Overview​

Pakistan's Inter-Services Intelligence (ISI) is one of the most powerful intelligence agencies in the world and has been deeply intertwined with both the CIA and jihadist movements since the Soviet-Afghan War of the 1980s. During that conflict, the ISI served as the CIA's primary conduit for channeling billions of dollars in weapons and funding to the Afghan mujahideen, including fighters who later formed the core of both the Taliban and al-Qaeda.

The ISI's connections to 9/11 center on several documented facts: a reported wire transfer of $100,000 from the ISI to lead hijacker Mohamed Atta; the ISI director's presence in Washington DC on September 11 meeting with the chairs of the US Senate and House Intelligence Committees; the ISI's documented role in creating and supporting the Taliban; and the 9/11 Commission's failure to meaningfully investigate any of these connections.

The ISI-9/11 connection is significant because it suggests that the attacks were not simply the work of a rogue terrorist organization operating independently, but may have involved the intelligence apparatus of a US ally -- an intelligence apparatus that had been funded and empowered by the CIA itself.

Key Activities & Evidence​

The $100,000 Wire Transfer to Mohamed Atta​

The most explosive allegation connecting the ISI to 9/11 is the reported wire transfer of $100,000 to Mohamed Atta, the operational leader of the 19 hijackers. The key claims:

  • Indian intelligence reportedly informed the US government that ISI Director Lt. General Mahmud Ahmed ordered the wire transfer to Atta.
  • The money was reportedly sent through Omar Saeed Sheikh (also spelled Ahmed Omar Saeed Sheikh), a British-born Pakistani who was a documented ISI asset.
  • The Times of India reported on October 9, 2001 that "US investigators now believe that the head of Pakistan's ISI, Lt. General Mahmud Ahmed, had about US$100,000 wired to WTC hijacker Mohammed Atta."
  • The Wall Street Journal also reported on the ISI connection to the wire transfer, citing the Times of India: "US authorities sought General Mahmud Ahmed's removal after confirming that $100,000 was wired to WTC hijacker Mohamed Atta from Pakistan by Ahmad Umar Sheikh at the insistence of General Mahmud."
  • The FBI confirmed that Atta received wire transfers totaling approximately $100,000 in the months before the attacks.
  • The Indian newspaper Daily Excelsior, quoting FBI sources, reported that the FBI's examination of the hard disk of a cellphone company Sheikh had subscribed to led to the discovery of the link between him and the ISI chief.

The 9/11 Commission's Final Report addressed the funding question by stating: "To date, the U.S. government has not been able to determine the origin of the money used for the 9/11 attacks. Ultimately the question is of little practical significance." This dismissal of the funding question has been widely criticized by researchers and 9/11 family members. Lorie Van Auken, whose husband died in the World Trade Center, was reportedly "irate" that the commission's narrative did not even mention the allegation about Ahmed's role in the wire transfer.

US investigators reportedly later suggested there was a name confusion between "Mustafa Muhammad Ahmad" (an alias for Mustafa al-Hawsawi, a known al-Qaeda financier held at Guantanamo Bay) and "Mahmud Ahmed" (the ISI chief). However, the Indian intelligence reporting specifically identified the ISI chief, not al-Hawsawi.

Lt. General Mahmud Ahmed in Washington on 9/11​

Lt. General Mahmud Ahmed, the Director General of the ISI, was in Washington DC on September 11, 2001. His presence and meetings are documented:

  • Mahmud Ahmed arrived in the United States on September 4, 2001, one week before the attacks, with the stated purpose of discussing easing US sanctions on Pakistan while meeting Pentagon and CIA officials.
  • On the morning of September 11, he was having breakfast at the US Capitol with Senator Bob Graham (Chairman of the Senate Intelligence Committee) and Representative Porter Goss (Chairman of the House Intelligence Committee). Also present were Pakistan's Ambassador to the US Maleeha Lodhi and Senator Jon Kyl.
  • The breakfast meeting was reportedly discussing Osama bin Laden and al-Qaeda when a staff member handed Goss a note about the first plane strike. Goss showed it to Graham, and the two senators said they would have to end the meeting because something urgent had come up.
  • According to General Mahmud Ahmed's own account, Graham and Goss appeared "greatly agitated and nervous."

The presence of the ISI chief -- the man reportedly responsible for ordering the wire transfer to Mohamed Atta -- at a meeting with the heads of US congressional intelligence oversight, discussing bin Laden, at the precise moment the attacks occurred has been cited by researchers as one of the most extraordinary coincidences of 9/11. Porter Goss, who was having breakfast with Ahmed that morning, was later appointed CIA Director by President George W. Bush in September 2004.

