On October 4, the U.S. State Department issued a protest of the Cuban government’s detention of Tómas Nuńez Magdariaga, a democratic activist.
The U.S. said that he “had been on a hunger strike for more than 50 days in protest against his wrongful imprisonment,” that “his health is in a critical state, and that the authorities have denied his family the opportunity to see him.”
The statement added that Nuńez was “a member of Cuba’s largest opposition group, the Patriotic Union of Cuba, on false charges and convicted him in a sham trial, during which they denied him the opportunity to present witnesses in his favor.”
As a result, the U.S. condemned these practices “in the strongest terms, and calls on the Cuban government to release Mr. Nunez, whose life hangs in the balance, and all political prisoners in Cuba.”
Similar protests were made by the Secretary-General of the Organization of American States (OAS), Senator Marco Rubio and the non-governmental Cuban Commission for Human Rights and National Reconciliation. The Commission added that there were at least 224 arbitrary short-term detentions for political reasons. 
Apparently a critical prosecution witness against Nunez was Aldo Rosales Montoya. However, Rosales recently submitted an affidavit to the court that his trial testimony was false and done on instructions from Cuba’s State Security. As a result, Rosales has been accused of perjury.
