Following the April 8, 2026 ceasefire, which halted the 40-day-long U.S. and Israeli military operation against the Islamic Republic of Iran, official Iranian regime diplomatic accounts on X have posted a stream of antisemitic content to audiences of millions. In a campaign the New York Times referred to as “information warfare,” spanning at least four embassies across three continents, Iranian missions in Indonesia, South Africa, Tajikistan, and Zimbabwe have published…

Since March 9, 2026, a previously unknown group calling itself Harakat Ashab al-Yamin al-Islamiya (HAYI) has claimed responsibility for a rapidly increasing series of attacks on Jewish and Israel-linked institutions across Europe, including in Belgium, France, Germany, the Netherlands, North Macedonia, and the United Kingdom. In the past few weeks, synagogues were bombed or firebombed in Liege, Rotterdam, Skopje, Kenton, Finchley and Hendon; explosive devices were detonated near a Jewish…

At a moment when the Islamic Republic of Iran is at the center of a regional war, it is important to remember that the Iranian regime's decades-long promotion of antisemitism is not merely ideological, it is operational. Since 1979, the Islamic Republic of Iran has been the world's leading state sponsor of terrorism, antisemitism and Holocaust denial.  The regime has embedded anti-Jewish hatred into its core identity and translated it into policy, propaganda and violence. Persecution…

Ali Larijani, the former secretary of the Islamic Republic of Iran's Supreme National Security Council killed on March 17, had emerged after the killing of Supreme Leader Ayatollah Ali Khamenei on February 28, 2026, as one of the most powerful surviving Iranian regime figures, with analysts assessing that he had "effectively been running” Iran. Larijani was revered by his admirers because he combined military service in the Iran-Iraq war with theological and intellectual…

A day after Iranian Supreme Leader Ayatollah Ali Khamenei was killed during an attack by Israel and the United States on February 28, 2026, Alireza Arafi was appointed as the Islamic Republic of Iran’s interim leader as a member of the Leadership Council, which is tasked with fulfilling the supreme leader’s role until the Assembly of Experts elects a new leader. A review of Arafi’s public statements, especially open letters reproduced on the Guardian Council…

Kneecap, the Irish hip-hop trio, has made headlines for their onstage anti-Israel comments, support of designated terrorist organizations, and pro-BDS activities. As of August 26, 2025, Kneecap cancelled its sold-out October tour of the US amid a legal battle and pushback concerning their uninhibited support for extremist organizations in their activism. In February 2025, Kneecap posted a picture of a band member reading a book of statements by the terrorist organization Hezbollah’s…

The Islamic Republic of Iran is the world’s leading state sponsor of terrorism, antisemitism, and Holocaust denial and distortion. Anti-Jewish and anti-Israel hate and incitement have been a core pillar and a defining feature of the Iranian regime, promoted through state media, educational system, religious sermons and international propaganda, including through Holocaust cartoon contests and annual Quds Day rallies. Since its founding in 1979, through the Islamic Revolutionary Guard…

On January 20, 2025, President Donald Trump designated the Houthis (also called “Ansar Allah”), the Islamic Republic of Iran’s terror proxy in Yemen, as a Foreign Terrorist Organization (FTO). This adds to their previous designation under the Biden administration as Specially Designated Global Terrorists (SDGT). Together, the FTO and SDGT designations allow the US Government to target the Houthis more effectively. The Houthis have been launching missile and drone attacks…

On November 27, 2024, Syrian rebel groups launched a major offensive against the regime of Bashar Al-Assad. Within days, forces led by Hayat Tahrir Al-Sham (HTS), and supported by the Turkey-backed Syrian National Army and a range of anti-Assad militias, had taken Aleppo and Hama. On December 8, 2024, the rebel forces took Damascus, forcing Assad to flee the country. The HTS leadership quickly assumed control of government institutions, appointed an interim prime minister, and declared itself…

Francesca Albanese, appointed in May 2022 as the United Nations Special Rapporteur on the occupied Palestinian territories, has long coopted antisemitic tropes and legitimized support of terrorism in her critiques of Israel, using her platform to spread intense anti-Israel rhetoric. She is the first Special Rapporteur to be condemned by both Germany and France for antisemitism and was condemned by then U.S. Special Envoy to Combat Antisemitism Deborah Lipstadt, then U.S. Ambassador to the UN…

By Carole Nuriel, ADL Senior Regional Director, Israel and MENA  On the evening of October 6th, 2023, my extended family gathered at my parents' home to mark the 50th anniversary of the Yom Kippur War. As we listened to them recall the surprise and shock of that day, and the personal and national responses to the war, I was reminded of how that conflict, whose leadup became known as "the mother of all intelligence failures", led Israel on a…

Marina Rosenberg The attack on Israel by Hamas on October 7, 2023, had profound and far-reaching effects on Israelis, Jewish communities around the world and many others.  Across Latin American, several Jewish communities faced a sharp rise in antisemitic incidents, diverse government responses, and escalating security concerns. The aftermath of this attack has not only exposed the vulnerability of Jewish populations in the region but has also highlighted the complex geopolitical dynamics…

Riots across the United Kingdom involving far-right elements broke out after the murder of three young girls at a dance class in the Southport knife attack was falsely attributed to a recently arrived Muslim migrant. It is predictable but still problematic to see Israel scapegoated as the cause of the riots raging across the United Kingdom involving far-right elements. This is happening across social media. The claims have no basis and contribute to the increasing anxiety among the Jews in the…

Ismail Haniyeh, who was killed on July 31, 2024 in Tehran, led the so-called politburo of Hamas, a US-designated Islamist terror organization dedicated to the destruction of the State of Israel and the establishment of an Islamic state between the Jordan River and the Mediterranean Sea. Hamas’ founding covenant issued in 1988, which echoes the notorious Protocols of the Elders of Zion charging Jews with an international conspiracy to gain control of the world, is…

The death of Saleh Al-Arouri, a leading Hamas financier and military leader on January 2, 2024, resulted in threats of retribution against Israel by Hamas, Hezbollah and other regional proxies of the Islamic Republic of Iran. Similar to the killing of Qassim Soleimani, the head of Quds Force, in 2020 in Baghdad, and the killing of Seyed Razi Mousavi, a senior adviser of the Islamic Revolutionary Guards Corps – Quds Force (IRGC-QF), in 2022 in Syria, Al-Arouri's death led to vitriol and…
