A revelatory report by Seymour Hersh claims that U.S. divers installed explosives under the Nord Stream pipelines during a military exercise last summer before detonating them in late September. Raymond McGovern, a former CIA analyst, supported Hersh's account while addressing a UN Security Council meeting on the Nord Stream pipeline incidents on February 21, where Russia requested a UN-led inquiry into the explosions. McGovern said both a U.S. State Department spokesperson and White House spokesmen have said the report was fake news, but they did not provide any evidence.
