In 1994 , Gadafi fired Abdullah Senussi as head of the Libyan intelligence agency and reorganized the agency under a newly formed External Security Organization ( ESO ) , headed by Moussa Koussa from 1994 to 2009 . During this phase Moussa Koussa was the key figure in the normalization of relations between Libya and many NATO nations , including the United States and the United Kingdom . He played a crucial role in securing the release of Abdelbaset al-Megrahi , the alleged Pan Am Flight 103 bomber , whose involvement in the story is quite controversial . Several legal experts as well as the UN observer at the Lockerbie trial have vehemently challenged the verdict that convicted Megrahi .
