Police and anti-fascist demonstrators clash in Athens on the sidelines of a large protest of some 15,000 people, after a court branded Greece's neo-Nazi party Golden Dawn a criminal organisation. The prosecutions were sparked by the late-night murder of 34-year-old anti-fascist rapper Pavlos Fyssas in September 2013. He was chased down by a mob of Golden Dawn thugs and stabbed to death in front of a cafe in the western Athens suburb of Keratsini. The killer, former truck driver Yiorgos Roupakias, confessed, but the attack sparked outrage and the charges that Golden Dawn was a paramilitary-style organisation that used beatings, intimidation and murder as tactics -- all with the knowledge of senior party members.
