During the Gaza war, there has been an observed increase in antisemitic incidents worldwide. In the United States, organizations opposed to antisemitism, including Anti-Defamation League and the American Jewish Committee, reported that the total incidence of antisemitic occurrences increased significantly. Organizations in Western European countries, such as the UK's Community Security Trust and France's Service de Protection de la Communauté Juive (SPCJ), reported similar increases. There have been widely reported individual acts of violence against Jews around the world since the Gaza war began. Among the most significant events were the 2023 antisemitic riots in the North Caucasus, the 2024 Dagestan attacks, the fatal 2025 Manchester synagogue attack, the 2025 Bondi Beach shooting and the 2026 London antisemitic attacks, including the 2026 Golders Green attack.

The distinction between antisemitism—hostility, prejudice, or discrimination against Jews—and anti-Zionism—opposition to Zionism—has been disputed. Israeli leaders and supporters of Israel have frequently accused their perceived opponents of antisemitism. Critics of these characterizations—including scholars, journalists, and activists—have described them as exploiting the accusation of antisemitism to silence criticism of Israel. The line between the two categories is hard to define, as there can be significant overlap between them.Jeffrey Herf The Three Faces of Antisemitism: Right, Left and Islamist (Routledge, 2024), 286 pp. (hardback).David Hirsh, ed.

International Accusations that Israel is committing genocide in the Gaza strip have increased since the war began, with human rights organizations Amnesty International and Human Rights Watch both accusing Israel of genocide in late 2024. Some commentators have said that such accusations can be antisemitic. The novelist and historian of antisemitism Dara Horn said that there has been a proliferation of "fact-resistant slogans that demonize Jews" since October 7 across America, offering the example of "Genocide supporters!". Horn called these accusations "recycled from medieval blood libels and KGB talking points". Genocide accusations have been criticized in strong terms as a kind of "blood libel".

Among the anti-Israel incidents which Israel or its supporters have accused of antisemitism are the Gaza war protests, South Africa's genocide case against Israel at the International Court of Justice, and Greta Thunberg's participation in attempts to break Israel's blockade on the Gaza Strip.

Asia Armenia On 15 November 2023, unknown assailants set fire to the Mordechai Navi Synagogue in Yerevan and disseminated the arson attack on social media.

China

After the war began, the Associated Press noted a rise in antisemitism on Chinese social media sites, substantive enough that the Israeli embassy in Beijing had to filter comments on its social media account. An employee of the Israeli embassy in Beijing was stabbed and injured by a foreign man on 13 October 2023.

Antisemitic reactions to the war have been widespread on Chinese social media. Antisemitic comments were not removed from Chinese social media sites, suggesting that the state is comfortable with these kinds of remarks, according to Eric Liu, an editor of China Digital Times.

Turkey

In October 2023, Turkish Jewish newspaper Şalom reported rising cases of antisemitism and reported hate speech on Twitter and social media. In one example, a second-hand book store in a tourist area put up a sign saying "No Jews allowed".

United Arab Emirates In November 2024, Chabad rabbi Zvi Kogan was found murdered in Al Ain, UAE. Emirati officials said he was abducted by three Uzbek nationals who fled to Turkey, where authorities apprehended and extradited them to the UAE.

Vietnam In June 2024, a family of Jewish social media influencers, the Namdars, posted a video apparently showing them subjected to antisemitic insults by the owner of a restaurant in Hanoi, Vietnam.

Europe

Austria

On 1 November 2023, unidentified vandals set a fire and sprayed swastikas on external walls overnight in the Jewish section of the Vienna Central Cemetery. The entrance lobby to a ceremonial hall was burned for the first time since the 1938 Kristallnacht pogrom by the Nazis, but there were no injuries. The attack was condemned by Austrian Chancellor Karl Nehammer.

A periodic survey among 8,000 Jews in 13 EU member states, published on 11 July 2024 by the European Union Agency for Fundamental Rights, indicated that 38% of the 363 Austrian respondents had experienced antisemitic harassment in the year before the survey. In addition, 62% of those polled encountered online antisemitism all the time in the year leading up to the survey, and 18% said that antisemitism they encountered had negatively affected their mental health.

Belgium

On 22 November 2023, at least 85 gravestones were damaged and many Stars of David were stolen from a cemetery in Charleroi. Only the cemetery's Jewish section was vandalized. On 19 December, swastikas and Stars of David were graffitied on gravestones in a Jewish cemetery in Kraainem.

