Angel, Cesar and Marcos Ramirez Castellano have already defied the odds by their very existence, as they are a rare set of identical triplets.

But the three 13-year-olds are extraordinary in another way - they are all top young ballet dancers who made it into the elite feeder school for Cuba's prestigious National Ballet.

Their teachers say that all three of them have the talent to forge successful careers in ballet, following in the footsteps of Cuban dance stars like Carlos Acosta.

Sarah Rainsford went to meet the triplets during one of their hectic days at school.
