Violent Antisemitic Attacks Erupt in West After Israel-Iran War

Violent Attacks Strike Four Western Nations in March 2026

Jewish communities across the West faced a surge of violent attacks in March 2026, escalating concerns over global security. In Liège, Belgium, an Improvised Explosive Device (IED) was detonated outside a historic synagogue, marking the city's first such attack since the Holocaust. Within the same three-week period, four Jewish charity ambulances were firebombed in London, a man rammed his vehicle into Temple Israel in Michigan while 140 children were inside, and three synagogues in Toronto were hit by gunfire. An arson attack also damaged a synagogue in Rotterdam.

A previously unknown group, the Islamic Movement of the Companions of the Righteous, claimed responsibility for the attacks in Liège, London, and Rotterdam. According to the European Jewish Congress, several European governments suspect the group has links to Iran, directly connecting the violence to state actors.

Global Incidents Spike 34% After Israel-Iran War Begins

The surge in violence is tied to the war launched by the U.S. and Israel against Iran in February 2026. Data from the Antisemitism Research Center showed a 34% increase in global incidents against Jewish communities in the week of March 5, with nearly half linked to the conflict. This follows a trend of rising hostility since the October 7, 2023 attack on Israel, which analysts say has been amplified by social media and exploited by extremist ideologies. Research from the Combat Antisemitism Movement (CAM) concluded that the far-left and Islamists were responsible for over 80% of global antisemitic incidents in 2025.

Experts note the convergence of radical Islamic beliefs with anti-Jewish sentiment on both the far-left and far-right. While criticism of Israeli government policy is distinct from antisemitism, rhetoric calling to “globalize the intifada” at protests is interpreted by many Jews as a direct call for violence, creating a climate where attacks become more likely.

Communities Bolster Security as Fear Mounts

The attacks have forced Jewish communities to implement extensive security measures, with concrete barriers and security personnel becoming commonplace outside synagogues and schools. This tangible threat has created a pervasive sense of fear, causing some to hide visible signs of their faith. In Belgium, one monitoring organization recorded an 80% increase in antisemitic acts between 2024 and 2025. The escalating hostility has led to an increase in Jews considering emigration from Europe and North America.

It feels like the 1930s.

This sentiment is reflected in data from the American Jewish Committee, which found that 17% of American Jews have considered leaving the country in the past five years due to antisemitism. Despite increased coordination with law enforcement, the series of attacks demonstrates that even robust security can be overcome, forcing communities into a state of heightened and continuous alert.
