Watch: Why is the US going after Cuba's Raúl Castro 30 years on?

BBC correspondent Will Grant reports from Havana, hours after the US charged former Cuban leader Raúl Castro with conspiracy to kill US nationals and other crimes.

The case unveiled on Wednesday accuses Castro and five others over the 1996 downing of two planes belonging to Cuban-American group Brothers to the Rescue. Four people were killed, including three Americans.

Cuban President Miguel Díaz-Canel has called the charges "a political manoeuvre, devoid of any legal foundation".

Nearly 95 years old, Castro, the brother of late Cuban leader Fidel Castro, remains an influential figure, acknowledged on the island as the surviving "leader of the Cuban Revolution".
