Twenty-five people were arrested Saturday for trespassing at the University of Virginia after police clashed with pro-Hamas protesters who refused to remove tents from campus, and demonstrators at the University of Michigan chanted anti-war messages and waved flags during commencement ceremonies.

In Virginia, student demonstrators began their protest on a lawn outside the school chapel Tuesday. On Saturday, video from WVAW-TV showed police wearing heavy gear and holding shields lined up on the campus in Charlottesville. Protesters chanted “Free Palestine,” and university police said on the social platform X that an unlawful assembly had been declared in the area.

As police moved in, students were pushed to the ground, pulled by their arms and sprayed with a chemical irritant.

The university administration said in a statement that the demonstrators were told the tents and canopies they erected were prohibited under school policy and were asked to remove them. Virginia State Police were asked to help with enforcement, the university said.

Michigan was among the schools bracing for protests during commencement this weekend, including Indiana University, Ohio State University and Northeastern University in Boston. Many more are slated in the coming weeks.

In Ann Arbor, the protest happened 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 graduation 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 flew 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, which was attended by tens of thousands of people, some of them waving Israeli flags.

State police prevented the demonstrators from reaching the stage and university spokesperson Colleen Mastony said public safety personnel escorted the protesters to the rear of the stadium, where they remained through the conclusion of the event.

“Peaceful protests like this have taken place at U-M commencement ceremonies for decades,” she added.

The university has allowed protesters to set up an encampment on campus, but police assisted in breaking up a large gathering at a graduation-related event Friday night, and one person was arrested.

At Indiana, protesters were urging supporters to wear their kaffiyehs and walk out during remarks by President Pamela Whitten on Saturday evening. The Bloomington campus designated a protest zone outside Memorial Stadium, the arena for the ceremony.

At Princeton, in New Jersey, 18 students launched a hunger strike in an effort to push the university to divest from companies tied to Israel.

One of them, senior David Chmielewski said in an email that the strike started Friday morning with participants consuming water only, and it will continue until administrators meet with students about demands including amnesty from criminal and disciplinary charges for protesters.

Other demonstrators are participating in “solidarity fasts” lasting 24 hours, Chmielewski said.

Princeton students set up a protest encampment and some held a sit-in at an administrative building this week, leading to about 15 arrests.

Students at other colleges, including Brown and Yale, launched similar hunger strikes earlier this year before the more recent wave of encampments.

Meanwhile in Medford, Massachusetts, students at Tufts University peacefully took down their encampment without police intervention Friday night.

School officials said they were pleased with the development, which wasn’t the result of any agreement. Protest organizers said in a statement that they were “deeply angered and disappointed” that negotiations with the university had failed.
