The pope, who met Fidel Castro when he visited Cuba last year, said he had received the "sad news" and added: "I express to you my sentiments of grief."

Fidel Castro, who was a professed atheist, was baptised as a Catholic and educated in schools run by the Jesuits, the religious order of which the pope is a member.
