Iraninfo-icon has accused the Central Intelligence Agency (CIA) of spreading "fake news" about the Islamic Republic with newly declassified files seized in the 2011 raid in Pakistaninfo-icon in which Al Qaeda chief Osama bin Laden was killed.

The CIA on Wednesday released 470,000 additional files found in May 2011 when United Statesinfo-icon (USinfo-icon) Navy SEALs burst into Bin Laden's compound in Abbottabad and shot him dead.

According to scholars from the Foundation for Defense of Democracies (FDD), who were allowed to see the trove before it was made public, the files shed new light on the murky relationship between the terror group and Iran.

Iranian Foreign Minister Mohammad Javad Zarif dismissed the allegations.

"A record low for the reach of petrodollars: CIA and FDD fake news with selective Al Qaeda docs re: Iran can't whitewash role of US allies in 9/11," he wrote on Twitterinfo-icon late on Thursday.

The release of the files comes as US President Donald Trumpinfo-icon's administration seeks to ramp up pressure on Iran, refusing to certify a landmark nuclear deal between Tehraninfo-icon and worldinfo-icon powers.

Iran denies any link to Al Qaeda.

The Fars newsinfo-icon agency, which is close to Iranian conservatives, said Thursday that the selective publication of documents by the CIA related to Al Qaeda was part of efforts "to put pressure on Iran".
