Jordanian intelligence (the GID) makes a communications intercept deemed so important that King Abdullah’s men relay it to Washington, probably through the CIA station in Amman. To make doubly sure the message gets through it is passed through an Arab intermediary to a German intelligence agent. The message states that a major attack, code named “The Big Wedding,” is planned inside the US and that aircraft will be used. “When it became clear that the information was embarrassing to Bush administration officials and congressmen who at first denied that there had been any such warnings before September 11, senior Jordanian officials backed away from their earlier confirmations.” The Christian Science Monitor will call the story “confidently authenticated” even though Jordan has backed away from it. [International Herald Tribune, 5/21/2002; Christian Science Monitor, 5/23/2002] It has been reported elsewhere that in July 2001, Jordan warns the US that al-Qaeda is planning an attack inside the US, but it is unknown if this is referring to the same warning or a separate one (see July 2001).
In late July 2001, the king of Jordan will offer the US to send two battalions of Jordanian special forces to Afghanistan to eliminate al-Qaeda havens there (see July 24, 2001). Also in July 2001, Jordan briefly detains and interrogates Mohammed Haydar Zammar, who is a member of the Hamburg cell with three of the 9/11 hijackers (see July 2001). Zammar appears to have foreknowledge of the 9/11 plot around this time (see August 2001).
August 2001: Moroccan Informant Warns US of Large Scale, Imminent Attack in New York
In 1999, a Moroccan named Hassan Dabou infiltrated al-Qaeda for the Moroccan intelligence agency. He was sent to Afghanistan, posing as an Islamic radical on the run from the Moroccan government. While there, he was able to grow close to bin Laden. He heard bin Laden repeatedly vent his anger at the failure of the World Trade Center bombing in 1993 (see February 26, 1993). Bin Laden was “very disappointed” that the towers did not fall. Dabou heard that bin Laden had planned “something spectacular” involving “large scale operations in New York in the summer or fall of 2001.” Moroccan intelligence passed this information to US. Around this time, US intelligence is so interested that they call Dabou to Washington to report on this information in person. Dabout makes the trip in secret, but apparently his cover is blown and he is unable to go back and gather more intelligence. Dabou is still in Washington cooperating with US intelligence agents when 9/11 occurs. After 9/11 he will remain in Washington, get a new identity, and continue to work with US intelligence.

August 2001: Russia Warns US of Suicide Pilots
Russian President Vladimir Putin warns the US that suicide pilots are training for attacks on US targets. [Fox News, 5/17/2002] The head of Russian intelligence Nikolai Patrushev also later states, “We had clearly warned them” on several occasions, but they “did not pay the necessary attention.” [Agence France-Presse, 9/16/2001] A Russian newspaper on September 12, 2001, will claim, “Russian Intelligence agents know the organizers and executors of these terrorist attacks. More than that, Moscow warned Washington about preparation to these actions a couple of weeks before they happened.” Interestingly, the article will claim that at least two of the militants were Muslim radicals from Uzbekistan.

August 2001: Persian Gulf Informant Gives Ex-CIA Agent Information About ‘Spectacular Terrorist Operation’
Former CIA agent Robert Baer is advising a prince in a Persian Gulf royal family, when a military associate of this prince passes information to him about a “spectacular terrorist operation” that will take place shortly. He is given a computer record of around 600 secret al-Qaeda operatives in Saudi Arabia and Yemen. The list includes ten names that will be placed on the FBI’s most wanted terrorists list after 9/11. He is also given evidence that a Saudi merchant family had funded the USS Cole bombing on October 12, 2000, and that the Yemeni government is covering up information related to that bombing. At the military officer’s request, he offers all this information to the Saudi Arabian government. However, an aide to the Saudi defense minister, Prince Sultan, refuses to look at the list or to pass the names on (Sultan is later sued for his complicity in the 9/11 plot in August 2002). Baer also passes the information on to a senior CIA official and the CIA’s Counter Terrorism Center, but there is no response or action. Portions of Baer’s book describing his experience wil be blacked out, having been censored by the CIA. [Baer, 2002, pp. 55-58; Financial Times, 1/12/2002]
Early August 2001: Britain Warns US Again; Specifies Multiple Airplane Hijackings
Britain gives the US another warning about an al-Qaeda attack. The previous British warning on July 16, 2001 (see July 16, 2001), was vague as to method, but this warning specifies multiple airplane hijackings. This warning is said to reach President Bush. [Sunday Herald (Glasgow), 5/19/2002]
August 8-15, 2001: Israel Reportedly Warns of Major Assault on the US
At some point between these dates, Israel warns the US that an al-Qaeda attack is imminent. [Fox News, 5/17/2002] Reportedly, two high-ranking agents from the Mossad come to Washington and warn the FBI and CIA that from 50 to 200 terrorists have slipped into the US and are planning “a major assault on the United States.” They say indications point to a “large scale target,” and that Americans would be “very vulnerable.” They add there could be Iraqi connections to the al-Qaeda attack. [Daily Telegraph, 9/16/2001; Ottawa Citizen, 9/17/2001; Los Angeles Times, 9/20/2001] The Los Angeles Times later retracts its story after a CIA spokesperson says, “There was no such warning. Allegations that there was are complete and utter nonsense.” [Los Angeles Times, 9/21/2001] Other newspapers do not retract it.
