Nearly 800 people have been held at Guantanamo Bay prison since prisoners begun arriving there in January 2002 and 91 still remain today.
All would be transferred somewhere else under President Obama's plan to close the facility. Half are facing criminal charges, while 35 have been deemed eligible for transfer to other countries. Another 10 have been determined to be "unreleasable."
The detainees are from more than a dozen countries, but most — 52, including 29 who've been cleared for release — are from Yemen. The detainees include Khalid Shaikh Mohammed, a Pakistani citizen who was "the principal architect" of the Sept. 11, 2001 terror attacks, according to the 9/11 Commission Report.
Abu Zubaydah, suspected of being an al-Qaida operative and 9/11 plotter, is also being held there. He was waterboarded and lost an eye while held by the CIA after his capture in 2002.
