Polish Prime Minister Donald Tusk has identified two Ukrainian citizens, allegedly working for Russian intelligence, as the perpetrators behind two recent acts of sabotage on Poland’s rail network. The incidents, which occurred near the villages of Mika and Pulawy, involved the detonation of a military-grade C4 explosive and damage to railway infrastructure, respectively. Tusk described these acts as ‘unprecedented sabotage’ aimed at causing rail catastrophes and sowing panic in Polish society. The suspects, one residing in Belarus and the other in eastern Ukraine, had crossed into Poland from Belarus and later returned there. Tusk emphasized that Russia’s motivation was not only to disrupt railway operations but also to stir anti-Ukrainian sentiment among Poland’s large Ukrainian refugee population. Poland, a NATO and EU member, has been a critical transit route for aid to Ukraine since Russia’s full-scale invasion in February 2022. In response to the incidents, Tusk announced plans to raise the alert level on certain railway lines and highlighted that 55 individuals have been detained since last year for suspected involvement in sabotage activities. Russia has yet to comment on the allegations.
