Russia’s foreign ministry on Thursday said ruptures to the Nord Stream pipelines that have caused gas leaks off the coasts of Denmark and Sweden occurred in territory that is “fully under the control” of US intelligence agencies.

Foreign Ministry spokeswoman Maria Zakharova told a pro-Kremlin broadcast that Washington had “full control” over the waters around Denmark and Sweden where four leaks have been detected on the Nord Stream 1 and Nord Stream 2 pipelines, which cross the floor of the Baltic Sea between Russia and Germany.

“It happened in the trade and economic zones of Denmark and Sweden. There are NATO-centric countries,” Zakharova said an interview with the Soloviev Live online broadcast on Thursday. “They are countries that are completed controlled by the US intelligence services.”

Nord Stream sabotage not an attack on Sweden, foreign minister says

Denmark is a member of the NATO military alliance, while Sweden’s membership is pending after it abandoned its historic policy of non-alignment following Russia’s invasion of Ukraine.

Zakharova did not provide evidence of US control over Sweden and Denmark.

Russia frequently rails against American influence and military support for Europe.

The European Union suspects sabotage was behind the gas leaks on the subsea Russian pipelines to Europe and has promised a “robust” response to any intentional disruption of its energy infrastructure.

While neither pipeline was in use at the time of the suspected blasts, they were filled with gas that has been spewing out in the Baltic Sea since ruptures were first detected on Monday.
