Six decades before Norway helped the CIA destroy the Nord Stream gas pipelines, it gave the agency heavily-armed boats that it used to target North Vietnam, investigative journalist Seymour Hersh claimed on Wednesday. Norway's involvement in this secret war was deeper than previously reported, Hersh noted.

Hersh, a Pulitzer Prize-winning investigative journalist, claimed earlier this month that the CIA sabotaged the Nord Stream lines on President Joe Biden's orders. The Norwegian Secret Service and Navy reportedly helped CIA divers choose the correct spot to plant the explosives, and ferried the Americans out on a boat to the location, near Denmark's Bornholm island in the Baltic Sea.

Explaining why the US chose Norway as its partner in destroying the Russia-to-Germany gas lines, Hersh said on Wednesday that the "Norwegian Navy has a long and murky history of cooperation with American intelligence."
