The demonstration in Milan remained peaceful, but there were brief clashes with police in both Rome and Turin.

Clashes erupted in Paris as a mass march drew to a close Saturday, with more than 400,000 people rallying across France over school funding and soaring living costs in a fresh challenge to President Emmanuel Macron. Police made nearly 1,000 arrests, the government said.

Paris returned to calm on Tuesday after its first quiet night since a weekend marred by France's most destructive rioting in years.

Curfews are in effect in parts of Paris and other French cities as authorities try to restore order following widespread rioting this weekend. Government officials have acknowledged "failures" in their handling of the unrest and say an investigation is underway to track down those responsible. Special correspondent Ross Cullen reports from Paris.

On Sunday evening, groups of people set fires to trash bins, bicycles and other objects in the streets and looted businesses in Paris, Lyon, Marseille and other cities, a day after major violence erupted Saturday during nationwide protests against rising living costs and poor conditions in schools.

"Those who looted will have to pay back for the damage, and those who sought to bring down the Republic will be held accountable," Macron said in a televised address to the nation.
