WASHINGTON (Sinclair Broadcast Group) -- The late Fidel Castro's 68-year-old son has been found dead after reportedly committing suicide.
Official website Cubadebate says Fidel Castro Diaz-Balart took his life Thursday after months of treatment for a "deeply depressed state."
"Diaz-Balart, who had been attended by a group of doctors for several months due to a state of profound depression, committed suicide this morning," a Cuban state run website said according to The Daily Mail.
The eldest son of Cuba's former leader was known for his distinctive beard and resemblance to his father. He had nicknames such as Fidelito, Little Fidel and Fidel Jr. because of the resemblance.
A brief note read on state television said that his treatment had "required a hospitalization regime then outpatient follow-up."
Castro Diaz-Balart studied nuclear physics in the former Soviet Union and served as scientific adviser to Cuba's Council of State. He was vice president of the Cuban Academy of Sciences. He previously led its nuclear program.
Castro Diaz-Balart's mother was Mirta Diaz-Balart, a woman from Cuba's aristocracy who Castro married in his youth before beginning the revolutionary struggle that later brought him and his brother Raul to power.
Because of his maternal lineage, Castro Diaz-Balart is cousin to Republican Congressman Mario Diaz-Balart, who represents Cuban exiles in Florida.
Fidel Castro ruled over Cuba through 10 U.S. presidents. He passed away in 2016 at the age of 90.
