MIAMI (AP) - Fidel Castro's younger sister says she began collaborating with the CIA shortly after the United States' failed Bay of Pigs invasion of Cuba in 1961.
Juanita Castro initially supported her brother's 1959 overthrow of the Batista dictatorship, but quickly grew disillusioned.
In a memoir released Monday by Santillana USA, the 76-year-old says the wife of the Brazilian ambassador to Cuba persuaded her to meet a CIA agent during a trip to Mexico City.
Castro says in the book she agreed then to help the CIA gather information, but refused to accept money for it.
Her home became a sanctuary for anti-communists before she fled the island in 1964. She eventually settled into a quiet life in Miami and ran a pharmacy until 2007.
