Students protesting the war in Gaza abandoned their camp at the University of Southern California early Sunday after being surrounded by police and threatened with arrest, while Northeastern University’s commencement ended peacefully at Boston’s Fenway Park.

Developments in both places were being watched closely following scores of arrests last month — more than 90 people at USC in Los Angeles and about 100 at Northeastern in Boston.

Dozens of Los Angeles Police Department officers arrived about 4 a.m. at USC to assist campus safety officers. The university had warned of arrests on social media and in person. Video showed some protesters packing up and leaving, while officers formed lines to push others away from the camp as it emptied out. The university said there were no reports of any arrests.

USC President Carol Folt said it was time to draw a line because “the occupation was spiraling in a dangerous direction” with areas of campus blocked and people being harassed.

“The operation was peaceful,” Folt wrote in an update. “Campus is opening, students are returning to prepare for finals, and commencement set-up is in full swing.”

USC earlier canceled its main graduation ceremony while allowing other commencement activities to continue.

Across town at the University of California, Los Angeles, officials announced the creation of a new chief safety officer position to oversee campus security operations. The announcement Sunday came after UCLA was criticized for its handling of demonstrations that culminated in a mob attack on a pro-Palestinian student encampment last week.

At the Northeastern commencement Sunday, some students waved small Palestinian and Israeli flags, but were outnumbered by those waving the flags of India and the U.S., among others. Undergraduate student speaker Rebecca Bamidele drew brief cheers when she called for peace in Gaza.

The Associated Press has tallied about 2,500 people arrested at about 50 campuses since April 18, based on its reporting and statements from universities and law enforcement.

Arrests continued apace over the weekend. At the University of Virginia, there were 25 arrests Saturday for trespassing after police clashed with protesters who refused to remove tents. At the Art Institute of Chicago campus, police cleared a pro-Palestinian encampment hours after it was set up Saturday and arrested 68 people, saying they would be charged with criminal trespass.

ARRESTS IN VIRGINIA

In Charlottesville, Virginia, student demonstrators began their protest on a lawn outside the school chapel Tuesday. Video on Saturday showed police in riot gear and holding shields lined up on campus, while protesters chanted “Free Palestine.”

As police moved in, students were pushed to the ground, pulled by their arms and sprayed with a chemical irritant, Laura Goldblatt, an assistant professor who has been helping the demonstrators, told The Washington Post. The university said protesters were told that tents were banned under school policy and were asked to remove them.

Virginia Attorney General Jason Miyares told Fox News on Sunday the police response was justified because students had been warned repeatedly to leave, were violating the school’s conduct code, and that outsiders who were not students provided protesters with supplies like wooden barriers.

“We’ve seen folks that are not students show up in riot gear with bull horns to direct the protesters on how to flank our officers,” Miyares said.

He said some had put bear spray into water bottles and thrown them at officers.

It was the latest clash in weeks of protests and tension at U.S. colleges and universities.

Tent encampments of protesters urging universities to stop doing business with Israel or companies they say support the war in Gaza have spread in a student movement unlike any other this century. Some schools reached agreements with protesters to end the demonstrations and reduce the possibility of disrupting final exams and commencements.

DEMONSTRATIONS AMID COMMENCEMENT

The University of Michigan was among the schools that had braced for protests during commencement this weekend, as were Indiana University, Ohio State University and Northeastern. More ceremonies are planned in the coming weeks.

In Ann Arbor, there was a protest at the beginning of the event at Michigan Stadium. About 75 people, many wearing traditional Arabic kaffiyehs along with their graduation caps, marched up the main aisle toward the stage.

They chanted “Regents, regents, you can’t hide! You are funding genocide!” while holding signs, including one that read: “No universities left in Gaza.”

Overhead, planes pulled banners with competing messages. “Divest from Israel now! Free Palestine!” and “We stand with Israel. Jewish lives matter.”

Officials said no one was arrested, and the protest didn’t seriously interrupt the nearly two-hour event, attended by tens of thousands of people, some of them waving Israeli flags.

OTHER PROTESTS CONTINUE

At Indiana University, protesters urged supporters to wear their kaffiyehs and walk out during remarks by school President Pamela Whitten on Saturday evening. The Bloomington campus designated a protest zone outside Memorial Stadium, where the ceremony was held.

At Princeton University in New Jersey, 18 students began a hunger strike to try to push the university to divest from companies tied to Israel. Students at other colleges, including Brown and Yale, launched similar hunger strikes this year before the more recent wave of demonstrations.

The protests stem 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. 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.
