Khalid El-Masri is a German citizen who was detained in Skopje, flown to Afghanistan, interrogated and tortured by the CIA for several months, and then released in remote Albania in May 2004 without having been charged with any offense. This was apparently due to a misunderstanding that arose concerning the similarity of the spelling of El-Masri's name with the spelling of suspected terrorist Khalid al-Masri. Germany had issued warrants for 13 people suspected to be involved with the abduction, but dropped them in September 2007.
