Castro, 68, also known as "Fidelito" because of how much he looked like his father, had initially been hospitalized for depression and then continued treatment outside of hospital.

A nuclear physicist who studied in the former Soviet Union, he had been working as a scientific counselor to the Cuban Council of State and Vice-president of the Cuban Academy of Sciences at the time of his death.

His father, who built a communist state on the doorstep of the United States during the Cold War, died just over a year ago, on Nov. 26, 2016, aged 90.
