Germany, Hungary, Italy, Morocco, Norway, Poland, Romania, Spain and Sweden have all been linked to the CIA's use of planes for the transit, or rendition, of prisoners allegedly subjected to extra-judicial detention and torture.
In Olso, the Norwegian government summoned a US embassy official over the landing in Oslo on 20 July of a plane which according to media reports was one of those the CIA used to transport the suspected extremists.
According to a foreign ministry spokesman, the official "denied that the plane in question had been used by the American authorities at the time".
