Council of Europe demands truth on CIA 'black sites'

Paris (CNN) -- The human rights commissioner for the Council of Europe urged countries that have hosted secret CIA prisons to come clean Monday, as the 10th anniversary of 9/11 approaches.

Thomas Hammarberg said Poland, Romania and Lithuania were among at least seven countries that hosted "black sites" for "enhanced interrogation" during the "war on terror."

"Darkness still enshrouds those who authorized and ran the black sites on European territories," he said. "The full truth must now be established and guarantees given that such forms of co-operation will never be repeated."

CIA officials have acknowledged the rendition program, but refused to discuss details and denied violating any laws. Efforts to challenge the agency and get details about it in U.S. courts have been turned aside.
