“As for the damage that was caused to the pipeline ... Frankly, there is a lot of speculation on this score, however, until the official investigation is completed, no one can determine with certainty what exactly happened there,” RIA Novosti quotes him as saying.

Earlier, the press secretary of the President of Russia Dmitry Peskov admitted that the incident with a gas leak at the Nord Stream could be a terrorist attack.

The official representative of the Russian Foreign Ministry, Maria Zakharova, called what happened at Nord Stream a provocation and sabotage.
