As tens of thousands rallied globally in solidarity with the Palestinians, Germany and France prohibited all such protests, a democratic right, within their borders.
Home to the European Union's largest Jewish and Muslim communities, the two countries have cracked down on pro-Palestinian groups since the conflict between Israel and Palestine started on Oct. 7.
The governments say the curbs are to stop public disorder and prevent anti-Semitism.
But supporters of the Palestinians say they feel blocked from publicly expressing support or concern for people in the Gaza Strip without risking arrest, their jobs or immigration status.
Nearly 3,800 people have been killed, including children, in Gaza since Israel launched a campaign of bombing following a surprise attack by the Palestinian resistance group Hamas. More than 1,400 Israelis have died.
Israel's blockade of Gaza prevents food, fuel and medicine from getting in, creating a humanitarian crisis.
"We are scared, we are worried about being accused of justifying terrorism, when we just want to support a humanitarian cause," said Messika Medjoub a 20-year-old Algerian French history student.
She was speaking at a banned protest in Paris last Thursday, which police broke up with tear gas and water cannon.
French Interior Minister Gerald Darmanin clamped a nationwide ban on pro-Palestinian protests last week, citing the risk of public disorder. Nine have been banned in Paris since Oct.7.
Over the weekend, Paris police issued a ban on the "presence and circulation of people that present themselves as pro-Palestinian." Since Oct. 12 they have issued 752 fines and arrested 43 people.
In Germany, Berlin police have approved two requests for pro-Palestine protests, a police spokesperson said. Both were proposed as silent vigils.
But at least seven, including one called Jewish Berliners Against Middle Eastern Violence and another entitled Youth Against Racism, were refused permission. At least 190 people have been detained at protests.
The French and German governments say they need to protect Jewish communities citing a rise in anti-Semitic violence since the conflict began.
In Germany, the issue is particularly acute because of the killing of 6 million European Jews in the Holocaust by the Nazis.
"Our history, our responsibility for the Holocaust makes it our duty in every moment to stand for the existence and security of Israel," Chancellor Olaf Scholz told legislators last week.
Darmanin suggested on Tuesday that 327 anti-Semitic acts had taken place in France since Oct. 7.
Human rights groups say Jewish communities must be protected but they are concerned legitimate protest is being repressed.
"Human rights law doesn't allow the government to just broadly say there is a concern about violence and use that as a justification to ban protests," said Benjamin Ward, a deputy director at Human Rights Watch.
"The question is whether it's proportionate – and that's where I think there is a concern."
Hungary and Austria have also blocked pro-Palestine protests since Oct.7, while in the rest of Europe, large rallies supporting Palestinians have been held with few restrictions.
Historic responsibility
With an estimated 30,000 Palestinians, Berlin has one of the largest diaspora communities outside the Middle East, and anxiety over what is happening in Gaza is running high.
At an unauthorized protest in Berlin last week, Palestinians who spoke to Reuters said they felt nervous about speaking out, fearful of being labeled pro-Hamas in a country where supporting Israel is sacrosanct.
"I feel that in Germany we're not allowed to speak our mind," said Saleh Said, standing on the fringes of an unauthorized gathering.
The 32-year-old German born to Palestinian parents, said he condemned Hamas's violence.
Berlin's education authorities last week told schools they could ban students from wearing the Palestinian Kufiya scarf and "free Palestine" stickers.
Post-World War II German governments have pursued close ties with Israel because of the Holocaust.
Felix Klein, Germany's ombudsman in charge of fighting anti-Semitism, said the country's history meant it had to be especially vigilant.
Even before the Hamas attack on Israel, Germany was restricting pro-Palestinian demonstrations, with Berlin authorities banning several on public safety grounds.
But, Amnesty International said in September that German police's justifications for bans on pro-Palestinian groups appeared to be based on "stigmatizing and discriminatory stereotypes," citing references in police orders to people "from the Arab diaspora, in particular with Palestinian background."
France cracks down
In France, pro-Palestinian groups were also facing curbs prior to the attacks.
An attempt last year to ban two organizations – Collectif Palestine Vaincra and Comite Action Palestine – was overruled by a higher court that said their "bold, even virulent" positions did not constitute hate speech or terrorism.
Interior Minister Darmanin announced that he had initiated judicial proceedings for "anti-Semitism, apologia for terrorism and support for Hamas" against 11 organizations, including Collectif Palestine Vaincra and Comite Action Palestine. Both deny the allegations.
On Wednesday, in response to an appeal against Darmanin's instructions, a court said local authorities should ban protests on a case-by-case basis.
People who spoke to Reuters at a banned protest in Paris last Thursday said the government's move to prevent gatherings for Palestinians was unfair but unsurprising.
"The government is indulgent when it comes to Israel's crimes. They are being biased and they are showing it," said Hortense La Chance, a 32-year-old cook.
