Former Cuban President Fidel Castro has died at age 90, his brother, President Raul Castro announced late Friday on state television.
No cause of death has yet been given for the leader of the 1950's Cuban Revolution.
Castro overthrew U.S-backed strongman Fulgencio Batista in 1959. He was fiercely opposed to the United States throughout the Cold War, and led the resistance against the U.S.-backed Bay of Pigs invasion ordered by President Kennedy in 1961.
The Cuban dictator's health began to decline in 2004, when he reportedly broke his knee and arm in a stumble. He turned over power to his brother Raul Castro shortly afterward.
Castro's death comes shortly after a thawing of relations between the United States and Cuba. President Obama has lifted multiple embargoes and travel bans to island since 2009.
