College protests updates: Police crackdown leads to hundreds of arrests

Princeton University students began a Gaza solidarity encampment on Thursday, demanding the university divest from Israel and that Israel end its campaign on Gaza.

The students are also calling for an academic boycott of Israel and Israeli universities -- including ending study abroad programs with Tel Aviv University and Hebrew University of Jerusalem, students said in a statement.

"Princeton students stand in solidarity with Columbia University's Gaza Solidarity Encampment, launched on April 17. They strongly condemn the decisions of Columbia University, Yale University, New York University, University of Minnesota Twin Cities, and Cal Poly Humboldt's administrations to employ militarized police against their own students and demand the immediate release of all arrested students, the immediate dropping of all charges, and the immediate revocation of suspensions and evictions," students said in a statement.

"Despite the systematic repression of pro-Palestinian voices, students will continue to stand their ground," students said.

More than 100 people were arrested and four police officers were injured early Thursday when Boston police moved to clear a pro-Palestinian encampment at Emerson College. It is one of several set up by students at Massachusetts colleges including Massachusetts Institute of Technology and Harvard University.

Three of the officers suffered minor injuries and a fourth officer suffered more serious injuries, according to Boston police.

None of the protesters in custody have reported injuries, according to police. The protesters will be arraigned at Boston Municipal Court.

Police arrested 93 people on and around the University of Southern California campus, mostly on misdemeanor trespass Wednesday night.

The university declared the campus closed in the afternoon, open only to students with their USC IDs at pedestrian gates, due to what USC said "significant activity at the center of campus."

On Wednesday night, LAPD Captain Kelly Muniz told ABC News that around 35 protesters had been processed for misdemeanor trespass. Several dozen more were waiting to be processed, Muniz said.

There was an altercation in one portion of the protest area that resulted in one arrest for assault with a deadly weapon, according to Muniz.

There are no known injuries to police or protesters.

The scene will be cleared some time tonight., Muniz said.

At least 34 people had been arrested at the University of Texas at Austin as of 9 p.m. local time, according to the Texas Department of Safety.

"Today, our University held firm, enforcing our rules while protecting the Constitutional right to free speech. Peaceful protests within our rules are acceptable," University President Jay Hartzell said in a statement Wednesday evening.

"Breaking our rules and policies and disrupting others’ ability to learn are not allowed. The group that led this protest stated it was going to violate Institutional Rules. Our rules matter, and they will be enforced. Our University will not be occupied."

"There is a way to exercise freedom of speech and civil discourse, and our Office of the Dean of Students has continued to offer ways to ensure protests can happen within the rules," Hartzell continued.

The dispersal order ended shortly after 9 p.m. and the campus was deemed "all clear," Austin Police said on X.
