Explainer | Global mystery: what’s known about the Nord Stream pipeline explosions
- Undersea gas pipelines from Russia to Germany were sabotaged on the night of September 26, 2022
- Moscow denies being behind the incident and has accused the US and Britain of involvement

It’s a major international mystery with global consequences: who was behind the explosions that damaged the Nord Stream gas pipelines last year in the Baltic Sea?
The answer has broad implications for European energy security but could also threaten Western unity over backing Ukraine in defending itself from Russia’s invasion. Or, it might shatter Russian and Chinese attempts to fix the blame on a hypocritical West.
Yet, nearly six months after the sabotage on the Russia-to-Germany pipelines, there is no accepted explanation. And a series of unconfirmed reports variously accusing Russia, the United States and Ukraine are filling an information vacuum as investigations into the blasts continue.
A look at the pipelines and what’s known about the explosions.
What are the Nord Stream pipelines?
The pipelines, known as Nord Stream 1 and Nord Stream 2, are majority-owned by Russia’s state-run energy giant Gazprom and used to transport natural gas from Russia to Europe under the Baltic to their termini in Germany.
