In Cuba the state has a virtual monopoly of press and broadcast media and tight restrictions apply to the internet. Anyone who expresses views critical of the government runs the risk of harassment, arbitrary detention and criminal prosecution. Dozens of prisoners of conscience continue to serve long prison sentences in Cuba for exercising freedom of expression. Amnesty International calls on the authorities to stop the harassment and intimidation of dissidents, release prisoners of conscience, amend repressive legislation, and enable greater exchange of information through the internet and other media.
