More than 700 leaked secret files on the Guantánamo detainees lay bare the inner workings of America's controversial prison camp in Cuba.
The US military dossiers, obtained by the New York Times and the Guardian, reveal how, alongside the so-called "worst of the worst", many prisoners were flown to the Guantánamo cages and held captive for years on the flimsiest grounds, or on the basis of lurid confessions extracted by maltreatment.
The 759 Guantánamo files, classified "secret", cover almost every inmate since the camp was opened in 2002. More than two years after President Obama ordered the closure of the prison, 172 are still held there.
The files depict a system often focused less on containing dangerous terrorists or enemy fighters, than on extracting intelligence. Among inmates who proved harmless were an 89-year-old Afghan villager, suffering from senile dementia, and a 14-year-old boy who had been an innocent kidnap victim.
