Anti-Castro demonstrators are staging a protest outside a concert venue in Miami, Florida, where the Cuban salsa band, Los Van Van, are to play.

The protestors say the performance should not go ahead because it is an advertisement for the communist way of life.

The concert organisers had to invoke the Constitutional right to expression to avoid cancellation.

Police in Miami have cordonned off a large area around the auditorium so that the concert-goers are not intimidated.

Correspondents say that on several previous occasions, anti-Castro protestors have prevented Cuban concerts from taking place in Miami.
