EU and NATO leaders are currently pointing the finger at Russia for what could be one of the single biggest acts of sabotage on European soil since the Ukraine war began.

A train track linking the Polish cities of Warsaw and Lublin was destroyed in an "unprecedented act of sabotage" on Sunday. Polish Prime Minister Donald Tusk declared that the now damaged railway is "crucially important for delivering aid to Ukraine." In invoking Ukraine aid, he's clearly letting suspicion fall on Moscow - though no arrests have been made in the early investigation. But photos suggest it's only a very small section of track left missing and subject to damage. And yet this could indeed be enough to derail a train.

An "explosive device" blew up the rail track, Tusk stated X. He followed by decrying that the act "directly (targeted) the security of the Polish state and its civilians." Apparently there was more damage even beyond this, with destruction located further down the line as well.

"Unfortunately, the worst suspicions were confirmed. An act of sabotage occurred on the Warsaw-Lublin line (in the village of Mika). An explosive device detonated and destroyed the railway track," Tusk said.

While not directly naming Russia, European Commission President Ursula von der Leyen was quick to chime in, calling for greater European collective defense, also to 'protect the skies' amid alleged Russian-directed drone operations...

Estonia's Prime Minister Kristen Michal additionally condemned the apparent sabotage op, writing on X that he and his country stand with Poland. "Those behind hostile acts against (European Union) and NATO members must be exposed. Our response must be united," Michal said.

Estonia is one among several Balkan and Eastern European countries which have lately been alleging EU airspace is being widely sabotaged by Russian drones or at times military aircraft incursions.

As for the location of the alleged train track sabotage, Mika is located a little over 60 miles from Warsaw. It could indeed be part of an ongoing tit-for-tat sabotaging of both Russian and European infrastructure, in a long-running chain of mystery events.
