HAVANA (Reuters) - Fidel Castro's absence from the 50th anniversary of the Cuban revolution and a prolonged halt to his output of newspaper columns have raised concerns that the health of the 82-year-old former leader may be declining.
The Cuban government has said nothing about his condition, but Venezuelan President Hugo Chavez, a close Castro ally, appeared to signal a problem when he spoke about him in elegiac terms on Sunday on his weekly radio and television show.
