Fidel Castro launches memoirs

Former Cuban President Fidel Castro has made a rare public appearance to launch his memoirs.

The book, Guerrilla of Time, is almost 1,000 pages long and relates his childhood and rise to power in the Cuban Revolution.

Fidel Castro, 85, said it was every Cuban's duty to fight until the last moment, for Cuba, the planet, and humanity.

Sarah Rainsford who's in Havana says a lot can be gleaned from Fidel Castro's appearance.
