NEW YORK — Pro-Palestinian protesters that had been blocked by police from accessing an encampment at the Massachusetts Institute of Technology on Monday broke through fencing, linked arms and encircled tents that remained there, as Columbia University canceled its university-wide commencement ceremony following weeks of pro-Palestinian protests.

Sam Ihns, a graduate student at MIT studying mechanical engineering and a member of MIT Jews for a Ceasefire, said the group has been at the encampment for the past two weeks and that they were calling for an end to the killing of thousands of people in Gaza.

“Specifically, our encampment is protesting MIT’s direct research ties to the Israeli Ministry of Defense,” he said.

Protesters also sat in the middle of Massachusetts Avenue, blocking the street temporarily during rush hour in the Boston area. By evening the atmosphere around the MIT protest grew less tense with protesters listening to speeches and joining chants before taking a pizza dinner break.

Police in large part had pulled back from the encampment after offering a more robust presence earlier in the day. An MIT spokesperson said the fencing was breached after the arrival of demonstrators from outside the university and that no arrests had been made by Monday night.

The demonstrations at Columbia have roiled its campus and officials said Monday that while it won’t hold it’s main ceremony, students will be able to celebrate at a series of smaller, school-based ceremonies this week and next.

The decision comes as universities around the country wrangle with how to handle commencements for students whose high school graduations were derailed by COVID-19 in 2020. Another campus shaken by protests, Emory University, announced Monday that it would move its commencement from its Atlanta campus to a suburban arena. Others, including the University of Michigan, Indiana University and Northeastern, have pulled off ceremonies with few disruptions.

Columbia’s decision to cancel its main ceremonies scheduled for May 15 saves its president, Minouche Shafik, from having to deliver a commencement address in the same part of campus where police dismantled a protest encampment last week. The Ivy League school in upper Manhattan said it made the decision after discussions with students.

“Our students emphasized that these smaller-scale, school-based celebrations are most meaningful to them and their families,” officials said.

Most of the ceremonies that had been scheduled for the south lawn of the main campus, where encampments were taken down last week, will take place about 5 miles (8 kilometers) north at Columbia’s sports complex, officials said.

Speakers at some of Columbia’s still-scheduled graduation ceremonies include Pulitzer Prize-winning playwright James Ijames and Dr. Monica Bertagnolli, director of the National Institutes of Health.

Columbia had already canceled in-person classes. More than 200 pro-Palestinian demonstrators who had camped out on Columbia’s green or occupied an academic building were arrested in recent weeks.

Similar encampments sprouted up elsewhere as universities struggled with where to draw the line between allowing free expression while maintaining safe and inclusive campuses.

The University of Southern California earlier canceled its main graduation ceremony. Students abandoned their camp at USC on Sunday after being surrounded by police and threatened with arrest.

Other universities have held graduation ceremonies with beefed-up security. The University of Michigan’s ceremony was interrupted by chanting a few times Saturday. In Boston on Sunday, some students waved small Palestinian or Israeli flags at Northeastern University’s commencement in Fenway Park.

Emory’s ceremonies scheduled for May 13 will be held at the GasSouth Arena and Convocation Center in Duluth, almost 20 miles (30 kilometers) northeast of the university’s Atlanta campus, President Gregory Fenves said in an open letter.

“Please know that this decision was not taken lightly,” Fenves wrote. “It was made in close consultation with the Emory Police Department, security advisors and other agencies — each of which advised against holding commencement events on our campuses.”

The 16,000-student university is one of many that has seen repeated protests stemming from the conflict that started Oct. 7 when Hamas militants attacked southern Israel, killing about 1,200 people, mostly civilians, and taking roughly 250 hostages. Student protesters are calling on their schools to divest from companies that do business with Israel or otherwise contribute to the war effort.

Vowing to destroy Hamas, Israel launched an offensive in Gaza that has killed more than 34,500 Palestinians, about two-thirds of them women and children, according to the Health Ministry in the Hamas-ruled territory. Israeli strikes have devastated the enclave and displaced most of its inhabitants.

Hamas on Monday announced its acceptance of an Egyptian-Qatari cease-fire proposal, but Israel said the deal did not meet its “core demands” and that it was pushing ahead with an assault on the southern Gaza town of Rafah.

“Cease-fires are temporary,” said Selina Al-Shihabi, a Georgetown University sophomore who was taking part in a protest at George Washington. “There can be a cease-fire, but the U.S. government will continue to arm the Israeli military. We plan to be here until the university divests or until they drag us out of here.”

At the University of California, San Diego, police cleared an encampment and arrested more than 64 people, including 40 students.

The University of California, Los Angeles, moved all classes online for the entire week due to ongoing disruptions following the dismantling of an encampment last week. The university police force reported 44 arrests but there were no specific details, UCLA spokesperson Eddie North-Hager said in an email to The Associated Press.

Schools are trying various tactics from appeasement to threats of disciplinary action to get protestors to take down encampments or move to campus areas where demonstrations would be less intrusive.

The School of the Art Institute of Chicago said in a Facebook post Sunday that it offered protesters “amnesty from academic sanction and trespassing charges” if they moved.

“Many protesters left the premises of their own accord after being notified by the police that they were trespassing and subject to arrest,” the school said. “Those that remained were arrested after multiple warnings to leave, including some of whom we recognized as SAIC students.”

A group of faculty and staff members at University of North Carolina at Chapel Hill asked the administration for amnesty for any students who were arrested and suspended during recent protests. UNC Faculty and Staff for Justice in Palestine said in a media advisory that it would deliver a letter on behalf of more than 500 faculty who support the student activists.

Other universities took a different approach.

Harvard University’s interim president, Alan Garber, warned students that those participating in a pro-Palestinian encampment in Harvard Yard could face “involuntary leave.” That means they would not be allowed on campus, could lose their student housing and may not be able to take exams, Garber said.
