FILE– Fidel Castro, Jr., is shown as he waves a small flag while he rides on a tank in Havana in this, Jan. 7, 1959 file photo. If Fidel Castro seems to be taking the case of 6-year-old Elian Gonzalez personally, it may be because he was party himself to a custody battle involving his first-born son more than four decades ago. Others seen in photo are unidentified. (AP Photo)
