According to Deutsche Welle:
According to a European Union investigator, the CIA has admitted to sending at least 50 terror suspects since 2001 to countries where they could be tortured. Claudia Fava, an Italian member of the European Parliament, said those figures were given to his team during last week’s visit to the United States. The CIA is accused of flying suspects to third countries via European states. However Flava said he could not say whether suspects had been flown through European airpace or even picked up in Europe. According to Flava US intelligence officials had also said that the CIA ran secret prisons in Europe, Asia and Africa.
