HAYI’s 2026 Campaign: Coordinated Attacks on Jewish Communities Across Europe Linked to Iranian Proxies
Overview
In early 2026, following US and Israeli strikes on Iran, a sudden wave of attacks targeted Jewish sites across Europe, including London, Belgium, and the Netherlands. These attacks, claimed by the newly emerged group HAYI, are believed to be part of Iran's asymmetric retaliation campaign using local criminal networks to carry out low-tech arson and bombings. The assaults caused widespread fear in Jewish communities and prompted increased security measures and government condemnations. While the EU designated Iran's IRGC as a terrorist organization, the UK faced criticism for not doing so. This campaign highlights Iran's use of proxy groups to inflict psychological terror while maintaining plausible deniability, posing a complex security challenge for Europe.
