Libya documents 'reveal spy secrets'
3 September 2011 Last updated at 17:52 BST
US and UK spy agencies built close ties with their Libyan counterparts during the so-called War on Terror, according to papers discovered in Tripoli.
Thousands of documents were uncovered by reporters and activists in an office apparently used by Moussa Koussa, who served as Col Gaddafi's spy chief before becoming foreign minister.
The papers suggest the CIA abducted several suspected militants from 2002 to 2004 and handed them to Tripoli.
The UK's MI6 also apparently gave the Gaddafi regime details of dissidents.
The documents have not been seen by the BBC and have not been independently verified.