August 23, 2001: Mossad Reportedly Gives CIA List of Terrorists Living in US; at Least Four 9/11 Hijackers Named
According to German newspapers, the Mossad gives the CIA a list of 19 terrorists living in the US and say that they appear to be planning to carry out an attack in the near future. It is unknown if these are the 19 9/11 hijackers or if the number is a coincidence. However, four names on the list are known, and these four will be 9/11 hijackers: Nawaf Alhazmi, Khalid Almihdhar, Marwan Alshehhi, and Mohamed Atta. [Die Zeit (Hamburg), 10/1/2002; Der Spiegel (Hamburg), 10/1/2002; BBC, 10/2/2002; Ha’aretz, 10/3/2002] The Mossad appears to have learned about this through its “art student spy ring.” Yet apparently, this warning and list are not treated as particularly urgent by the CIA and the information is not passed on to the FBI. It is unclear whether this warning influenced the decision to add Alhazmi and Almihdhar to a terrorism watch list on this same day, and if so, why only those two. [Der Spiegel (Hamburg), 10/1/2002] Israel has denied that there were any Mossad agents in the US. [Ha’aretz, 10/3/2002]
August 24, 2001: Foreign Intelligence Warns US of Al-Qaeda Plot to Attack within US
The 9/11 Commission later will note that at this time, an unnamed foreign intelligence “service report[s] that [al-Qaeda deputy leader] Abu Zubaida [is] considering mounting terrorist attacks in the United States, after postponing possible operations in Europe. No targets, timing or method of attack [are] provided.” Newsweek will suggest that most or all of this information may have come from a US debriefing of al-Qaeda bomber Ahmed Ressam in May 2001 (see May 30, 2001). Newsweek will note that it is a common occurrence for foreign intelligence agencies to “simply rereport to the CIA what it had originally learned from the FBI through separate channels.” Still, even “the multiple channels for Ressam’s warnings [do] little to change thinking within the FBI or CIA…” [Newsweek, 4/28/2005; US District Court of Eastern Virginia, 5/4/2006, pp. 6 
] However, it is possible the information could be more than a mirror of what Ressam said, since a number of Western intelligence agencies are monitoring Zubaida’s phone calls before 9/11 (see October 1998 and After).
August 29, 2001: Cayman Islands Letter Warns of ‘Major Terrorist Act against US via an Airline or Airlines’
A Cayman Islands radio station receives an unsigned letter claiming that three men from either Pakistan or Afghanistan who are living in the Cayman Islands are agents of Osama bin Laden. These three men were briefly arrested in June 2001 for discussing hijacking attacks in New York City (see June 4, 2001). The letter’s anonymous author warns that the men “are organizing a major terrorist act against the US via an airline or airlines.” On September 6, the letter will be forwarded to a Cayman government official, but no action will be taken until after 9/11. When the Cayman government notifies the US is unknown. Many criminals and/or businesses use the Cayman Islands as a safe, no tax, no-questions-asked haven to keep their money. The author of the letter will meet with the FBI shortly after 9/11 and will claim his information was a “premonition of sorts.” The three men will later be arrested. What happens to them after their arrest is unclear. [Miami Herald, 9/20/2001; Los Angeles Times, 9/20/2001; MSNBC, 9/23/2001]
August 30, 2001-September 4, 2001: Egypt Warns Al-Qaeda Is in Advanced Stages of Planning Significant Attack on US
According to Egyptian President Hosni Mubarak, Egyptian intelligence warns American officials that bin Laden’s network is in the advanced stages of executing a significant operation against an American target, probably within the US. [Associated Press, 12/7/2001; New York Times, 6/4/2002] He says he learned this information from an agent working inside al-Qaeda. US officials will deny receiving any such warning from Egypt. [ABC News, 6/4/2002]
