French Prime Minister Manuel Valls has blamed extremist groups for violent pro-Palestinian protests that took place last week in and near Paris.
A demonstration in the gritty northern Paris suburb of Sarcelles degenerated into violence Sunday with Jewish shops being looted and police using tear gas and rubber bullets against the crowd.
That rally, and another held a day earlier in Paris, had been banned but took place regardless. At Saturday's rally, dozens of protesters were arrested after clashes with police.
"A minority of radical forces are taking advantage of the situation," Valls told Le Parisien newspaper in remarks printed Monday, referring to the ongoing Israeli offensive in the Gaza Strip.
He said certain unspecified "networks and extremist groups are trying to capitalize on this by riding on sentiments of anti-Semitism and hatred" and using it "to foment disorder".
However, Valls also said the large majority of the demonstrators were spurred by "legitimate motives - to display their indignation at the atrocities of the war."
The self-defense operation has stirred up passions in France - home to the largest Muslim and Jewish communities in western Europe with around five million Muslims and half a million Jews.
Valls, who was a tough-talking interior minister until his promotion this year in a cabinet reshuffle, said he would not tolerate any violence.
"Public order... is a responsibility and the government assumes its responsibilities," he said.
"I will not give up on the unity of the country in favor of those who want to divide it. There are no Israelis or Palestinians in France, there are only French citizens."
Valls also said there was "great concern among Jews in France," when asked about a a comment by the head of the top Jewish body in France that there was a real fear of "pogroms".
He defended the go-ahead given to a pro-Palestinian rally in Paris scheduled on Wednesday, saying the parameters had been discussed with organizers who pledged to be "more responsible this time."
Protests in Paris on Saturday and Sunday resulted in extreme violence, as footage revealed Monday night, with rioters setting garbage cans on fire and clashing with riot police. The clashes resulted in a ban on further anti-Israel demonstrations last week.
Previous protests led to vandalism of several synagogues in the French capital city, with attacks on the Jewish community within; when police failed to arrive, dozens of Jewish youth mobilized to fight back.
Anti-Semitism has become so commonplace in France that the Israeli government launched a special mass Aliyah program for the French Jewish community; immigration to Israel from France has skyrocketed 312% in 2014.
