Fidel Castro, the communist revolutionary who has controlled Cuba since 1959, died Friday at age 90.

His brother Raul, to whom the dictator handed the reins of power in 2008, announced the news in a televised address.

"At 10:29 at night, the chief commander of the Cuban revolution, Fidel Castro Ruz, died," he said, according to Reuters.

"Ever onward, to victory," he said, using the slogan of the Cuban revolution. Castro, 85, did not give the cause of his brother's death.

Cubans exiled to the United States by Castro's totalitarian regime celebrated in the streets in Miami, Fla., in other Cuban communities and on social media. Castro's rule had been marked by killings and jailings of opponents, including journalists, in addition to other human rights abuses. 

Indian Prime Minister Narendra Modi and Venezuela's socialist President Nicolas Maduro, who said "revolutionaries of the world must follow his legacy," issued tributes to the former leader, Reuters reported.

Cuban citizens who had businesses and property taken by Castro's regime expressed relief that the chains of oppression are nearly broken but still see Raul Castro's rule as another obstacle to overcome.

Since taking control of the Caribbean island nation, Raul Castro has changed Cuba by beginning to open markets, making economic reforms and re-opening diplomatic ties with the United States in December 2014 after decades of animosity.
