Gaddafi regime's US-UK spy links revealed

Thousands of pieces of correspondence from US and UK officials were uncovered by reporters and activists in an office apparently used by Moussa Koussa, who served for years as Col Gaddafi's spy chief before becoming foreign minister.

The BBC's Kevin Connolly in Tripoli says the documents illuminate a short period when the Libyan intelligence agency was a trusted and valued ally of both MI6 and the CIA, with the tone of exchanges between agents breezy and bordering on the chummy.

"The CIA also sent the questions they wanted Libyan intelligence to ask and, from the files, it's very clear they were present in some of the interrogations themselves," he said.
