Early Monday morning, police in riot gear began swarming the Yale University campus in Connecticut where hundreds of students were staging an anti Israel protest.

Online footage showed cops blocking the entrance to the plaza on the New Haven campus, where 200 protesters had gathered.

The Yale Daily News reported that police have begun warning protestors to leave the area or risk arrest.

It was not immediately clear whether anyone had yet been arrested.

A Jewish student reporter who was covering the protests in Yale, which began on Friday, was stabbed with a Palestinian flag by a student Saturday night.

Sahar Tartak was covering a protest for the Yale Free Press when she suddenly found herself surrounded by demonstrators.

Tartak, a reporter for The Post, said: “I’ve had hundreds of people taunt me by waving their middle fingers at me. Then this person waves the Palestinian flag and pokes it into my eye.”

When I tried to shout and run after him, protesters formed a line in front of me and stopped my progress.

Yale President Peter Salovey warned students in an email sent late Sunday that the school would “pursue disciplinary action according to its policy” amid the ongoing protests.

Many of the students who participated in the protests and counterprotests did so peacefully. “I am aware that there have been reports of some egregious acts, including intimidation, harassment, pushing people in the crowd, removal of plaza flags and other harmful actions,” he wrote.

Yale does not tolerate any actions or remarks that harass, threaten, or intimidate the Jewish, Muslim and other communities at Yale.

The Yale Police Department investigates each report and will take appropriate action, including referring students for discipline, when necessary.

More than 100 protesters had been cuffed, and taken away by the NYPD when they were called to clear a similar demonstration at Columbia University.
