Renewed clashes broke out in Paris on Saturday between police and members of the Kurdish community angry at the killing on Friday of three members of their community,
France 24 reports.
Several cars were overturned and small fires set alight near Republic Square, the traditional venue for demonstrations in the city where Kurds earlier held a peaceful protest.
Clashes broke out as some demonstrators left the square, throwing projectiles at police who responded with tear gas.
A gunman carried out the killings at a Kurdish cultural centre and nearby cafe on Friday in a busy part of Paris' 10th district, stunning a community preparing to commemorate the 10th anniversary of the unresolved murder of three activists.
Police arrested a 69-year-old man who the authorities said had recently been freed from detention while awaiting trial for a sabre attack on a migrant camp in Paris a year ago.
Following questioning of the suspect, investigators had added a suspected racist motive to initial accusations of murder and violence with weapons, the prosecutor's office said on Saturday.
After an angry crowd clashed with police on Friday afternoon, the Kurdish democratic council in France (CDK-F) organised a gathering on Saturday at Republic Square.
Hundreds of Kurdish protesters, joined by politicians including the mayor of the central 10th district, waved flags and listened to tributes to the victims.
