Student protests over the Israel-Hamas war have popped up on an increasing number of college campuses following the arrest of more than 100 demonstrators at Columbia University.

The students are calling for universities to separate themselves from any companies that are advancing Israel's military efforts in Gaza – and in some cases from Israel itself.

Protests on many campuses have been orchestrated by coalitions of student groups. The groups largely act independently, though students say they're inspired by peers at other universities.

Here's a look at the protests on campuses in recent days:

Columbia

Pro-Palestinian student protesters set up a tent encampment at the Ivy League university in New York. Police first tried to clear the encampment, when they arrested more than 100 protesters. But the move backfired, acting as inspiration for other students across the country and motivating protesters at Columbia to regroup.

University officials said that they were extending a deadline for protesters to clear out. They said the demonstrators had committed to removing a significant number of tents and agreed that only students would remain at the encampment. They also said they would make the encampment more welcoming by banning any discriminatory language or harassing messages.

Ben Chang, a spokesperson for Columbia, said discussions with student protesters were continuing. He said university leaders hope the talks lead demonstrators to remove the encampment, but otherwise Columbia will have to consider other options.

“We have our demands; they have theirs,” he said.

US Representative Ilhan Omar, whose daughter was among those arrested at Columbia last week, visited the campus, meeting with protesters. “I’m in awe of their bravery and courage,” she said.

University of Southern California

The University of Southern California has canceled its main stage graduation ceremony as its campus is roiled by protests. The university already canceled a commencement speech by the school’s pro-Palestinian valedictorian, citing safety concerns.

The Los Angeles Police Department said more than 90 people were arrested on Wednesday night for alleged trespassing during a protest at the university. One person was arrested for alleged assault with a deadly weapon.

LAPD Captain Kelly Muniz said that there was an altercation, but she did not have specific details. There were no reports of injuries. The university said it had closed campus and police would arrest people who did not leave.

Earlier in the day police removed several tents, then got into a back-and-forth tent tugging match with protesters before falling back. At one point, USC police detained a man and put him in a vehicle. A crowd surrounded the car and chanted “Let him go!” and the officers eventually did so.

University of Texas at Austin 

The University of Texas campus was much calmer a day after a demonstration saw police and state troopers in riot gear and on horseback make dozens of arrests and force hundreds of students off the school’s main lawn.

University officials pulled back the campus barricades and allowed another demonstration involving students and some faculty on the main square underneath the school’s iconic clock tower. The group was also protesting the Wednesday arrests.

While the group was vocal with chants and angry shouts against Israel and campus leadership, the demonstration was far less volatile. No violence erupted as a small group of campus police watched from the steps of the tower building. The gathering lasted about two hours.

University President Jay Hartzell said Thursday that 26 of the 55 people arrested on Wednesday had no affiliation with the university.

“I am grateful that everyone is safe after yesterday, we continue to hold in-person classes, and that today’s events followed our long-standing campus standards for allowed demonstrations,” he said.

George Washington University

About 50 students at George Washington University set up a tent encampment on the school’s University Yard.

The protest at the Washington, DC-based school grew steadily through the morning, with demonstrators waving Palestinian flags, beating drums and chanting slogans.

Later in the day, a group of Georgetown University students and professors staged their own protest walkout and marched to the George Washington campus to join the protesters there.

Despite a robust police presence on the edges of the encampment, there were no serious incidents. According to social media reports, one pro-Israeli protestor waving an Israeli flag attempted to march through the center of the protest but was led away by police.

The protestors are demanding that the university divest from all relations with Israel and lift a suspension against a prominent pro-Palestinian student group.

The university was moving law school finals, which were set to be held in a building next to the encampment, to another building because of the noise.

The university said peaceful demonstrations were permitted, however people not associated with the university were not allowed to protest on campus and overnight encampments were not allowed on university property. It said the protesters must remove tents and disperse by 7pm.

Harvard 

Trying to stay ahead of protests, Harvard, in Cambridge, Massachusetts, locked most gates into its famous Harvard Yard ahead of classes and limited access to those with school identification.

The school also posted signs warning against setting up tents or tables on campus without permission.

Those efforts didn't stop protesters from setting up a camp with 14 tents Wednesday, which came after a rally against the university's suspension of the Harvard Undergraduate Palestine Solidarity Committee.

California State Polytechnic University, Humboldt 

Protesters at the university used furniture, tents, chains and zip ties to block entrances to an academic and administrative building.

Protesters chanted, "We are not afraid of you!" before officers in riot gear pushed into them at the building's entrance, video shows.

University officials closed the campus through this weekend, saying instruction would continue to be remote.

They said in a statement that students had occupied a second building and three students had been arrested. On Wednesday, officials said some unidentified people who are not students were also inside one of the occupied buildings.

