In France, the International Federation for Human Rights (FIDH) and the League of Human Rights (LDH) filed a complaint urging the French Public Prosecutor to investigate the alleged use of French airports by secret CIA flights transporting terrorist suspects. On 19 February, the UK National Air Traffic Services acknowledged that three CIA jets had traveled through the UK on a number of occasions, indicating that the UK authorities were aware of the so-called CIA torture flights. The UK police have reportedly started inquiries into the allegations.
