The eldest son of the late Cuban revolutionary leader Fidel Castro committed suicide on Thursday, state media reported. He was 68 years old. Cuba’s official newspaper Granma said Fidel Castro Diaz-Balart (pictured) was undergoing treatment for depression for some time and took his life on Thursday morning. ‘Fidelito’ (Little Fidel) — as he was known on the Caribbean island nation for his close resemblance to his father — was very popular among Cubans although he never held a political position. Many still remember him as a little boy dressed in an olive drab military uniform, accompanying his father on January 8, 1959 as he entered Havana triumphantly after the revolution. He followed his father’s communist ideals and was working as vice-president of the Cuban Academy of Scientists before his death. His mother, Mirta Diaz-Balart, a Cuban aristocrat, was briefly married to Fidel Castro before the revolutionary took control of the small Caribbean island and allied his government with the Soviet Union during the Cold War.
