Zarif: US trying to...

It claimed that Iran and Al-qaeda could overlook their differences and join forces when it came to confronting the US.

The US government’s 9/11 Commission has made similar allegations, saying Iranian officials met with Alqaeda leaders in Sudan in either 1991 or early 1992.

Ignoring the fact that 15 of the 19 hijackers involved in the 9/11 attacks were Saudi nationals, the commission makes yet another wild claim, alleging that eight of the hijackers who kept passengers on the hijacked flights under control passed through Iran before arriving in the US.

Last year, a New York court ordered Iran to pay $7.5 billion in damages to the families of the 9/11 victims.

Perhaps, former US secretary of state Hillary Clinton has given the clearest response to this question.

Clinton has admitted on numerous occasions, including in a 2010 Fox News interview, that the US government and its intelligence agencies created Al-qaeda.

Saudi Arabia’s role in the deadly 9/11 attacks became more clear last year, when the US finally decided to declassify parts of the 9/11 congressional report it had kept secret for years.

The kingdom warned that it would liquidate billions of dollars of US assets when Congress passed a piece of legislation that would allow the families of the 9/11 victims to sue Saudi Arabia.
