Poland’s prime minister, Donald Tusk, has described an explosion along a section of railway line used for deliveries to Ukraine as an “unprecedented act of sabotage” that could have led to disaster.

There were no casualties from the incident on the line from Warsaw to Lublin, but the consequences could have been catastrophic if the gap in the tracks had caused a train travelling at full speed to derail.

“Unfortunately, there is no doubt that we are dealing with an act of sabotage. Fortunately, there was no tragedy, but the matter is nonetheless very serious,” Tusk said on Monday, after visiting the scene 60 miles (97km) from Warsaw, near the village of Mika.
