The White House and CIA are denying a new report by a prize-winning American journalist who claims the United States was behind the sabotage of the Nord Stream 1 and 2 pipelines off the coast of Denmark in September last year. In his self-published report, Seymour Hersh says that the bombing was approved by the Biden administration and carried out by the U.S. Navy with help from the Norwegian navy and secret service. How reliable is the story? What would be America's motive for sabotaging the pipeline? And how is the international community responding – especially among Washington's European allies?
