Tehran (IP)- A respected American investigative journalist unveiled how “skilled deep-water divers” from the US Navy planted C-4 explosives during a training exercise on Nord Stream 2 gas pipelines last June and then detonated the payload remotely three months later.

Iran PressAmerica: In a blog post, Seymour Hersh quoting one unnamed source claimed that the attack on Nord Stream 2 gas pipelines was carried out last September at the direction of President Joe Biden.  

The pipelines are multibillion-dollar infrastructure projects designed to carry Russian gas to Germany under the Baltic Sea.

Moscow has blamed the West for the unexplained explosions that caused the ruptures. Neither side has provided evidence. 

On Wednesday, Russia's foreign ministry said the United States had questions to answer over its role in explosions on the pipelines.

Hersh is a former New York Times and New Yorker reporter who won numerous awards for his investigative journalism, including about the Vietnam War and the 2004 Abu Ghraib scandal following the U.S. invasion of Iraq.

More recently, he ignited controversy with a report disputing the Obama administration's version of the 2011 killing of al Qaeda founder Osama bin Laden in a U.S. special forces operation, and another accusing Syrian rebels of staging an August 2013 sarin nerve agent attack on a Damascus suburb that killed hundreds of civilians.
