KYIV, March 8 – NATO Secretary General Jens Stoltenberg has said that it is still unclear who carried out the attack on the Nord Stream and Nord Stream 2 gas pipelines in September last year, and it is necessary to wait for the completion of national investigations.

“We do know is that there was an attack against the Nord Stream pipelines, an act of sabotage, but we have not been able to determine who was behind. There are ongoing national investigations, and I think it is right to wait until those are finalized before we say anything more about who was behind,” Stoltenberg told reporters before a meeting of EU defense ministers in Stockholm.
