Israel's foreign ministry accused New York City Mayor Zohran Mamdani of antisemitism on his first day in office. The accusation stems from Mamdani's decision to revoke executive orders from his predecessor, which had restricted city agencies from boycotting Israel and adopted the International Holocaust Remembrance Alliance (IHRA) definition of antisemitism. Mamdani defended his actions, stating his criticism of Israel is based on human rights concerns and that he aims to protect Jewish New Yorkers. He also noted that several Jewish groups had raised concerns about the broader IHRA definition.
