While the vast march in the centre of the Algerian capital was largely calm, tensions were noticeably higher than at previous rallies, and clashes erupted between the young protestors and police towards the end of the protest, France24 reports.
Several protestors were slightly hurt, injured by stones or in the ensuing scuffles, or suffered the effects of tear gas.
The police said 83 of its personnel were wounded, including four seriously hurt.
It put the violence down to “delinquents” infiltrating the crowds, and said 108 people had been arrested.
Other protestors stepped in to calm the tensions, with some kneeling in the streets, raising their hands in peace.
