Clashes broke out between dozens of demonstrators and police in Paris on the 23rd Saturday of yellow-vest protests after authorities warned that rioters could return to the French capital to spark a new wave of violence.

Dozens of black-hooded demonstrators threw rocks at police and some set fire to motor-cycles in the center of French capital, according to Reuters TV footage. Trash cans and a several scooters were also set ablaze.

Police responded by firing tear gas and stun grenades. Some officers also marched toward demonstrators to control the crowd and funnel it to Paris’ Place de la Republique, where they were authorized to demonstrate.

As of 1300 GMT, 110 people had been arrested and placed in custody, the Paris prosecutor’s office said.

Several demonstrators clearly alluded to the catastrophic fire at Notre-Dame cathedral on Monday, which prompted an outpouring of national sorrow and a rush by rich families and corporations to pledge around 1 billion euros ($1.12 billion) for its reconstruction.

“Millions for Notre-Dame, what about for us, the poor?” read a sign worn by a demonstrator. “Everything for Notre-Dame, nothing for the miserables,” read another sign that evoked Victor Hugo’s well-known novel.

The city was on high alert after Christophe Castaner, the interior minister, said domestic intelligence services had informed him of a potential return of rioters intent on wreaking havoc in Paris, Toulouse, Montpellier and Bordeaux, in a repeat of violent protests on March 16.

Large portions of the Paris metro network were closed and about 60,000 police were deployed across France, authorities said. (Reuters)
