After Russia's invasion of Ukraine, Nord Stream and Europe's dependence on Russian gas have become increasingly questioned.
On September 26 this year, the leaks on Nord Stream 1 and 2 in the Baltic Sea were discovered.
In total, there are four leaks, two of which are in the Swedish economic zone.
The government has confirmed that two explosions took place and suspects that they are sabotage.
But it is not clear who or who are behind the deed.
