Polish Prime Minister Donald Tusk has labeled an explosion on a railway line near Warsaw as an ‘unprecedented act of sabotage,’ vowing to bring the perpetrators to justice regardless of their affiliations. The incident, which occurred on Sunday, targeted a critical supply route to Ukraine, raising concerns over the security of Poland’s railway infrastructure. Tusk, who visited the site, confirmed the damage was deliberate and likely intended to derail a train, though no casualties were reported. Poland’s Special Services Minister, Tomasz Siemoniak, suggested a ‘very high chance’ that foreign intelligence services orchestrated the attack, hinting at Russia’s involvement without explicit naming. This incident follows a series of suspected hybrid warfare tactics attributed to Moscow, including parcel bombings and arson attacks. Investigators are also probing a second suspicious event on the same railway line, where a packed train was forced to halt abruptly, believed to be another act of sabotage. The explosion near Mika, approximately 100km southeast of Warsaw, was detected early Sunday morning, with photographs revealing a missing section of track. Despite the damage, no injuries were reported among the few passengers and staff on board. Poland’s Interior Minister confirmed the use of explosives, though details remain undisclosed due to the ongoing investigation. Local residents reported hearing a significant blast the previous evening, initially mistaking it for a gas explosion or falling drone. Authorities have collected substantial evidence, including security camera footage, to identify those responsible. This attack marks the first direct assault on Poland’s railway network, which serves as a vital military supply line to Ukraine. Experts speculate the sabotage aimed to psychologically intimidate Poland into reducing its support for Ukraine. Polish officials have pledged to prosecute those involved ‘ruthlessly,’ emphasizing that there is ‘no place on earth they can hide.’ However, the government faced criticism over the delayed detection of the damage and the possibility of such sabotage occurring. Officials defended their response as swift and effective, dismissing criticism as ‘untrue and insulting.’ This incident underscores the escalating tensions in the region and the vulnerabilities of critical infrastructure in the face of hybrid warfare tactics.
