Yahoo! News 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 aiding two of the September 11, 2001 attacks.

The disclosure came in a document submitted by a FBI official last month to 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.

According to Yahoo News, Ahmed Al-Jarrah's duties included overseeing the activities of Ministry of Islamic Affairs employees in Saudi Arabia in mosques and Islamic centers funded by Saudi Arabia within the United States.

And the Yahoo! Nabuz website quoted a spokesman for the families of the September 11 victims, who considered the disclosure a major breakthrough in the case that had been filed for years, adding that it provided for the first time a clear assurance that the FBI agents investigating the attacks believed that they had discovered a link between the kidnappers and the Saudi embassy in Washington.

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.

Al-Jazeera correspondent in Virginia Mohammed Al-Ahmad said that this disclosure actually revives many doubts about the Kingdom of Saudi Arabia's links to the September 11 attacks as part of the lawsuit filed by the families of the victims since 2003.

The reporter noted that these claims gained momentum in 2016 when Congress passed the Justa Law, which allows Americans to sue foreign governments for terrorism charges.
