Divers reporting to the commander-in-chief of the Ukrainian armed forces were planning an attack on Nord Stream, according to documents reported by the US media. An intelligence agency of an unspecified European country had informed the CIA, four months after the start of Russia's invasion of Ukraine.

The operation was supervised by General Valeriy Zaluzhniy without the knowledge of Ukrainian President Volodymyr Zelensky. The Nord Stream 1 and 2 pipelines, which were supposed to transport natural gas from Russia to Germany, were hit by underwater explosions on September 26.
