American CIA had already warned its concerned officials, including Europeans, weeks ago that the Nord Stream pipes could be attacked.
Explosions have caused three huge fissures in two key gas links that Western leaders say are the result of sabotage.
Nord Stream 1 and Nord Stream 2 pipelines supply Russian gas to different European countries.
CIA Agents sent a ‘strategic warning’ to European allies including Germany over the summer that the pipes were at risk.
The warning, however, was not time specific and did not pinpoint a location for an attack.
The main suspicion for the attack has fallen on the Kremlin – with European officials claiming that ‘no-one is thinking this is anything other than Russian sabotage’. But allies currently lack enough hard evidence to publicly blame Moscow.
