Demonstrators raise their fists on June 6, 2013 during a demonstration at Place Saint-Michel in central Paris, after a young far-left activist was killed during a fight with skinheads in central Paris. Clement Meric, an 18-year-old French far-left activist and student at the city's prestigious Sciences-Po university, died on June 6 following the fight, a police source said. Clement Meric had been left brain dead after the violence on June 5. The police source said three men and one woman had been held and that the attacker who is thought to have dealt the fatal blow denied having an intention to kill. TOPSHOTS/AFP PHOTO / PIERRE ANDRIEU
