Harvard University has closed Harvard Yard at the heart of its campus and is restricting access to the outside area until Friday, according to a report, a move that comes as anti-Israel protesters take over open areas of other Ivy League campuses.

Signs posted on the gates of Harvard Yard on Sunday said that the area was closed to non-Harvard ID holders and that "structures, including tents and tables" are not permitted without prior permission, the Harvard Crimson first reported.

Blocking pedestrian pathways and access to building entrances was also prohibited, according to the Crimson. The university said that students who violate these policies are subject to disciplinary action.

Fox News Digital reached out to Harvard University but did not immediately receive a response.

The announcement comes after more than 200 anti-Israel protesters gathered in Harvard Yard on Friday and demanded that the university divest from Israeli companies and investments in the West Bank. 

It also follows anti-Israel protesters setting up encampments with tents on the campuses of Yale University and Columbia University.

On Monday morning, police arrested 47 protesters at Yale University in Connecticut and charged them with misdemeanor trespassing after a week of campus protests.

Outside New York University (NYU), camps with tents were seen set up Monday morning.

An NYU spokesperson told Fox News in a statement that about 50 protesters began demonstrating on the plaza in front of the university’s business school without notifying the university. Picketers were also gathered on the sidewalk in front of the plaza.
