Osama bin Laden sends a letter to al-Qaeda leader Abu Faraj al-Libbi, and US intelligence will learn about this a year or so later. This is one of the very few pieces of evidence known by US intelligence that suggests bin Laden is alive, after bin Laden escaped from Tora Bora, Afghanistan, in late 2001. Al-Libbi has been al-Qaeda’s operational commander since early 2003.
Guantanamo File Account – In April 2011, the non-profit whistleblower group Wikileaks will release the Guantanamo prison assessment file of al-Libbi, dated September 2008. According to this assessment, which is likely based on al-Libbi’s interrogations, al-Libbi receives a letter from bin Laden in October 2004 asking about al-Qaeda’s financial situation in Pakistan and especially Waziristan (part of Pakistan’s tribal region). Al-Libbi also gets a videotape of bin Laden’s speeches. (Note that the first video footage of bin Laden is publicly released in late October 2004 (see October 29, 2004).) Al-Libbi gets the letter and videotape from bin Laden’s courier, who first met up with al-Libbi in July 2003 (see July 2003-Mid-2004). [US Department of Defense, 9/10/2008]
Musharraf’s 2006 Book – In a 2006 book, Pakistani President Pervez Musharraf will similarly mention that al-Libbi “was in contact with Osama through a courier and the last letter he had received from Osama was sometime in December 2004. We have been looking for the couriers intensely.” [Musharraf, 2006, pp. 172] Al-Libbi will be captured in May 2005, and apparently he is interrogated by Pakistan for a few days, and then turned over and interrogated much more by the US (see May 2, 2005). So different interrogations may explain the slightly different months mentioned in each account. Bin Laden’s courier will later be revealed to be Ibrahim Saeed Ahmed, and the US effort to track him will eventually lead to bin Laden (see May 2, 2011).
