Confirmed by Cuban State Media.
From The Washington Post:
Fidel Castro, whose Cuban revolution turned his Caribbean island into a potent symbol of the world’s greatest ideological and economic divides of the 20th century, has died, Cuban state media announced early Saturday. He was 90.
The death was announced on Cuban state TV by Castro’s younger brother, Raul, who succeeded his brother years ago as the country’s leader.