Omar Saeed Sheikh: The Intermediary​

Ahmed Omar Saeed Sheikh is the reported intermediary who transmitted the $100,000 from the ISI to Mohamed Atta. His background reveals deep connections to intelligence agencies:

  • British-born Pakistani -- Born in London on December 23, 1973, to Pakistani parents who had emigrated to the UK in 1968. Educated at the London School of Economics.
  • ISI asset -- According to a 2002 ABC News report, Sheikh began working for the ISI in 1993 after traveling to Bosnia. Multiple sources confirm his ISI connections.
  • MI6 connections -- Former Pakistani President Pervez Musharraf stated in his 2006 autobiography In the Line of Fire that Sheikh was recruited by MI6 while a student at the London School of Economics but "went rogue" and became a jihadi "double agent" in Bosnia.
  • Kidnapping of Daniel Pearl -- Sheikh was convicted in 2002 for the kidnapping and murder of Wall Street Journal reporter Daniel Pearl, who was reportedly investigating ISI connections to al-Qaeda and the 9/11 attacks at the time of his abduction. The Sindh High Court vacated the murder conviction in April 2020, reducing the sentence to seven years for kidnapping.
  • ISI protection allegations -- Reports indicate that Sheikh has been protected by Pakistan's ISI, which allegedly blocked full justice in the Pearl case.
  • Released by India under pressure -- Sheikh had been imprisoned in India for kidnapping Western tourists in 1994; he was released in December 1999 as part of a prisoner exchange during the Indian Airlines Flight 814 hijacking, an operation widely attributed to ISI-backed militants.

The connection between Pearl's murder and his investigation into ISI-9/11 links has been noted by multiple journalists and researchers. Pearl was investigating the connections between the ISI, al-Qaeda, and the nuclear black market when he was killed.

ISI's Creation and Support of the Taliban​

The ISI's role as the primary creator and supporter of the Taliban is well-documented:

  • The ISI created the Taliban in 1994 from Afghan refugee camps and Deobandi religious schools (madrassas) in Pakistan's Pashtun tribal areas. When their previous proxy, Gulbuddin Hekmatyar's Hezb-e Islami, lost popular support and failed to seize Kabul, the ISI shifted its backing to the Taliban.
  • Through the ISI, Pakistan armed, equipped, and supplied young fighters from jihadist madrassas in the Northwest Frontier Province to the Taliban movement.
  • Since the Taliban's creation, the ISI and Pakistani military provided financial, logistical, and military support, including direct combat support.
  • ISI officers were embedded with Taliban military units.
  • The ISI facilitated al-Qaeda's presence in Afghanistan under Taliban protection, providing the environment that allowed bin Laden to plan the 9/11 attacks.
  • The ISI continued to support the Taliban even after the US demanded Pakistan cut ties following 9/11.
  • The ISI's relationship with the Taliban was an extension of the US-ISI cooperation during the 1980s Soviet-Afghan War, when the CIA channeled approximately $3 billion through the ISI to Afghan mujahideen.

Mahmud Ahmed's Quiet Removal​

Lt. General Mahmud Ahmed was quietly asked to retire as ISI chief on October 7, 2001 -- the same day the US began bombing Afghanistan. Pakistan's Dawn newspaper reported on October 9, 2001, that Mahmud Ahmed was replaced after FBI investigators established credible links between him and Omar Sheikh, who had allegedly wired money to Mohamed Atta.

No charges were filed against Mahmud Ahmed. He was not arrested, not extradited, and not questioned publicly. He retired from the military and, according to reports, later became involved in the real estate business in Pakistan. His quiet removal -- rather than prosecution -- suggests a deliberate decision by the US government to manage the situation diplomatically rather than pursue justice.

The 9/11 Commission's Non-Investigation​

The 9/11 Commission, directed by Philip Zelikow, did not substantively investigate the ISI connections. The commission's final report:

  • Did not mention the reported wire transfer from the ISI to Atta
  • Did not address Lt. General Mahmud Ahmed's presence in Washington on 9/11
  • Stated that the origin of the hijackers' funding was "of little practical significance"
  • Did not interview Mahmud Ahmed or Omar Saeed Sheikh

A UPI analysis published on July 26, 2004, noted that the 9/11 report "sidesteps Pakistan" entirely. Family members of 9/11 victims had specifically asked the commission to investigate the ISI connection, but their requests were not addressed.

Senator Bob Graham, who co-chaired the earlier Congressional Joint Inquiry into 9/11, repeatedly stated that foreign government support for the hijackers was covered up. While Graham primarily focused on Saudi Arabia and the 28 Pages, the ISI connection represents another axis of foreign government involvement that was not pursued.

