Police fire tear gas at May Day protesters
Police have fired tear gas at protesters on the sidelines of a May Day workers' march in Paris.
Scores of hooded youths threw Molotov cocktails at security forces who fired back with tear gas during the march on Monday.
The annual march to celebrate workers' rights this year included calls to block far-right presidential candidate Marine Le Pen from winning the presidency during a run-off election on Sunday.
Video showed riot police surrounding the protesters disrupting the march after isolating most of them from the rest of the crowd near the Place de la Bastille. However, some continued to lob firebombs that exploded into flames in the street.
It was not immediately clear if anyone was injured in the incidents.
