Dick Marty, the Swiss investigator for the Council of Europe, said in his report that seven council member states could be held responsible for human rights violations.
"It is now clearâ€¦ that authorities in several European countries actively participated with the CIA in these unlawful activities. Other countries ignored them knowingly, or did not want to know," said. Mr. Marty who released his findings in Paris earlier today.
Marty said it is possible that the rights of specific suspects were violated in Sweden, Bosnia and Herzegovina, the United Kingdom, Italy, the former Yugoslav Republic of Macedonia, Germany and Turkey.
Several more countries colluded, actively or passively, in the detention or transfer of unknown persons, he said.
ABC News reported last year that Romania and Poland were two of the countries that had allegedly housed terror suspects. The Polish Minister of Defense, at the time, denied that any secret prisons were in his country. Marty's report concluded that both Poland and Romania housed prisoners at secret detention centers.
Marty also added that 'staging points' for the CIA flights were located in Germany, Turkey, Spain and Cyprus. He cited that the illegal flights transporting prisoners also made stops in the UK, Ireland, Portugal, Greece and Italy.
While Marty faults the U.S. for creating "this reprehensible network," he also faults the European countries for their "intentional and grossly negligent collusion," adding that the claim that Europe was a victim of secret CIA plots "does not seem to correspond to reality."
