PHILADELPHIA (AP) — Protesters packed up their belongings and left a pro-Palestinian encampment at Drexel University on Thursday after the school announced a decision to have police clear the encampment.

University President John Fry said in a statement that he decided to have campus police and public safety officers join Philadelphia police in clearing the encampment as peacefully as possible. News outlets reported that police gave protesters a warning to clear the encampment and protesters left. Protesters didn’t immediately comment.

Fry said the university is committed to protecting the community members’ right to assemble peacefully and express their views, but he has the responsibility and authority to regulate campus gatherings to ensure safety and fulfill the mission to educate students.

“An unauthorized encampment that involves large numbers of people unaffiliated with Drexel trespassing on our campus is illegal,” Fry said. “The language and chants coming from this demonstration, underscored by protestors’ repugnant ‘demands,’ must now come to an end.”

Protesters gathered their belongings as dozens of officers on bicycles arrived around 5:20 a.m., but in less than a half hour only a few items remained on the Korman Family Quad where the 35-tent encampment had been, the Philadelphia Inquirer reported.

“The campers picked up their belongings for the most part and left by their own free will,” Philadelphia Police Sgt. Eric Gripp said.

The encampment had persisted despite Fry’s threat earlier this week to have the encampment cleared. Fry said Tuesday that classes would be held virtually for a third day on Wednesday after administrators tried to open a line of communication to the protesters but were rebuffed. News outlets reported that the university announced Wednesday night that the campus would return to normal operations Thursday.

In his statement early Thursday, Fry said previous requests for protesters to disperse had been ignored, but he was asking Drexel affiliates to leave the encampment so police could “escort any remaining trespassers off our campus.”

A wave of pro-Palestinian tent encampments on campuses has led to over 3,000 arrests nationwide.

Harvard University planned to hold its commencement Thursday following a weekslong pro-Palestinian encampment. Tensions on campus ticked up a notch Wednesday when officials announced that 13 students who participated in the encampment won’t receive degrees alongside their classmates.

Also Thursday, the leaders of Northwestern University and Rutgers University are expected to testify at a House Committee on Education and the Workforce hearing about concessions they gave to pro-Palestinian protesters to end demonstrations on their campus. The chancellor of the University of California, Los Angeles, also was scheduled to appear at the latest in a series of hearings looking into how colleges have responded to the protests and allegations of antisemitism.
