Fidel Castro has died at the age of 90.
The Communist revolutionary's death was announced on Cuban state television in the early hours of Saturday.
Castro stepped down as Cuba's president 10 years ago after suffering a severe gastrointestinal illness, and before his 90th birthday in August he told supporters he was going to die soon.
He led a coup in 1959 to overthrow the regime of the US-backed former Cuban president Fulgencio Batista, and remained hostile to Washington throughout his life.
Wearing green military fatigues and chomping on cigars for many of his years in power, Castro was famous for long, fist-pounding speeches filled with blistering rhetoric, often aimed at the United States.
At home, he swept away capitalism and won support for bringing schools and hospitals to the poor.
But he also created legions of enemies and critics, concentrated among Cuban exiles in Miami who fled his rule and saw him as a ruthless tyrant.
The bearded Fidel Castro took power in a 1959 revolution and ruled Cuba for 49 years with a mix of charisma and iron will, creating a one-party state and becoming a central figure in the Cold War.
He was demonised by the United States and its allies but admired by many leftists around the world, especially socialist revolutionaries in Latin America and Africa.
Transforming Cuba from a playground for rich Americans into a symbol of resistance to Washington, Castro outlasted nine U.S. presidents in power.
He fended off a CIA-backed invasion at the Bay of Pigs in 1961 as well as countless assassination attempts.
President Raul Castro announced the news on state TV early on Saturday morning.
