AlQa'dah 13, 1434, Sep 19, 2013, SPA -- Greece's government moved Thursday to crack down on the ultranationalist Golden Dawn party after the fatal stabbing of an anti-fascist rapper, as Europe's top human rights official warned in an interview that Greece was the most worrying example of a wider European drift toward radicalization. The death of 34-year-old Pavlos Fyssas early Wednesday shocked the country and led to widespread condemnation from across the Greek political spectrum and abroad. The man arrested for stabbing Fyssas admitted to the killing to police and identified himself as a member of Golden Dawn. The party's supporters have a reputation for increasingly virulent intimidation and violent attacks, usually against dark-skinned migrants. Golden Dawn itself insists it had nothing to do with the death, and has condemned the attack. Public Order Minister Nikos Dendias said Golden Dawn members were jeopardizing the country's security."This activity goes beyond the limits of isolated incidents, is an affront to public sentiment, undermines the authority of law, insults human rights and human dignity, jeopardizes public order and the country's internal security," he said.
