He was 68 years old. "Fidel Castro Diaz-Balart, who had been treated by a group of doctors for several months due to deep depression, took his life this morning," Cuba's official newspaper Granma reported. "Fidelito" -- as he was known on island nation -- had initially been hospitalized for his condition and then continued with outpatient follow-ups. Born on September 1, 1949, he was the son of the revolutionary Castro's first marriage to Mirta Diaz-Balart. A scientist who trained in the former Soviet Union, Fidel Jr helped usher in the development of a nuclear power program in the Communist-ruled country. At the time of his death he had served as a scientific adviser to the Cuban government and was vice president of the country's Academy of Sciences. Funeral arrangements will be made by the family, state media said.
