Koussa may have to answer for Lockerbie bombing

(Megrahi was freed in August 2009, on compassionate grounds, because he reportedly was suffering from terminal prostate cancer and had less than three months to live. However, he is still alive.)

Representatives from Scotland's Crown Office and detectives from Dumfries and Galloway Constabulary met with officials of the British Foreign Office in London on Monday to discuss interviewing Koussa.

"It was a very positive meeting and steps are being taken with a view to arranging a meeting with Mr. Moussa Koussa at the earliest opportunity in the next few days," the Crown Office said in a statement.

The British foreign secretary William Hague has said the government will encourage Koussa to cooperate with Scottish investigators. (Hague specified, however, that Koussa will not enjoy any immunity, despite his value as an intelligence official).

Moreover, Hague asserted that since Koussa is not under arrest he cannot be officially forced to testify about Libya’s sponsorship of terrorism.

"Moussa Koussa is not being offered any immunity from British or international justice," Hague said.

"He is not detained by us and has taken part in discussions with officials since his arrival, of his own free will. We will encourage Moussa Koussa to cooperate fully with all requests for interviews with law enforcement and investigation authorities, in relation both to Lockerbie, as well as other issues stemming from Libya's past sponsorship of terrorism, and to seek legal representation where appropriate."

Hague added there is "insufficient evidence to produce further prosecutions, but that may change in future".

In the meantime, Koussa has been providing information to British officials about the inner workings of Moammar Gaddafi’s regime and the ongoing civil war in Libya.
