According to a report by the Open Society Foundations, Turkey participated at one point or another with the CIA's extraordinary rendition program. U.S. ambassador Ross Wilson revealed the involvement of the Incirlik airbase in a diplomatic cable dated June 8, 2006, which described Turkey as a crucial ally in the "global war on terror" and an important logistical base for the US-led war in Iraq. On June 14, 2006, Turkish foreign ministry officials told reporters: "The Turkish government and state never played a part the secret transfers ... and never will." According to evidence, the US base was a transit stop in taking detainees to secret prisons. The cable also stated: "We recommend that you do not raise this issue with TGS general staff pending clarification from Washington on what approach state/OSD/JCS/NSC security council wish to take."
