The EU’s top diplomat says the Nord Stream leaks were the result of “a deliberate act”.

The leaks in the Nord Stream gas pipelines under the Baltic Sea were the result of “a deliberate act”, the European Union’s top diplomat said on Wednesday, joining a growing chorus of European leaders speaking of sabotage.

Three separate leaks discovered on Monday in the Nord Stream 1 and Nord Stream 2 pipelines from Russia to Germany “are not a coincidence and affect us all,” said Josep Borrell Fontelles, the EU’s high representative for foreign affairs and security. in a sentence.

Brussels would support an investigation, he added, and “take additional steps to increase our resilience on energy security.”

European officials have been deeply disturbed by pipeline breaks. Although the leaks will not immediately affect Europe’s energy supply, they underscore the vulnerability of the continent’s energy infrastructure. Top Polish and Ukrainian leaders blamed Moscow for the leaks, without providing evidence, while Russian state media suggested US or Ukrainian involvement.

Sweden’s security opened an investigation into the matter, calling the leaking acts “serious sabotage” and saying it could not rule out that a foreign government was behind it.

Borrell said the deliberate disruption of Europe’s energy infrastructure “is absolutely unacceptable and will be met with a strong and united response.”

The comments resonated a warning posted on Twitter Tuesday night by Ursula von der Leyen, the president of the EU’s executive arm, calling the leaks a “sabotage action”, adding that it was “main” to carry out an investigation.

The European Union lacks formal investigative powers, but officials said it would support investigations by national authorities.

On Wednesday, Kremlin spokesman Dmitri S. Peskov called the accusations of Russian involvement “predictably stupid and absurd,” again pointing the finger at the United States.

The immediate impact of leaks on your power supply is expected to be limited. Although filled with gas, none of the pipelines carried gas to Europe. Nord Stream 2 had not been authorized to operate, and Nord Stream 1 has been virtually cut off since August by Gazprom, the Kremlin-controlled energy giant.

Still, the leaks exacerbated Europe’s nervousness in its escalating energy war with Russia. Since the invasion of Ukraine, President Vladimir V. Putin of Russia has been tinkering with the continent’s energy supplies, turning off taps and ratcheting up tensions in response to European support for Ukraine.

The extent of the damage became clear on Tuesday, the day of the official opening of the Baltic Pipe project, a new gas pipeline that transports fuel from Norway to Poland through Denmark, which has been built as part of the European Union’s plan to stop Russian fossil fuels.

Danish and Polish leaders said the timing was not a coincidence. Swedish seismologists said they detected large underwater explosions Monday near the site of the leaks, with President Biden’s national security adviser Jake Sullivan calling the incident “apparent sabotage.”

Prime Minister Mateusz Morawiecki of Poland said authorities do not know the details of what happened “but we can clearly see that it is an act of sabotage.”

Denmark’s Prime Minister, Mette Frederiksen, echoed that judgment. “It’s hard to imagine that it’s accidental,” she told reporters, as she refused to place blame.

Finnish Foreign Minister Pekka Haavisto said on Wednesday that Finnish authorities will investigate “all ship movements in the Baltic Sea and try to find out what kind of movement has taken place in the immediate vicinity of pipelines.”

“There are several possibilities, but the magnitude of this event is such that surely some government actor is behind it,” he told the newspaper. Helsingin Sanomat.
