The plane, which landed twice in Croatia, is described in the report as the one used to transfer German national Khaled al Masri, wrongly suspected of terrorism, from the Macedonian capital of Skopje to Afghanistan in January 2004. Human Rights Watch has identified the plane as the one used by the CIA to transfer several detainees in and from Europe, Afghanistan, and the Middle East in 2003 and 2004, and which landed in Poland and Romania during direct flights from Afghanistan in 2003 and 2004.
The plane flew under two numbers at the time - N313P and N4476S.
The report mentions no other details about the two landings in Croatia, such as who was aboard the plane, or any other detail regarding its flights over Croatia.
AI says that the United States used private airliners as a cover for the secret transfer of terrorism suspects to other countries for interrogation and torture.
The CIA has been accused by the world media of transferring people suspected of terrorist activity, contrary to the usual legal procedure, to countries where they could be interrogated and tortured. AI believes that those were secret flights which enabled the disappearance of many "unsuitable" persons.
Washington has admitted to practicing the transfer of suspects outside the usual procedure, which it says is known as rendition, but it dismisses accusations that the suspects are transferred to countries where prisoner torture is practiced, the new agency dpa reports.
