Nov. 17 (UPI) -- An explosion damaged train tracks between Warsaw and Lublin, Poland, Sunday, and the government said it was an act of sabotage from a foreign state.

"Blowing up the rail track on the Warsaw-Lublin route is an unprecedented act of sabotage targeting directly the security of the Polish state and its civilians. This route is also crucially important for delivering aid to Ukraine. We will catch the perpetrators, whoever they are," said Prime Minister Donald Tusk on X Monday.

Poland's interior minister Marcin Kierwiński said there were two separate incidents over the weekend, CNN reported. One was deemed "highly probable" to be sabotage. No arrests have been made so far, and no injuries have been reported.

Poland has suffered a wave of attacks since the beginning of the war between Russia and Ukraine, including arson, sabotage and cyberattacks, The Independent reported. Poland blames Russia because Warsaw is a hub for aid to Kyiv. Russia has denied the attacks.
