The UN has called on the US government to close its prison at Guantanamo Bay. In its final report on US compliance with international torture conventions, the U.N. Committee Against Torture said the US should close all down the Cuba prison and avoid using secret prisons in other parts of the world. The committee also said the US should outlaw the use of several of its known interrogation techniques, including sexual humiliation, mock drownings and the use of dogs to induce fear.
