Watch: Government profile reveals a glimpse of one of the first inmates in Guantanamo to be tortured.
When Zayn al-Abd Din Mohammed, a.k.a. Abu Zubaydah, was first captured by the United States in Pakistan and then imprisoned in Guantanamo Bay, the U.S. government claimed it had nabbed one of al-Qaida's top operatives. That turned out not to be entirely true.
According to a recently-released Guantanamo prisoner profile, Abu Zubaydah certainly facilitated terrorist training and activities in the Middle East but was far from one of al-Qaida's top commanders.
Take a look at Abu Zubaydah's Gitmo prisoner profile.
According to the documents, Abu Zubaydah began training militant recruits in Afghanistan and facilitating their travel abroad in 1989. He communicated with al-Qaida commanders, but was not one himself.
Abu Zubaydah was most active in planning attacks against Israel for various militant groups. Authorities say he may have had some knowledge of the bombings of U.S. embassies in Kenya and Tanzania in 1998.
The document also says that he "was generally aware of the impending 9/11 attacks, and possibly coordinated the training at Khaldan Camp of two of the hijackers."
Abu Zubaydah arrived at Guantanamo in September 2006.
According to the CIA Torture Report released in 2014, he was one of three detainees subjected to the practice of waterboarding, which is a torture technique designed to simulate drowning.
During his time in the prison, Abu Zubaydah was also deprived of sleep and clothing, slammed against a wall repeatedly, placed inside a small box with insects, and was denied medical treatment for injuries he sustained during his capture.
This photo, released by U.S. Central Command, shows Abu Zubaydah at an unspecified time and location.
While incarcerated, Abu Zubaydah has cooperated with prison authorities. He's become a cell block leader, speaking with prison staff and communicating prisoner grievances or concerns.
The profile also mentions that the former al-Qaida operative has "responded to most, if not all, lines of questioning by the debriefers, including providing detailed information on his terrorist activities and those of his associates."
It does not specify under what circumstances Abu Zubaydah cooperated.
Despite Abu Zubaydah's positive behavior, the U.S. government still maintains that he is a potential threat.
The document suggests that the former al-Qaida operative spent his time in prison honing skills he could use to perpetrate attacks against the U.S. and its allies. The government also believes Zubaydah still retains an extremist mindset, and because he no longer has any connections to family in the outside world, former colleagues could assist him in returning to terrorism.
Abu Zubaydah appeared at a government hearing last week and asked to be released, but no trial is scheduled.
