Poland investigates arson at WB Electronics drone factory as act of sabotage
Polish authorities launched terrorism and espionage probes after an intruder ignited a fire at WB Electronics in Skarzysko-Kamienna, following a separate blaze at a military supplier in Lublin.
Arson at WB Electronics
Polish prosecutors opened a formal investigation into suspected terrorism and activities on behalf of a foreign intelligence service following a fire at the WB Electronics plant in Skarzysko-Kamienna, roughly 150 kilometres south of Warsaw. The fire broke out on the morning of Monday, 31 August 2026, and emergency crews extinguished the flames quickly, preventing any casualties. Security camera footage obtained by investigators showed an intruder wearing a balaclava and carrying a backpack, who ignited a fire inside a production area before triggering the facility's alarm system. WB Electronics operates as Poland's largest private defence manufacturer, supplying hardware to the Polish military while manufacturing FlyEye reconnaissance drones and Warmate loitering munitions used by Ukrainian armed forces.
Government attribution and regional threats
Speaking after a cabinet meeting in Warsaw on Wednesday, 2 September 2026, Prime Minister Donald Tusk identified the fire as an act of deliberate sabotage. Tusk stated that Eastern European nations face critical security challenges in the coming weeks and months, connecting the factory arson to broader destabilisation efforts across the region, including foiled attacks at Leipzig airport that German authorities attributed to Moscow. Polish Deputy Interior Minister Czeslaw Mroczek stated on Tuesday that European security services have tracked sabotage operations across countries supporting Ukraine for several years.
This is a continuation of Russia's escalatory actions throughout the region.
The Polish government also referenced domestic counter-intelligence actions in August 2026, when authorities in Warsaw detained a Russian citizen accused of planning the assassination of a Ukrainian-American national, as well as a Ukrainian national.
Parallel fire and cryptocurrency disputes
The Skarzysko-Kamienna incident occurred hours after a separate fire on Sunday, 30 August 2026, damaged a production hall at JFG Composites near Lublin in south-eastern Poland. JFG Composites manufactures specialised aeronautical components for the Polish armed forces. Tusk noted that while investigators currently lack conclusive evidence linking the Lublin fire to external sabotage, the possibility remains under active review due to the facility's military supply role.

- Prime Minister Donald Tusk calls the drone factory fire deliberate arson
- Parliament scheduled to vote on overriding presidential veto of cryptocurrency bill
To combat covert operations, Tusk stated an intention to tighten domestic cryptocurrency regulations, asserting that foreign intelligence networks utilise digital assets to finance saboteurs on Polish soil. The draft legislation has faced institutional opposition from Polish President Karol Nawrocki, who has vetoed the regulatory bill three times. Lawmakers in parliament are scheduled to vote on Friday, 4 September 2026, on whether to overturn the presidential veto. As a member of both the European Union and NATO, Poland functions as the central logistical hub through which international military and humanitarian shipments reach Ukraine.
