PARIS (Reuters) - Minor scuffles broke out between about 60 to 80 anti-National Front protesters and police near the Zenith concert hall in north-east Paris ahead of a rally by far-right leader Marine Le Pen, a Reuters photographer saw.
Police fired teargas at the protesters, some of whom threw chunks of wood.
French voters go to the polls on Sunday in the first round of the most unpredictable presidential election in decades.
Opinion polls have for months shown Le Pen and centrist Emmanuel Macron qualifying for the May 7 run-off, but the gap with conservative Francois Fillon and far-leftist Jean-Luc Melenchon has been tightening.