Key Figures​

  • Lt. General Mahmud Ahmed -- ISI Director General (1999-2001); reportedly ordered the wire transfer to Mohamed Atta; in Washington DC on 9/11; quietly retired after the connection was reported
  • Omar Saeed Sheikh -- British-Pakistani ISI asset who reportedly transmitted the $100,000 to Atta; convicted in the kidnapping and murder of journalist Daniel Pearl
  • Bob Graham -- Senator and Intelligence Committee Chairman who was having breakfast with Mahmud Ahmed on the morning of 9/11; later spent years fighting to expose foreign government involvement
  • Porter Goss -- House Intelligence Committee Chairman at the 9/11 breakfast meeting; later became CIA Director (2004-2006), appointed by George W. Bush
  • Pervez Musharraf -- Pakistani President who confirmed Sheikh's intelligence connections in his memoir In the Line of Fire
  • Hamid Gul -- Former ISI chief (1987-1989) who publicly stated that 9/11 was an inside job and that the ISI-CIA relationship was central to understanding the attacks
  • Philip Zelikow -- 9/11 Commission executive director who ensured the ISI connection was not investigated
  • Daniel Pearl -- Wall Street Journal reporter murdered while investigating ISI-al-Qaeda connections

Why This Group Matters​

The ISI connection to 9/11 matters because it points to state-level involvement in the attacks by a US ally whose intelligence service was created and funded by the CIA:

  • State sponsorship -- If the ISI funded the hijackers, 9/11 was not merely a non-state terrorist attack but involved a government intelligence agency
  • CIA-ISI nexus -- The ISI's decades-long relationship with the CIA raises questions about what the CIA knew about ISI support for al-Qaeda
  • Deliberate non-investigation -- The 9/11 Commission's failure to investigate the ISI connection, despite press reports and Indian intelligence, suggests a deliberate decision to protect the US-Pakistan relationship at the expense of accountability
  • Daniel Pearl's murder -- The killing of the journalist who was investigating these connections suggests active suppression of the evidence trail
  • Pattern of foreign intelligence involvement -- Combined with evidence of Saudi and Israeli intelligence connections, the ISI involvement indicates a multi-national intelligence dimension to 9/11 that the official narrative excludes
  • Breakfast on 9/11 -- The ISI chief's presence with the chairs of both intelligence committees at the moment of the attacks remains one of the most troubling unexamined facts of that day

Criticisms & Counter-Arguments​

  • Name confusion. US investigators reportedly concluded that the wire transfer was linked to Mustafa al-Hawsawi (alias Mustafa Muhammad Ahmad), an al-Qaeda operative, not ISI chief Mahmud Ahmed. The similarity in names allegedly caused the initial misidentification.
  • Indian intelligence bias. India and Pakistan are longstanding adversaries. Indian intelligence reports alleging ISI involvement in 9/11 may reflect India's interest in discrediting Pakistan rather than objective intelligence analysis.
  • The 9/11 Commission investigated funding. The commission's staff examined terrorist financing extensively and concluded that al-Qaeda's funding came through its own networks, not through state intelligence agencies.
  • Mahmud's visit was routine. The ISI chief's presence in Washington was part of a scheduled diplomatic visit to discuss US-Pakistan relations and the situation in Afghanistan, not an unusual occurrence.
  • No US prosecution. If the US government had evidence that the ISI funded 9/11, it would have pursued the matter. The absence of charges suggests the evidence was insufficient.
  • Correlation vs. causation. The ISI's relationship with the Taliban does not necessarily mean it directed or funded the 9/11 attacks specifically.
  • Bob Graham -- Was having breakfast with the ISI chief on the morning of 9/11; later spent years fighting to expose foreign government involvement
  • Philip Zelikow -- Controlled the 9/11 Commission that declined to investigate the ISI connection
  • The 28 Pages / Saudi Connection -- Another foreign government connection to the hijackers that was suppressed; Bob Graham fought to declassify these pages while the ISI connection remained unexamined
  • 9/11 Commission -- The investigation that said the origin of hijacker funding was "of little practical significance"
  • PNAC -- The neoconservative agenda that needed Pakistan as an ally for the Afghan war, creating incentive to suppress ISI connections
  • Urban Moving Systems -- Another foreign intelligence connection to 9/11 that was not investigated by the commission

Other Coverage Worth Reading​

  • Sibel Edmonds: FBI translator discovered evidence of foreign intelligence penetration and was gagged by the DOJ under state secrets privilege.
  • Coleen Rowley: FBI agent whose pre-9/11 warnings about Zacarias Moussaoui were blocked by FBI headquarters in what she called deliberate obstruction.
  • Christopher Bollyn: Investigative journalist who traced the 9/11 cover-up across multiple intelligence agencies and was arrested and tasered outside his home.
  • Susan Lindauer: CIA asset who warned of the 9/11 attacks months in advance, was arrested under the Patriot Act, and held for years without trial.
