HAVANA (AFP) - Cuban artists, media, youths and even transgender activists paid tribute Saturday to revolutionary icon Fidel Castro as he turned 85. "Cuba and Latin America sing the praises of Fidel" and "Latin America gives us its heart," national newspapers Granma and Juventud Rebelde said in their headlines as cultural galas got in full swing, along with voluntary blood donations and book presentations. The communist island nation has been partying since Tuesday, with concerts, ballet performances and art exhibitions organized on behalf of the man who led Cuba for nearly 50 years before handing the reins of power to his brother Raul.
