An oil pipeline in Poland has sustained two ruptures, reports Polish pipeline operator PERN, according to Reuters.

It is still unclear what caused the leaks that were discovered Tuesday evening, according to official reports.

The pipeline, known as Druzhba, consists of two separate oil pipelines. The second pipeline is functioning normally.

Druzhba, meaning ’friendship’ in Russian, is one of the largest oil pipelines in the world, transmitting oil from Russia to most of central Europe.

Recipients include Germany, Poland, Belarus, Hungary, Slovakia and Czechia.

A spokesperson for Czech pipeline operator Mero notes Tuesday that it has detected no changes in oil flows to the nation.

Approximately two weeks ago, the Nord Stream 1 and 2 gas pipelines running along the Baltic seabed suffered a series of leaks.

These leaks were later assessed to be caused by sabotage.

Swedish, Danish and German police have joined forces to uncover the exact causes of the damaged pipes.

At a press conference involving Danish Prime Minister Mette Frederiksen among others, it emerged that deliberate detonations had supposedly occurred.

The Swedish Security Service’s investigation into the Nord Stream leaks served to stoke suspicions of sabotage, the agency reported last week.
