LONDON, CMC – The London-based human rights watchdog, Amnesty International, has called on Cuban authorities to “immediately and unconditionally” release five men named as prisoners of conscience. Amnesty International said the cases of the five men – Rafael Matos Montes de Oca, Emilio Planas Robert and the brothers Alexeis, Diango, and Vianco Vargas Martín – are “indicative of the continuing repression of freedom of expression on the island.” “These five cases are only the tip of the iceberg for Cuba’s repression of free speech,” said Javier Zúñiga, Special Advisor for Amnesty International.
