The BBC says it has had an advance look at a report on U.S. secret flights for terror suspects, and that the report will say up to 14 countries colluded with the CIA.

An excerpt:

The document will be presented to the Council of Europe by Swiss MP Dick Marty after a seven-month inquiry.

An advance copy seen by the BBC says there is also evidence to support suspicions that secret CIA camps are or were located in Poland and Romania.

The two countries have strongly denied the allegation in the past.

The BBC's Tim Franks in Paris, where the report will be issued, says the charges are potentially explosive but the difficulty remains in securing the proof.
