye and Warmate drones. Poland has increased defence spending and strengthened its military and security capabilities because of concerns about possible Russian attacks, making the factory a strategically significant site.

Polish authorities have launched an investigation into a fire at a drone-production facility in Skarzysko-Kamienna, about 150 kilometers south of Warsaw. Prosecutors suspect that the blaze may have been deliberately started using a device containing flammable materials and are investigating possible participation in the activities of a foreign intelligence service as well as a terrorist offense. The fire broke out shortly after midnight on Monday at a factory operated by WB Electronics, a major Polish defense company that manufactures key components for drones. Firefighters brought the blaze under control after approximately two hours, and no injuries were reported. Poland’s Internal Security Agency is assisting police with the inquiry. The investigation comes amid heightened Polish concerns about sabotage linked to Russia and Belarus. Polish officials have previously accused both countries of sending agents into Poland to carry out acts of sabotage, although the article does not establish that either country was responsible for this fire. Poland has strongly supported Ukraine since Russia’s full-scale invasion and has increased spending on national security and military capabilities because of concerns about possible Russian aggression. WB Electronics is described as Poland’s largest private defense company and a supplier to the Polish military. Its operations include digital command and control systems, automated fire-control systems, communications equipment, and unmanned strike systems. The incident is therefore significant not only as a suspected act of sabotage but also because it affected a company involved in Poland’s defense-industrial infrastructure.

Polish prosecutors have opened a terrorism investigation after a fire destroyed warehouse facilities at a WB Electronics drone factory in Skarżysko-Kamienna on 31 August 2026. Authorities believe the blaze was deliberately started by planting an explosive device containing flammable materials. CCTV footage reportedly showed an unidentified person wearing a balaclava entering the premises after climbing a fence, while a backpack and sweatshirt were found nearby. Prosecutors are investigating both the alleged terrorist offense and possible participation in the activities of a foreign intelligence service against Poland. The fire caused at least 15 million Polish zlotys in damage, although local firefighters described the blaze as relatively small and extinguished it in under two hours. Police secured the scene after the fire was put out, and investigators, including a fire expert, began examining the site. WB Electronics, Poland’s largest private arms company, produces reconnaissance and attack drones and components for unmanned systems used by the Polish and Ukrainian armed forces. WB Group representative Remigiusz Wilk said the factory would be able to resume production once authorities completed their work and that the incident was not expected to delay deliveries to Poland’s military. The incident was the second similar fire in Poland within 24 hours. The previous day, firefighters responded to a blaze at an aircraft-parts warehouse in Lublin. A Polish Interior Ministry spokesperson said investigators would examine any possible connection between the fires. The article also places the events in the context of reports by The Telegraph, citing Western intelligence sources, that suspected Russian sabotage operations have targeted European arms manufacturers and companies supplying weapons to Ukraine. Those operations were reportedly designed to remain below the threshold that could lead NATO to invoke its collective-defense Article 5.
