French police are guarding the homes of leading MPs as fears grow of antisemitic violence triggered by Israel's war with Hamas.
Police have said they are protecting National Assembly President Yaël Braun-Pivet and MP Meyer Habib.
France's interior minister said 100 antisemitic acts had been recorded since Saturday.
In a separate move, Germany's chancellor declared "zero tolerance" for antisemitism.
He told parliament a pro-Palestinian group that had celebrated the murders of Israeli civilians on Saturday would be banned.
French
President Emmanuel Macron was due to meet political leaders and give a
TV address in a bid to prevent the war from escalating tensions.
France has a Jewish community of almost 500,000, the biggest in Europe.
Interior
Minister Gérald Darmanin told France Inter radio on Thursday that "more
than 100" anti-Jewish incidents had been recorded since hostilities
broke out.
Most
involved graffiti showing "swastikas, 'death to Jews,' calls to
intifadas against Israel". However, some incidents included people being
arrested attempting to carry knives into schools and synagogues, he
added.
It has also emerged that Assembly President Yaël Braun-Pivet has received death threats.
A
member of President Emmanuel Macron's Renaissance party, she had
parliament lit this week in the colours of the Israeli flag in response
to the Hamas attack on Israel and called a minute's silence before an
Assembly session on Tuesday.
Ms
Braun-Pivet also announced that Maryam Abu Daqqa, a member of the
Popular Front for the Liberation of Palestine (PFLP), would be banned
from attending a documentary screening in parliament next month. The
militant organisation is recognised as a terrorist organisation by the
EU.
Meyer
Habib has also been given protection. He represents a constituency for
overseas French citizens which includes Israel and the Palestinian
Territories and is a vocal supporter of Israel. After the Hamas attack
he said "we are witnessing the return of pogroms".
French politics has been riven by the Hamas attack and its aftermath.
While
most parties have condemned Saturday's "terrorist attack" and expressed
support for Israel's right to respond, the initial response from
Jean-Luc Mélenchon's far-left La France Insoumise (France Unbowed) party
was more equivocal.
A
statement by the party referred to the Hamas attack as "an armed
offensive of Palestinian forces", prompting fierce criticism from other
parties, including left-wing allies such as the Socialist and Communist
parties.
In Germany, Chancellor Olaf Scholz told MPs in the Bundestag that Israel's security was German state policy.
He
announced that Samidoun, a pro-Palestinian group pictured handing out
sweets in the Neukölln area of Berlin to celebrate the Hamas attack,
would be banned. "We do not tolerate antisemitism," he added.
According
to German authorities, in several towns across the country including
Mainz, Braunschweig and Heilbronn, Israeli flags raised in solidarity
with the country were torn down and destroyed, sometimes in just a few
hours.
"The act disrespects and mocks the victims" of Hamas's attack, Braunschweig's mayor, Thorsten Kornblum, said.
Mr Scholz added that "without Iranian support, Hamas would not have been able to carry out these unprecedented attacks".
