Al-Qaeda leader Hassan Ghul is secretly transferred from US custody to Pakistani custody. The Pakistani government will later release him and he will apparently rejoin al-Qaeda. In early 2004, Ghul was captured in Iraq and put in the CIA’s secret prison system (see January 23, 2004). He became a “ghost detainee” because the US refused to admit they even held him. In 2006, the Bush administration decides to close most of the CIA’s secret prisons and transfer most of the important al-Qaeda prisoners to the Guantanamo prison. But Ghul is given to the Pakistani government instead, apparently as a goodwill gesture. According to a 2011 article by the Associated Press, “[T]he move frustrated and angered former CIA officers, who at the time believed Ghul should have been moved to Guantanamo along with 14 other high-value detainees” (See September 2-3, 2006). The ISI, Pakistan’s intelligence agency, promises that it will make sure Ghul is never released. But after only about a year, Pakistan will secretly let Ghul go and he apparently will return to working with al-Qaeda (see (Mid-2007)). [Associated Press, 6/15/2011] Ghul is given to Pakistan even though he is linked to a Pakistani militant group supported by the ISI, Pakistan’s intelligence agency, and the ISI had a history of protecting him from arrest (see (2002-January 23, 2004)). Also, Ghul is released even though he told US interrogators key information about Osama bin Laden’s courier that will eventually prove key to the discovery of bin Laden’s location (see Shortly After January 23, 2004 and Late 2005).
