The University of Massachusetts Amherst is not doing enough to combat antisemitism on campus, according to a federal complaint filed this week by the Anti-Defamation League and Louis D. Brandeis Center for Human Rights in Boston.

During that violent attack in November, UMass Amherst senior Dylan Jacobs was reportedly called a “Zionist s***bag” and then punched and kicked repeatedly by another student. A small Israeli flag was ripped from his hand, stabbed and thrown in a trash can.

The filing comes six months after a student was arrested and banned from campus for allegedly assaulting a Jewish student and vandalizing an Israeli flag.

The University of Massachusetts-Amherst has failed to address a “hostile antisemitic environment” against Jewish students on its campus, according to a federal complaint filed this week by the Anti-Defamation League.
