The Council of Europe says European nations need to introduce tougher laws to regulate the activities of foreign intelligence agents operating on their territories.
Council Chairman Terry Davis told reporters in Strasbourg Wednesday most of Europe is, "a happy hunting ground for foreign security services."
His comments came as he released a report detailing European nations' oversight of foreign intelligence activities.
At issue is the CIA, which is under fire in Europe over reports that it secretly flew terror suspects across the continent, and operated secret prisons in Eastern Europe to house and question the suspects. Washington denies any wrongdoing.
The report did not include any evidence of the existence of secret prisons in Europe.
Chairman Davis said Italy, Poland, Macedonia and Bosnia-Herzegovina did not provide requested information for the report.
Some information for this report was provided by AP and Reuters.
