The two, members of the Internal Dissidents' Working Group for the Analysis of the Cuban Socio-Economic Situation, were arrested in July 1997 along with two other group members, Vladimiro Roca Antúnez and René Gómez Manzano, after issuing a critique of a document disseminated for the Fifth Congress of the Cuban Communist Party.

All four were sentenced in March 1999 to between three and a half and five years imprisonment on a charge of sedición, ‘sedition', under State Security legislation. Both Vladimiro Roca Antúnez and René Gómez Manzano remain imprisoned.

'The organisation will continue to press for the release of Vladimiro Roca Antúnez and René Gómez Manzano and for further measures to be taken that will ensure that the peaceful exercise of civil and political rights is not criminally sanctioned in Cuba,' Amnesty International said.

'At present dissidents - including journalists, political opponents and human rights defenders - continue to suffer severe harassment,' the organisation continued. Several hundred people, at least 25 of whom are currently identified by Amnesty International as being prisoners of conscience remain imprisoned for political offences.

The organisation has repeatedly sought the immediate and unconditional release of all those imprisoned for peacefully exercising their rights to freedom of expression, association and assembly.
