FILE - In this April 19, 2011 file photo, Fidel Castro, left, raises the hand of his brother President Raul Castro as they sing the international socialism anthem during the 6th Communist Party Congress in Havana, Cuba. For most of his life, Raul Castro played second-string to his brother, but for the past decade, it's Raul who's been the face of communist Cuba. On Friday, April 16, 2021, Raul Castro formally announced he'd step down as head of the Communist Party, leaving Cuba without a Castro in an official position of command for the first time in more than six decades.
