Polish officials say a crucial supply route used to move aid into Ukraine was likely the target of a deliberate attack over the weekend. An explosion damaged a key railway line close to the Ukrainian border, forcing a passenger train to halt unexpectedly, according to the Wall Street Journal. Prime Minister Donald Tusk condemned the blast as “an unprecedented act of sabotage,” telling the New York Times that those responsible appeared to be attempting to destroy a passing train.
On the same Warsaw-Lublin line, a separate incident involving a damaged overhead cable caused another train to stop, raising further concern about coordinated interference.
“We will catch the perpetrators, regardless of who their backers are,” Tusk vowed. While he did not directly accuse any nation, Poland has previously linked similar incidents to Russia since the start of the war in Ukraine. Poland remains one of Kyiv’s strongest supporters.
In recent high-profile events, NATO aircraft intercepted Russian drones over Polish territory—an episode seen by officials as Moscow probing the alliance’s defenses. Russia has also been blamed for drone activity that has disrupted airports across central and eastern Europe, as well as for past attacks inside Poland, including a significant fire at a major Warsaw shopping center last year. Such operations are increasingly viewed as part of Russia’s broader strategy to pressure neighboring countries without triggering a direct confrontation with NATO.
