In 2013, at least four journalists were convicted of libel in Italy, one of the few European Union states where defamation is still a criminal offense. In May, a Milan magistrate found three journalists guilty of libel and sentenced them to prison. In a separate case, a 79-year-old editor was sentenced to house arrest in October in connection with at least eight libel convictions against him between 2007 and 2012. The convictions were related to his articles and commentaries on public life in Italy, focusing on public figures involved in corruption cases. The independent newspaper La Stampa was attacked twice with explosive devices. Journalists continued to face threats and physical attacks from extremists and organized crime. According to OSSIGENO per l'Informazione, a local press freedom watchdog, scores of journalists received threats from unidentified persons throughout the year; several of them lived under police protection as a result.
