"Multiple arrests" were made at Virginia Commonwealth University Monday night, following tense conflict between police and pro-Palestinian protesters on the Richmond campus, officials said.

Addressing the arrests, the university said in a statement that final exams start this week and the school "must provide students the opportunity to safely and successfully complete the semester.

"The gathering violated several university policies. VCU respectfully and repeatedly provided opportunities for those individuals involved -- many of whom were not students -- to collect their belongings and leave," the university's statement continued. "Those who did not leave were subject to arrest for trespassing. While supporting an environment that fosters protected speech and expressive activity, VCU must maintain an atmosphere free of disruption to the university’s mission."

A representative from Columbia University said the school began suspending students who have defied the 2 p.m. deadline to leave the encampment.

Ben Chang, the vice president of the office of public affairs, did not say how many people would be suspended but said those students would not be able to attend classes or graduate.

"Students who agree to leave and sign a form committed to abide by university policies will be allowed to complete the semester," he said.

The school's campus is still closed to anyone who doesn't have a student ID.

Chang reiterated that the negotiations with the groups protesting were being done in good faith until discussions broke down.

"We were hopeful and were disappointed when the student protesters could not reach a consensus in the discussion," he said.

Police and protesters clashed on the campus of the University of Texas at Austin on Monday afternoon after authorities issued a dispersal order.

The UT Austin Police Department asked protesters to leave the South Mall area at about 1 p.m. local time.

Protesters could be heard chanting, "There is no riot here, why are you in riot gear?" Soon after, police moved in to clear the area by force.

The university said in a statement, "After protesters ignored repeated directives from both the administration and law enforcement officers to comply with Institutional Rules and remove tents assembled on the University’s South Lawn, then physically engaged with and verbally assaulted Dean of Students staff who attempted to confiscate them, UT and partner law enforcement agencies dismantled an encampment and arrested several protesters."

It continued, "Baseball size rocks were found strategically placed within the encampment. The majority of protesters are believed to be unaffiliated with the university."

More than 50 people were arrested at a pro-Palestinian protest on the campus last week, however, charges were later dropped.

Protesters camped out at Columbia University are defying the school's order to pack up and leave by 2 p.m.

Sueda Polat, a representative from the protesters' negotiating team, told reporters that the university did not engage in good-faith negotiations and failed to meet their demands to divest from Israel.

"It is against the will of the students to disperse," she said. "We do not abide by university pressures. We act on the will of the students."

Police were outside of the campus as the deadline approached but they did not immediately enter after it passed.

"Students are aware of the risk of law enforcement. ... They know how to come together in that risk," Polat said.

NYPD officers entered the campus of the City College of New York late Tuesday night.

"As requested by the university, we are currently on campus to assist the university in dispersing those trespassing," NYPD Deputy Commissioner of Operations, Kaz Daughtry, said in a post on X, sharing video of the police moving in.

In a note to the campus community, university president Vince Boudreau, said protests on campus presented "heightened challenges."

"Most importantly, this is not primarily a CCNY demonstration, and perhaps not primarily a CUNY demonstration. The significant inclusion of un-affiliated external individuals means that we don’t have established connections to them," Boudreau's letter read.

He continued: "Specifically, this demonstration has been more contentious and violent than anything we’ve seen on campus before. Today, we distributed a letter to members of the encampment detailing specific examples of threats to the safety of people within and outside the encampment, so that all of them understand the full scope of the activity. We also want all of them, and those of you reading this note, to understand that in no way does our response to this particular and extraordinary threat overwrite our more fundamental commitments to free speech, academic freedom, or the right to peacefully protest that comply with CCNY and CUNY regulations."

Boudreau said the encamped demonstrators were told to take down their encampment and follow CUNY guidelines for "future activities."

The university president also said classes would be remote on Wednesday due to the situation on campus.
