Poland’s Prime Minister has officially accused Russian-backed Ukrainian separatists of attempting to derail trains on a critical supply line to Ukraine, though the sabotage efforts failed. The incident, which occurred on a main supply line, was reported to have involved two devices designed to derail passing trains. However, the devices did not succeed in their intended operation, leading to no significant damage. The two suspects involved in the sabotage are believed to have fled the country after the failed attempt.
