The University of Southern California said it will be closing its campus to the public with "significant activity at the center of the [main] campus due to a demonstration," it said in a post on X.

"The gates are closed, so anyone coming to campus should be prepared to show an ID at the gates for class or for business," USC said.

A rally by pro-Palestinian protesters at USC became chaotic after campus police confronted people who tried to set up an encampment at the school's Alumni Park, according to Los Angeles ABC station KABC. The university's commencement ceremony is scheduled to occur in Alumni Park on May 10.

Last week, USC canceled the valedictorian's speech out of safety concerns considering her pro-Palestinian views, sparking backlash. The student, Asna Tabassum, is a first-generation South Asian-American Muslim who majored in biomedical engineering and minored in resistance to genocide, according to a statement published through the Greater Los Angeles Area office of the Council on American-Islamic Relations.

Dozens of students and others have issued a list of demands, including the university's divestment, similar to demands from students on other campuses, according to KABC.

Pro-Palestinian students at Harvard University began an encampment in Harvard Yard on Wednesday, despite the university closing it through Friday.

The encampment comes after Harvard suspended the Harvard Palestine Solidarity Committee -- an on-campus group that has been under a spotlight -- amid debates on campuses over the war. The ACLU of Massachusetts, which represents the group, has called for the university to lift the suspension.

Students and student workers released a statement Wednesday announcing their encampment, calling for the university to divest and accusing it of "relentlessly suppress[ing] voices in its community speaking out against the actions of the Israeli state and for the rights of the Palestinian people," the suspended group said in a statement on Instagram.

The group is also demanding that the university "drop all its charges against students for their organizing and activism, and commit to ending the weaponization of disciplinary policy," the statement said.

Students at the University of Texas at Austin began protesting on campus calling for a divestment, resembling encampments set up at Columbia and Yale University. A similar encampment was set up at New York University before police arrested over 130 students and faculty Monday.

Texas State Troopers were seen marching through campus calling for protesters to disperse.

"Early on Monday, we learned of a plan for a large-scale anti-Israel protest on our UT campus during Passover," Texas Hillel, the center for Jewish Life on campus, said in a statement on Instagram. "The timing of this protest is not lost on us - making use of a Jewish holiday and observance to promote a hateful agenda - and we quickly contacted our university and security partners to begin coordinating a response plan to keep our campus and our students safe."

Austin's Palestine Solidarity Committee wrote on Instagram that "students were welcomed by a draconian police presence, refusing to allow them to use their campus space for political speech."

The Austin Police Department told ABC News its role is only in assisting the UT Police Department, the main agency responding to the campus events. Austin police noted that the Texas Department of Public Safety is also assisting.

California State Polytechnic University's Humboldt campus will be closed through the end of the semester amid ongoing pro-Palestinian protests, the university said Friday.

The campus will be closed through May 10, with remote academic instruction instead, due to the occupation of its Siemens Hall and Nelson Hall East buildings, the university said.

"Since Monday night, protestors have attempted several times to break into multiple locked buildings with the intention of either locking themselves in, vandalizing, or stealing equipment," the university said in a message to the school community. "Vandalism and theft have continued across campus."

The university said protesters -- including students and non-students -- have until 4 p.m. PT Friday to leave the buildings peacefully "with a guarantee of no immediate arrest."

"This does not, however, eliminate University conduct-related sanctions or legal implications," the university added.
