Despite "constructive" negotiations over jailed Australian lawyer Melinda Taylor, Libya appears to be convinced of her guilt as a conduit for secret communications between Muammar Gaddafi's son Saif al-Islam Gaddafi and hunted members of the former regime.
The case against Taylor was detailed in a letter to the United Nations Security Council obtained by Britain's Guardian newspaper, alleging the use of coded messages and miniature video cameras hidden in a pen and a watch.
Taylor and three other members of an International Criminal Court team were arrested on June 7 during a visit to Saif in the mountain town of Zintan, where he is being held by a powerful local militia.
Foreign Minister Bob Carr, who visited Tripoli last week to push for Taylor's freedom, has adopted what he described as a "muted response during a delicate time".
He said talks between the court and Libyan officials had been very constructive, following a statement from the ICC expressing its deep regret for "any events that may have given rise to concerns" and assurances it did not intend to undermine Libyan national security.
