The US has charged former Cuban leader Raul Castro with conspiracy to kill US nationals and other crimes over the 1996 downing of two planes between Cuba and Florida, BBC reported. 

The case unveiled on Wednesday accuses Castro and five others in the shooting down of the aircraft belonging to Cuban-American group Brothers to the Rescue and killing four people, including three Americans.

Castro, now 94, was then head of the country's armed forces and faced international condemnation over the crash.