On Thursday, the university said protesters continued to occupy the two buildings on campus and it was making contingency plans, including possibly keeping campus closed beyond Sunday. Later in the day, faculty members met with protesters, trying to negotiate a solution.

Emerson College

Boston Police said that 108 people were arrested at an encampment at Emerson College. Police said four officers suffered injuries that weren't considered life-threatening. 

On Tuesday, about 80 students and other supporters at Emerson College occupied a busy courtyard on the downtown Boston campus.

College officials warned the students on Wednesday that some of the protesters were in violation of city ordinances, including by blocking a right-of-way and fire hydrants, and violating noise laws.

The school said the alley where some protesters have set up tents is owned by the city, and Boston police have warned of imminent law enforcement action.

The college said in a statement that campus police were offering escort services for students after officials received credible reports of some protesters engaging in "targeted harassment and intimidation of Jewish supporters of Israel".

New York University

At New York University, an encampment set up by students swelled to hundreds of protesters.

Police on Wednesday said that 133 protesters had been taken into custody. They said all were released with summonses to appear in court on disorderly conduct charges.

Emory University 

Atlanta police and Georgia state troopers dismantled a camp on Emory University’s quadrangle on Thursday morning, with at least 17 people detained.

University police had ordered several dozen demonstrators who set up tents on the campus early on Thursday morning to leave, according to Emory spokeswoman Laura Diamond. She said the group “trespassed” onto the private school.

“These individuals are not members of our community,” Diamond said. “They are activists attempting to disrupt our university as our students finish classes and prepare for finals.”

A long line of officers surrounded the encampment of about three dozen tents as protesters chanted slogans supporting Palestinians and opposing a public safety training center being built in Atlanta.

The two movements are closely entwined in Atlanta, where there has been years of “Stop Cop City” activism that has included a fringe of anarchist attacks on property and the killing by state troopers of a protester who was occupying the site.

Cheryl Elliott, Emory's vice president for public safety, said that 28 people were arrested, including 20 members of the university community. Some had already been released.

Northwestern University

Northwestern University changed its student code of conduct on Thursday morning to bar tents on its suburban Chicago campus as student activists set up an encampment.

Groups including Jewish Voice for Peace and Educators for Justice in Palestine said the encampment on the Evanston campus was “a safe space for those who want to show their support of the Palestinian people”. The students want the university to divest from Israel, among other things.

Dozens participated as University President Michael Schill issued an email saying the university had enacted an “interim addendum” to its student code to bar tents, among other things, and warned of disciplinary actions including suspension, expulsion and criminal charges.

“The goal of this addendum is to balance the right to peacefully demonstrate with our goal to protect our community, to avoid disruptions to instruction and to ensure university operations can continue unabated,” Schilling said.

No arrests had been made by Thursday midafternoon.

Yale

Protests continued at Yale, though the number of students involved had visibly shrunk since Monday, when 48 people, including 44 students, were arrested and charged with trespassing after camping out for several days on Beinecke Plaza.

The vast majority of those arrested were charged with trespassing. Classes for the semester at the New Haven, Connecticut-based school are scheduled to end on Friday, with final exams May 2 through 8.

Fashion Institute of Technology

A few dozen protesters set up tents and occupied a building \ at the Fashion Institute of Technology, part of the public State University of New York system.

Protesters sat on the floor or milled around, many wearing face masks and keffiyas. Other protesters outside the building held signs and Palestinian flags. They refused to speak to a reporter.

The City College of New York

Students at The City College of New York in Harlem set up an encampment. On Thursday evening, a mix of New York police officers and campus security guards confronted protesters.

But they were quickly outnumbered by protesters, who locked arms and cut off their path. The officers retreated, drawing cheers from the encampment.

Indiana University Bloomington

Police with shields and batons shoved into a line of protesters linked arm in arm at Indiana University Bloomington on Thursday afternoon, arresting 33 people. Police made the arrests after an encampment was set up on campus.

Videos posted to social media appear to show the protest continuing after law enforcement stopped making arrests.

Michigan State University

Tents began to appear on Michigan State University’s East Lansing campus early on Thursday, with nearly 30 tents set up by late afternoon, and about 100 students gathered near the campus center, engaging in chants.

Eli Folts, an organizer who is junior at the university, said that many of the students felt comfortable showing their faces “partially because of the police response”.

He said “police liaisons” had been assigned to interact with the police officers, who have come by the encampment about every hour.

Michigan State’s new president, Kevin Guskiewicz, also stopped by the encampment earlier in the day to speak with protesters.

University of Connecticut

Police arrested one protester and tore down tents at the University of Connecticut on Thursday, after students set up an encampment.
