Police began dismantling a pro-Palestinian encampment early Thursday at DePaul University in Chicago, hours after the school's president told students to leave the area or face arrest.

Officers and workers in yellow vests cleared out tents and camping equipment at the student encampment, leaving behind yellow squares of dead or dying grass where the tents had stood. Front-loaders were being used to remove the camping equipment.

Just across the street from where the encampment was spread across a grassy expanse of DePaul's campus known as “The Quad”, a few dozen protesters stood along a sidewalk in front of a service station, clapping their hands in unison as an apparent protest leader paced back and forth before them, speaking into a bullhorn.

The move to clear the campus comes less than a week after the school's president said public safety was at risk.

The university on Saturday said it had reached an “impasse” with the school's protesters, leaving the future of their encampment on the Chicago campus unclear. Most of DePaul's commencement ceremonies will be held the June 15-16 weekend.

In a statement then, DePaul President Robert Manuel and Provost Salma Ghanem said they believe that students intended to protest peacefully, but “the responses to the encampment have inadvertently created public safety issues that put our community at risk”.

Efforts to resolve the differences with DePaul Divestment Coalition over the past 17 days were unsuccessful, Manuel said in a statement sent to students, faculty and staff Thursday morning.

“Our Office of Public Safety and Chicago Police are now disassembling the encampment,” he said. “Every person currently in the encampment will be given the opportunity to leave peacefully and without being arrested.”

He said that since the encampment began, “the situation has steadily escalated with physical altercations, credible threats of violence from people not associated with our community.”

Students at many college campuses this spring set up similar encampments, calling for their schools to cut ties with Israel and businesses that support it, to protest lsrael's actions in the war with Hamas. The protests began as schools were winding up their spring semesters and are now holding graduation ceremonies.

Tensions at DePaul flared the previous weekend when counterprotesters showed up to the campus in the city's Lincoln Park neighbourhood and prompted Chicago police to intervene.

The student-led DePaul Divestment Coalition, who are calling on the university to divest from Israel, set up the encampment April 30. The group alleged university officials walked away from talks and tried to force students into signing an agreement, according to a student statement late Saturday.

“I don't want my tuition money to be invested in my family's suffering,” Henna Ayesh, a Palestinian student at DePaul and Coalition member, said in the statement.

DePaul is on the city's North Side. Last week, police removed a similar encampment at the University of Chicago on the city's South Side.

The Associated Press has recorded at least 77 incidents since April 18 where arrests were made at campus protests across the US. About 2,900 people have been arrested on the campuses of 58 colleges and universities. The figures are based on AP reporting and statements from universities and law enforcement agencies. (
