"We believe that the incident needs to be thoroughly investigated, and those responsible must be held accountable. In particular, we need to find out if members of the German government were aware of this incident before or after it occurred. We have called for the establishment of an inquiry commission in the European Parliament and are now calling for a UN investigation," Chrupalla told Turkish newspaper Aydinlik.
The Nord Stream and Nord Stream 2 gas pipelines, built to deliver gas under the Baltic Sea from Russia to Europe, were hit by explosions on September 26, 2022. Germany, Denmark and Sweden have not ruled out deliberate sabotage.
The Russian Prosecutor General's Office has opened an investigation into it as an act of international terrorism. Russia has repeatedly requested data on other countries' investigations into the explosions, but never received it, Kremlin spokesman Dmitry Peskov has said.
