The CIA operated a secret torture centre in Poland after 9/11

From the Open Society Foundations website:

The European Court of Human Rights has finally officially confirmed the facts of a story that the U.S. and European governments have sought to deny for more than a decade: The U.S. Central Intelligence Agency operated a secret torture center on Polish soil in the aftermath of the attacks on the United States on September 11, 2001. 

In a historic ruling, the court concluded beyond reasonable doubt that Abd al-Rahim al-Nashiri—represented by the Open Society Justice Initiative—and Abu Zubaydah were held in secret and tortured by the CIA at a military base called Stare Kiejkuty in violation of the European Convention on Human Rights.
