Cuba's Communist government freed dissident writer Raul Rivero from prison today, the latest in a series of releases.
Rivero was released a day after Cuba unexpectedly freed three dissidents who had been jailed last year in a broad crackdown.
Those freed on parole Monday included economics writer Oscar Espinosa Chepe, who was hospitalized behind bars for months with a liver ailment.
Also freed Monday for health reasons were dissidents Marcelo Lopez and Margarito Broche. Lopez has a neurological disorder, and Broche suffered a heart attack behind bars in August.
International human rights groups called on Fidel Castro's government to free dozens of others still behind bars.
The latest releases bring to 11 the number of dissidents in the original group of 75 who have since been freed after being sentenced to prison terms ranging from six to 28 years in April 2003.
They were charged with working with the U.S. government to undermine Castro's socialist system, something the dissidents and American officials denied.
