This report describes Amnesty International’s (AI) human rights concerns in Libya. Despite an amnesty in March 1988 and legal reforms since then, at least 467 political prisoners remain in detention. AI believes that some of those detained may be prisoners of conscience. Five such cases are: Ali Muhammad Al Akrami, Al ‘Ajili Muhammad Abdul Rahman Al Azhari, Ali Muhammad Al Qajiji, Salih Omar Al Qasbi and Muhammad Al Sadiq Al Tarhouni. AI is particularly concerned at the appa apparent continuation of arbitrary arrest and incommunicado detention i Libya. The appendices comprise three lists of detainees as well as an outline of legislation used to limit freedom of expression and to punish prisoners of conscience and political prisoners.
