Iran's Foreign Minister has claimed America is not telling the full truth about the 9/11 terror attack, calling it "fake news."
A document published by the CIA claims al-Qaeda was supported by Tehran before the attack in 2001, according to Sputnik News.
But Iran's foreign minister Javad Zarif has claimed that Washington is attempting to "whitewash" the role of US allies.
He tweeted: "A record low for the reach of petrodollars: CIA & FDD fake news w/ selective AlQaeda docs re: Iran can't whitewash role of US allies in 9/11."
The CIA has released roughly 47,000 documents about the incident, including one which said "anyone who wants to strike America, Iran is ready to support him and help him with their frank and clear rhetoric."
Iran's Press TV news agency has also alleged that a US government commission which was looking into 9/11 claimed that al-Qaeda members had met with officials from Iran in Sudan between 1991 and 1992.
The news agency also alleged that the group ignored that 15 of the terrorists were from Saudi Arabia, and yet a court in New York ruled that Iran has to pay $7.5 billion (£5.73 billion) to families of the victims of the attack.
