Poland probes suspected foreign sabotage after arson at drone factory supplying Ukraine

Polish prosecutors have launched a terrorism investigation into a fire at a drone factory in Skarżysko-Kamienna, suspecting arson involving foreign intelligence services. The blaze broke out in the early hours of Monday at a plant operated by WB Electronics, one of Poland’s largest private defense companies, which produces reconnaissance drones and loitering munitions, including the FlyEye and Warmate models used by Ukraine against Russian forces.
In a statement, prosecutors said the fire was deliberately set using a device containing flammable materials and that the probe targets “participation in the activities of a foreign intelligence service against the Republic of Poland and the commission of a terrorist offense.” The damage is estimated at at least 15 million PLN, with warehouse facilities destroyed, according to the prosecution .
Security camera footage reportedly captured an unidentified person in a balaclava entering the premises after climbing a fence, leaving behind a backpack and a sweatshirt near the site. Firefighters contained the blaze in under two hours, and no injuries were reported. Police and the Internal Security Agency secured the scene for a detailed investigation, with a fire expert assisting on-site .
WB Electronics, headquartered in Skarżysko-Kamienna, approximately 140 kilometers south of Warsaw, manufactures components for unmanned systems supplied to the Polish and Ukrainian militaries. Remigiusz Wilk of WB Group told TVN24 that the company is a major entity in Poland’s security system, cooperating with thousands of enterprises, and that production would resume once authorities completed their work .
The investigation comes amid heightened concerns in Europe over suspected Russian sabotage operations. Polish Prime Minister Donald Tusk said in August that a Russian citizen had been detained in Warsaw on suspicion of being recruited by Russian services for an assassination plot. Other NATO members have reported similar hybrid threats, with incidents such as an unexploded drone discovered at a German airport earlier in August .
