The alleged threats alarmed students and focused more national attention on the rise in antisemitism and Islamophobia since the start of the Israel-Hamas war.

A 21-year-old Cornell University junior was charged Tuesday for making online threats to Jewish students at the Ivy League school, authorities said.

Patrick Dai, a junior at Cornell, faces a charge of posting threats to kill or injure another using interstate communications, federal prosecutors in the Northern District of New York said.

In a post in an online discussion board, prosecutors said, the student allegedly threatened to "shoot up" a campus building. In another post, he said he he would "stab" or "slit the throat" of Jewish men, and rape or throw off a cliff Jewish women he encounters on campus, according to the prosecutors.

He also said he would behead Jewish babies and threatened to "bring an assault rifle to campus and shoot all you" Jewish people, prosecutors said, attributing the words to Dai.
