Paris student dead after skinhead attack
A French left-wing activist has died after an attack blamed on skinheads in central Paris.
Clement Meric, an 18-year-old student, was with friends when he was "hit extremely violently" by several men during a fight, officials say.
Several people with links to the far-right have been arrested, according to French media.
French President Francois Hollande said he condemned Wednesday night's attack "in the strongest terms".
Mr Meric - a student at Sciences Po, a leading undergraduate school in Paris - was in a busy shopping district near St Lazare train station when three men described as skinheads and a woman confronted his group.
He was struck by a knuckle-duster and his head hit the ground as he fell, police say.
The teenager was placed on life support but was declared brain dead and died on Thursday.
Left-wing parties have called for a demonstration in Paris later on Thursday.
They have blamed the attack on a fringe far-right group, the Revolutionary Nationalist Youths. However it denied any involvement.
The main far-right party, the National Front, described the incident as "appalling".
Correspondents say it has re-ignited a public debate over the role of small right-wing groups in recent violent protests against gay marriage in France.
A friend of Mr Meric's, Claire Cosquer, told reporters that his death was murder and had happened in the context of "a very worrying rise of radical far-right movements".
