Paris police say 19 officers were injured and some 250 people detained after a protest against President Francois Hollande's leadership degenerated into violence.
Police said today that none of the injuries is critical.
The numbers of injured and detentions is high compared with other protests in recent weeks expressing discontent with Hollande, who is particularly unpopular for his handling of the economy.
Police say some 17,000 people took part in yesterday's largely peaceful protest, while organisers put the number several times higher.
Some 50 associations were involved, including conservative and far right groups.
Also present were supporters of provocateur-comic Dieudonne, who has been repeatedly convicted of anti-Semitism and racism.
