(ANSA-AFP) - ATHENS, MAR 11 - A Greek appeals court on Wednesday handed 13-year prison terms to leading members of the neo-Nazi Golden Dawn party in a landmark case over crimes committed at the height of the country's economic crisis. The court last week had already found several officials, including its founder-leader Nikos Michaloliakos, guilty of "running a criminal organisation". Michaloliakos and five other officials were sentenced to 13-year jail terms but the 68-year-old leader will remain free on health grounds. About 30 other party officials were jailed for up to 10 years. Crimes attributed to the group include the savage beating of Egyptian fishermen in 2012 and the murder of anti-fascist rapper Pavlos Fyssas in 2013. Golden Dawn leaders have always denied involvement in the attacks, which were carried out by the group's so-called "assault squads". But in closing arguments, prosecutor Kyriaki Stefanatou in December said Michaloliakos had "complete control and knowledge of what was happening". She called the paramilitary-style group a "true child of Nazi ideology". (ANSA-AFP).
