The first son of Cuba’s former President, Fidel Castro has killed himself in Havana.

Fidel Ángel Castro Díaz-Balart, 68, was found dead on Thursday morning and is said to have suffered from depression.

It is unclear at this time how he committed suicide.

The nuclear scientist, also known as "Fidelito," or Little Fidel, because of how much he looked like his father, had initially been hospitalized and then continued treatment as an outpatient.

Fidelito had been working for his uncle President Raul Castro 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.

Fidelito's death came just over a year after that of his father on Nov. 25, 2016, aged 90.
