Police arrested dozens of people at pro-Palestinian demonstrations at Yale University in Connecticut and New York University in Manhattan on Monday, as the onslaught in Gaza continued to reverberate through US university campuses, Reuters reports.

The police crackdowns came after Columbia University canceled in-person classes on Monday in response to protesters setting up tent encampments at its New York City campus last week.

Demonstrators blocked traffic around Yale’s campus in New Haven, Connecticut, demanding the school divest from military weapons manufacturers. Police arrested more than 45 protesters, according to the student-run Yale Daily News.

In New York, officers moved on the NYU crowd shortly after nightfall as hundreds of demonstrators for hours had defied university warnings that they faced consequences if they failed to vacate a plaza where they had gathered. Video on social media showed police taking down tents in the protesters’ encampment.

As demonstrators tussled with officers and chanted, “We will not stop, we will not rest. Disclose. Divest.”

A New York police spokesperson said arrests were made after the university asked police to enforce trespassing violations but the total number of arrests and citations would remain unknown until much later.

No immediate injuries were reported.
