breaking now... according to the government-run Granma newspaper.
(CNN) -- Fidel Castro announced his resignation as president of Cuba and commander-in-chief of Cuba's military on Tuesday, according to a letter published in the state-run newspaper, Granma.
Castro, 81, temporarily handed power to his younger brother Raul Castro in July 2006 after undergoing intestinal surgery. He hasn't been seen in public since his surgery, but he has appeared in numerous videos and photos in state media.
In December 2007, a Cuban television news anchor read a letter reportedly written by Fidel Castro promising he would not "cling to office" or be an impediment to rising young leaders.
Castro took power in Cuba in 1959 and has ruled the island nation ever since, governing the first communist nation in the Western Hemisphere.
