“In spring 2002, the ICRC [International Committee of the Red Cross] demanded that it be given access to prisoners under rendition. Instead, CIA lawyers further twisted legal boundaries by establishing a new category of prisoner: Persons Under Control, or PUC. Anyone held as PUC was automatically denied access to the ICRC, and even his existence was denied. The ICRC became extremely frustrated with U.S. obduracy. In January [16] 2004, after meeting U.S. officials in Washington, ICRC president Jacob Kellenberger went public saying he was deeply concerned about ‘the fate of an unknown number of people captured as part of the so-called global war on terror and held in undisclosed locations.’ ”
