Poland is raising the alarm after a blast struck a key railway line used to send aid and military supplies into Ukraine, calling the incident an unprecedented and deliberate act of sabotage. The explosion happened over the weekend on a stretch of track between Warsaw and southeastern Poland, near the village of Mika — a crucial corridor for moving equipment and humanitarian support toward Ukraine. A second section farther south was also damaged, where overhead power lines were cut in what authorities believe was a coordinated attempt to disrupt rail traffic.
Prime Minister Donald Tusk and top security officials say the evidence strongly points to Russian involvement. According to Poland’s Security Services Minister, Tomasz Siemoniak, the operation carried the hallmarks of foreign intelligence work, describing it as “highly likely” to have been ordered from abroad and executed with professional skill. Prosecutors have opened a terrorism-related investigation tied to actions taken on behalf of a foreign intelligence service.
Tusk revealed that two Ukrainian nationals are suspected of working with Russian secret services to carry out the sabotage. Their identities are known to authorities but are not being released publicly at this stage. Poland’s Defence Minister added that military patrols and investigators are now securing the rail corridors and reviewing camera footage recovered near the damaged tracks.
The targeted line is one of the main arteries for transporting weapons and humanitarian aid from Poland into Ukraine. While passenger services were halted, no injuries were reported. Polish officials view the attack as a clear example of Russia’s hybrid warfare strategy — an effort to disrupt European support for Ukraine, sow fear, and blur the boundary between wartime aggression and covert operations.
The incident comes amid a series of suspected sabotage attempts across Europe linked to Russian intelligence networks. As a key conduit for aid flowing into Ukraine, Poland sees the attack as both a warning and an escalation. Warsaw has vowed to tighten protection of critical infrastructure and act decisively against any attempts to undermine its security.
In short, Poland believes the railway blast was a calculated act of professional sabotage tied to Russian secret services, carried out by Ukrainian collaborators working on Moscow’s behalf, and aimed at obstructing the flow of aid to Ukraine as part of a broader campaign of destabilization across Europe.
