The Kremlin said on Friday there was a need for thorough international investigation into ruptures of the Russian-led Nord Stream undersea gas pipelines.
Kremlin spokesman Dmitry Peskov declined to comment on a statement by Russia's top spy that Moscow had materials indicating that the West had a role in the breaches of the Baltic Sea pipelines.
Russian has said that the ruptures appear to be the result of state-sponsored "terrorism".
The European Union is investigating and has said it suspects sabotage.
