A fire broke out at a drone production facility in Skarżysko-Kamienna, Poland, at the WB Electronics plant, which is the largest drone producer in the EU and supplies Ukrainian and Polish armed forces. Polish Prime Minister Donald Tusk stated with certainty that the fire was deliberate arson, likely ordered by Russia as an act of sabotage. Earlier, a fire also occurred at a JFG Composites aerospace production facility in Lublin, Poland, but evidence of sabotage there is not confirmed. Polish prosecutors and security services are investigating the Skarżysko-Kamienna fire as a potential terrorist act involving foreign intelligence. Surveillance footage captured a masked individual entering the WB Electronics plant. The incidents come amid increased Russian sabotage and terror activities in Poland and Germany, including attacks on German electric substations and a drone attack on Leipzig airport attributed to Russia. Interior Minister Marcin Kierwiński warned of a potential escalation in Russian sabotage. A 2026 report identified Poland as a primary focus of Russian sabotage efforts. There are ongoing efforts to detain suspects involved in previous sabotage events linked to Russia.
