A spokesperson for Poland’s special services minister accused Russian intelligence Tuesday of orchestrating a railway blast that destroyed a key track on a route used to deliver aid to Ukraine. Jacek Dobrzyński told reporters that "everything indicates" Russian intelligence was behind the sabotage of Polish railways.

A railway line bringing passenger trains into Warsaw from southeastern Poland on Sunday was sabotage, the prime minister said. Prime Minister Donald Tusk said Monday the damage to the line between Warsaw and Lublin on Sunday was caused by an explosion.
