GENEVA, Jumada I 24, 1434, Apr 5, 2013, SPA -- The U.N. human rights chief called on the United States on Friday to close down the Guantanamo prison camp, saying the indefinite imprisonment of many detainees without charge or trial violated international law, Reuters reported. Navi Pillay said the hunger strike being staged by some inmates at the Guantanamo Bay U.S. Naval Base in southeastern Cuba was a "desperate act" but it was "scarcely surprising". "We must be clear about this: the United States is in clear breach not just of its own commitments but also of international laws and standards that it is obliged to uphold," the U.N. High Commissioner for Human Rights said in a statement. About half of the 166 detainees there have been cleared for transfer either to home countries or third countries for resettlement, Pillay said. "As a first step, those who have been cleared for release must be released," she said. -- SPA 19:11 LOCAL TIME 16:11 GMT www.spa.gov.sa/1095013
