A number of the September 11, 2001 survivors and relatives have called for declassification of intelligence files that could shed light on whether Saudi officials helped carry out the attacks.

American media reported that the survivors and the families of some of the victims sent a letter to US Attorney General William Barr in this regard.

A number of the survivors and relatives of the victims who filed a lawsuit in a federal court in New York accused the Saudi government of helping to coordinate the attacks against the World Trade Center and the Pentagon, which resulted in the death of about 3,000 Americans.

And Yahoo! News previously revealed in an exclusive report that the FBI mistakenly revealed the identity of a mysterious official at the Saudi embassy in Washington, who is suspected of helping two of the perpetrators of the attacks.

The disclosure came in a document filed by a FBI official last month by a federal court, in response to a lawsuit filed by the families of the September 11 victims, accusing the Saudi government of complicity in the attacks.

Although the document obscures the name of the Saudi official, his name was incorrectly mentioned in one of the paragraphs. The matter is related to the name of Musaed Ahmad Al-Jarrah, a former official in the Saudi Foreign Ministry who was assigned to the Saudi embassy in Washington, DC between 1999 and 2000.

The Ministry of Justice asked the court to withdraw the document from the public registry, as it indicated that it had been improperly deposited, according to Yahoo News.

Last May, NBC News said that the families of the victims now wanted to release more documents to clarify the degree of involvement of the Saudi official in assisting the perpetrators.

The disclosure of this name has revived many doubts about Saudi Arabia's links to the attacks, as part of a lawsuit filed by the families of the victims since 2003.
