AUTHORITIES at Madrid's airport have found the body of a Cuban man in the undercarriage of a plane that arrived from Havana.

The man "probably died from being crushed" after apparently hiding in the rear landing gear of the Iberia flight before it left Cuba, but an autopsy would determine the exact cause of death, police said.

Spanish media identified the man as Adonis GB, 23, and said he had injuries to his head and chest.
