Washington, October 25 (RHC)-- A U.S. federal judge has ordered the Barack Obama administration to outline in detail its reasons for concealing as many as 2,100 photographs showing the torture of prisoners in Iraq and Afghanistan.

In 2009, Obama agreed to release the photos, but later changed his mind, saying they would "inflame anti-American opinion and put our troops in danger."

As part of a decade-long transparency case brought by the American Civil Liberties Union, the judge ordered the government to delineate, for each photograph, its reasons for keeping the images from the public. The photographs are reportedly more disturbing than the famous images of torture by U.S. forces at Abu Ghraib in Iraq.
