Ibn al-Shaykh al-Libi (Arabic: إبْنُ ٱلشَّيْخِ اللّيبي; ALFB transliteration: Ḁbnʋ ălŞɑỉƈ alLibi; born Ali Mohamed Abdul Aziz al-Fakheri, 1963 – May 10, 2009) was a Libyan national captured in Afghanistan in November 2001 after the fall of the Taliban; he was interrogated by the American and Egyptian forces. The information he gave under torture to Egyptian authorities was cited by the George W. Bush Administration in the months preceding its 2003 invasion of Iraq as evidence of a connection between Saddam Hussein and al-Qaeda. That information was frequently repeated by members of the Bush Administration, although reports from both the Central Intelligence Agency (CIA) and the Defense Intelligence Agency (DIA) strongly questioned its credibility, suggesting that al-Libi was "intentionally misleading" interrogators.
In 2006, the United States transferred al-Libi to Libya, where he was imprisoned by the government. He was reported to have tuberculosis. On May 19, 2009, the government reported that he had recently committed suicide in prison. Human Rights Watch, whose representatives had recently visited him, called for an investigation into the circumstances of his death;The New York Times reported that Ayman al-Zawahiri had asserted that Libya had tortured al-Libi to death.
In Afghanistan, al-Libi led the Al Khaldan training camp, where Zacarias Moussaoui and Ahmed Ressam trained for attacks in the United States. An associate of Abu Zubaydah, al-Libi had his assets frozen by the U.S. government following the September 11 attacks; it published a list of terrorists on September 26, 2002 who were covered by this restriction.
