New York University (NYU) was sued on Tuesday by three Jewish students who accused the school of creating a hostile environment in which Jewish students are subjected to pervasive anti-Semitic hatred, discrimination, harassment and intimidation, Reuters reports.

Bella Ingber, Sabrina Maslavi and Saul Tawil said NYU has refused to enforce anti-discrimination policies that it “readily applies” to protect other targets of bigotry, including by allowing chants such as “gas the Jews” and “Hitler was right.”

In a complaint filed in Manhattan federal court, the plaintiffs, all juniors, said anti-Semitism had been a “growing institutional problem” at NYU even before the escalation between Israel and Hamas began last month, and has since gotten worse.

According to the complaint, Mills this month dismissed a petition from 4,000 NYU members expressing concern about anti-Semitism, saying the problem had been blown “out of proportion” and chiding Jewish students as “alarmist.”

“NYU looks forward to setting the record straight, to challenging this lawsuit’s one-sided narrative, to making clear the many efforts NYU has made to combat anti-Semitism and provide a safe environment for Jewish students and non-Jewish students, and to prevailing in court,” John Beckman, an NYU spokesman said in a statement.
