"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.

Linda G. Mills, the president of NYU, posted a statement Friday evening explaining why the school called in the NYPD to break up an encampment on the Greene St. Walkway earlier in the day.

Mills said 14 people who refused orders to leave the area were arrested and the incident was non-violent.

The president said that the police were called in for numerous reasons, including noise complaints from nearby residents and businesses, safety concerns over the crowds of supporters and counter-protesters and escalating threats.

"The encampment had become increasingly untenable for the NYU community and the neighborhood we inhabit," she said.

Mills said three senior administrators spoke with the protesters over the weekend to come to an agreement over shutting down the encampment.

The president said things escalated on Wednesday when a group of people from a May Day march came to the walkway and got into altercations.

The May Day incident and other issues, including threats leveled at NYU administrators, led the school to call the NYPD, according to Mills.

"The university’s senior leadership and I were compelled to conclude that we could not tolerate the risk of violence any longer and that we could not responsibly or in good conscience wait until something drastically worse were to happen in order to act. We needed to bring this to a close," she said.
