VERACRUZ, Mexico—Organizers of a Carnival festival in the Mexican port city of Veracruz say 15 Cuban musicians and dancers have gone missing after marching in the city's annual parade.

Festival President Anselmo Estandia said Saturday that the missing Cubans were part of a 93-person committee that arrived in Veracruz on Feb. 8.

Estandia says that the Cubans missed their flight home Wednesday and that their disappearance is considered a possible defection.
