Fidel Castro went back on TV and accused the USA for fueling nuclear tensions. The ‘Lider Maximo’, who handed over the Presidency of Cuba to his brother Raul in 2006 for health problems, claimed that it was the United States and not Pyongyang that sank the South Korean gunboat ‘Cheonan’ at the end of March with the aim of triggering a conflict between the two Koreas.
