Melba Hernandez, known as the heroine of the Cuban Revolution, has died aged 92.
She was one of two women who helped Fidel Castro launch his revolutionary assault in 1953.
A Communist Party statement released on Monday said she died of complications resulting from diabetes:
“She is one of the most glorious and beloved combatants of the revolutionary quest, (and an) imperishable example of the Cuban woman,” it read.
Hernandez was sometimes seen at official events with one of the Castro brothers in her later years. Fidel stepped down due to ill health in 2006, passing command to his younger brother Raul.
