Russia intends to call a United Nations Security Council meeting over damage to the gas pipelines, Foreign Ministry spokeswoman Maria Zakharova said in a statement on Telegram.
In the Baltic Sea, gas was still bubbling from the Nord Stream 1 pipeline, the Swedish Coast Guard said in an email.
"There are good teams in place to handle pipeline accidents, there are emergency pipe inventories and experts for onshore and offshore," Jens Schumann, managing director of gas pipeline grid company Gasunie Deutschland, said.
European gas prices rose following news of the leaks.
The new Nord Stream 2 pipeline had yet to enter commercial operations.
