Warsaw believes two Ukrainians with links to Russia were behind the “unprecedented act(s) of sabotage” on a Polish railway line leading to the Ukrainian border.
Prime Minister Donald Tusk previously said that those responsible for the blasts would be caught following an investigation, “regardless of who their backers are.”
Wysadzenie toru kolejowego na trasie Warszawa-Lublin to bezprecedensowy akt dywersji wymierzony w bezpieczeństwo państwa polskiego i jego obywateli. Trwa śledztwo. Tak jak w poprzednich tego typu przypadkach, dopadniemy sprawców, niezależnie od tego, kto jest ich mocodawcą.

Then, addressing Parliament on Tuesday, he said that one of the suspected perpetrators was believed to be a Ukrainian citizen who was convicted for “acts of sabotage” by a court in Lviv earlier this year, and that the other is a resident of the Russian-occupied region of Donbas. Both are understood to have crossed into Poland from Belarus this autumn—yet another illustration of Europe’s leaky borders.
Tusk told officials that the suspects “have been operating and cooperating with Russian services for a long time.”
Polish Defence Minister Władysław Kosiniak-Kamysz also announced on Monday that security efforts are being boosted along the railway line following the attacks.
Particular attention will be paid to critical infrastructure elements: bridges, viaducts, tunnels, stations, turnouts and railway traffic control devices.
The Territorial Defense Forces will use unmanned aerial vehicles during patrols, and starting tomorrow, the operation will be supported by a helicopter.
Zwiększamy zaangażowanie @terytorialsi 🤝 we wsparciu Straży Ochrony Kolei w patrolowaniu linii kolejowych we wschodniej Polsce. Szczególna uwaga zostanie zwrócona na newralgiczne elementy infrastruktury: mosty, wiadukty, tunele, stacje, rozjazdy czy kolejowe urządzenia… pic.twitter.com/PyVAjcXk0C

Kremlin spokesman Dmitry Peskov said Tusk’s speech on the two suspects demonstrated Warsaw’s “Russophobia,” jibing: “It would be strange if Russia wasn’t blamed straight away.”
Their identities are known to Polish authorities but are yet to be released pending further investigation. This could be as soon as later on Tuesday.
