The leaders of two fringe neo-fascist groups in Italy have been jailed for more than eight years for their role in violent demonstrations in Rome's city centre two years ago. Roberto Fiore, the 64-year-old leader of Forza Nuova, was jailed for eight years and six months by a Rome court on Wednesday. Giuliano Castellino, a former Rome leader of Forza Nuova who last year created his own political movement, Italia Libera, was sentenced to eight years and seven months.
