It wasn’t alone: The agency had literally dozens of partners that helped in ways large and small. Only it’s never been clear just how many nations enabled CIA capture and torture; cooperated with it; or carried it out on behalf of the U.S. — until now.

A new report from the Open Society Foundation details the CIA’s effort to outsource torture since 9/11 in excruciating detail. Known as “extraordinary rendition,” the practice concerns taking detainees to and from U.S. custody without a legal process — think of it like an off-the-books extradition — and often entailed handing detainees over to countries that practiced torture. The Open Society Foundation found that 136 people went through the post-9/11 extraordinary rendition, and 54 countries were complicit in it.