In August 2024, Belgian author Herman Brusselmans wrote a column in Humo, a humor magazine, stating that when he saw images of a Palestinian child crying for his dead mother, he imagined it was his own son and friend suffering in Gaza, leading him to "get so angry that I want to ram a sharp knife through the throat of every Jew I meet." In response to backlash against the column, the magazine stated that Brusselmans was a satirist whose work should not be taken literally and removed the column. Brusselmans was charged with antisemitism and incitement to hatred. He was acquitted in March 2025.

Cyprus Israel confirmed the Mossad helped local authorities foil a terror plot against Israeli and Jewish people in Cyprus on 10 December 2023. Netanyahu's office accused the Iranian government of being behind the plot, and said on behalf of the Mossad that Israel was "troubled" by Iranian use of Turkish-controlled Northern Cyprus for both terrorism and as an "operational and transit area".

Czech Republic In August 2024, the Federation of Jewish Communities in the Czech Republic reported 4,328 antisemitic incidents in the country in 2023, an increase of 90% from the previous year.

In February 2024, Denmark's Jewish community reported a record high of 121 antisemitic incidents in the country in 2023, 101 since the October 7 attacks.

France

In response to a rise in antisemitic incidents, the French Interior Minister Gerald Darmanin ordered a ban on pro-Palestinian demonstrations in the country in a letter sent to regional police authorities on 12 October 2023. In a televised address later that day, French President Emmanuel Macron warned, "Let's remember that antisemitism has always been the precursor to other forms of hate: one day against the Jews, the next against the Christians, then the Muslims, and then all those who are still the target of hate due to their culture, origin or gender." On October 18, the Conseil d'État rejected an appeal by a pro-Palestinian organization asking for the suspension of Darmanin's instruction, but stated that only local authorities should review individual cases for security risks. According to the ruling, Darmanin later clarified that he only referred to protests publicly celebrating the October 7 attacks.

On 31 October 2023, Stars of David were painted in multiple spots across several building fronts in a southern district of Paris. Similar tags appeared over the weekend in suburbs of the city, including Vanves, Fontenay-aux-Roses and Aubervilliers.

On 4 November 2023, a Jewish woman was stabbed in Lyon and a swastika was graffitied on her home.

A report released in late January 2024, approximately 3.5 months post the October 7 attack, documented a significant uptick in antisemitic acts within France. The Service de Protection de la Communauté Juive (SPCJ) reported a 1000% surge in antisemitic incidents in 2023 compared to the previous year, totaling 1,676 recorded acts. The majority of these incidents targeted individuals, involving threatening words and gestures.

The SPCJ identified "Palestine" as a significant factor, mentioned in almost one-third of antisemitic acts since October 7. Additionally, French Jews reported feeling increasingly unsafe, with a 1,500% increase in antisemitic acts in private spheres and a surge of 1,200% in antisemitic acts within schools or educational settings, often related to Nazism.

Between 7 October and 17 December 2023 over 1,200 French Jews opened Aliyah files to migrate to Israel an increase of 430% compared to last year. Many were driven by a combination of solidarity with Israel as well as rising antisemitism in France.

Between 13 and 14 May 2024, vandals graffitied several sites around The Marais, a historic district home to many Jews, with red handprints, a symbol used by pro-Palestinian activists. Sites vandalized include schools, nurseries, and The Wall of the Righteous, a memorial that honors individuals who saved Jews during the Nazi occupation of France. The incident was described as antisemitic by French President Emmanuel Macron, President of the Conseil Représentatif des Institutions juives de France Yonathan Arfi, and the Union of Jewish Students in France.

The girl was reportedly called a "dirty Jew".

On 27 July 2024, the Paris prosecutor's office launched an investigation into antisemitic crimes in a football match between Israel and Paraguay during the 2024 Summer Olympics.

On 24 August 2024, an 33-year-old Algerian man set fires at the Beth Yacoov synagogue in La Grande-Motte in an attempt to burn it down. The fire caused a gas canister to explode, lightly injuring a police officer. The suspect said that he attacked the synagogue in support of Palestine and wanted to provoke a reaction from Israeli officials.

According to the French Interior Ministry, 1570 antisemitic acts were recorded in 2024, representing 62% of all religiously motivated hate crimes in the country.

In May 2025, France's Holocaust memorial, two synagogues and a restaurant in central Paris were vandalized with green paint, which Mayor Anne Hidalgo called antisemitic.

Germany

In Berlin, on 14 October 2023 at least three houses where Jewish people resided were marked with a Star of David, echoing the marking of Jewish homes and businesses during Nazism.

On 18 October 2023, two Molotov cocktails were thrown at a synagogue in the Mitte neighborhood of central Berlin. One person was arrested. Following the firebombing, German Chancellor Olaf Scholz declared, "Attacks on Jewish institutions and acts of violence on our streets are despicable and cannot be tolerated. Antisemitism has no place in Germany."
