Al-Masri, who was born in Kuwait, told the committee that he was arrested by U.S. agents on the Macedonian border while on vacation. He said he was kept at a hotel in Skopje for several weeks before being flown to Afghanistan and jailed for five months. He said he was flown back to Europe in May 2004 and released in Albania.

Fava said the bulk of the clandestine CIA flights passed through Germany and Spain, where the United States has several air bases. Neither government had any comment.

The European Union also declined to address the committee's preliminary report.

"We have no comment. We will wait for the investigation to finish," said Friso Roscam Abbing, spokesman for EU Justice Commissioner Franco Frattini.
