Dueling groups of protesters clashed Wednesday at the University of California, Los Angeles, grappling in fistfights and shoving, kicking and using sticks to beat one another. Hours earlier, police burst into a building at Columbia University that pro-Palestinian protesters took over and broke up a demonstration that had paralyzed the school while inspiring others.After a couple of hours of scuffles between pro-Palestinian and pro-Israeli demonstrators at UCLA, police wearing helmets and face shields formed lines and slowly separated the groups. That quelled the violence, and the scene was calm as day broke.Tent encampments of protesters calling on universities to stop doing business with Israel or companies that support the war in Gaza have spread across the country in a student movement unlike any other in the 21st century, reaching from New York to Texas and California. The ensuing crackdown by police on some college campuses has stirred echoes of the much larger student protest movement during the Vietnam War era.There have been confrontations with law enforcement and more than 1,000 arrests. In rarer instances, university officials and protest leaders struck agreements to restrict the disruption to campus life and upcoming commencement ceremonies.The clashes at UCLA took place around a tent encampment built by pro-Palestinian protesters, who erected a line of parade barricades, plywood and wooden pallets at the edge of the camp 맥스카지노� while counter-protesters tried to pull them down. Video showed fireworks exploding over and in the encampment.People threw chairs and other objects and at one point a group piled on a person who lay on the ground, kicking and beating them with sticks until others pulled them out of the scrum.It was not clear how many people might be injured.Video below: NYPD arrest pro-Palestinian protesters at ColumbiaLos Angeles Mayor Karen Bass called the violence 맥스카지노�absolutely abhorrent and inexcusable" in a post on social media platform X and said officers from the Los Angeles Police Department were on the scene. Officers from the California Highway Patrol also appeared to be there. The university said it had requested help.Security was tightened Tuesday at the campus after officials said there were 맥스카지노�physical altercations맥스카지노� between factions of protesters. UCLA announced classes were canceled Wednesday, saying on X: 맥스카지노�Due to the distress caused by the violence that took place on Royce Quad late last night and early this morning, all classes are cancelled today. Please avoid the Royce Quad area.맥스카지노�Late that same day, New York City officers entered Columbia's campus after the university requested help, according to a statement released by a spokesperson. A tent encampment on the school's grounds was cleared, along with Hamilton Hall where a stream of officers used a ladder to climb through a second-floor window. Protesters seized the hall at the Ivy League school about 20 hours earlier.맥스카지노�After the University learned overnight that Hamilton Hall had been occupied, vandalized, and blockaded, we were left with no choice,맥스카지노� the school said. 맥스카지노�The decision to reach out to the NYPD was in response to the actions of the protesters, not the cause they are championing. We have made it clear that the life of campus cannot be endlessly interrupted by protesters who violate the rules and the law.맥스카지노�A few dozen people were arrested at the building after protesters shrugged off an earlier ultimatum to abandon the encampment Monday or be suspended and unfolded as other universities stepped up efforts to end demonstrations that were inspired by Columbia. Fabien Lugo, a first-year accounting student who said he was not involved in the protests, said he opposed the university맥스카지노�s decision to call in police.맥스카지노�This is too intense,맥스카지노� he said. 맥스카지노�It feels like more of an escalation than a de-escalation.맥스카지노�Just blocks away from Columbia, at The City College of New York, demonstrators were in a standoff with police outside the public college맥스카지노�s main gate. Video posted on social media by news reporters on the scene late Tuesday showed officers putting some people to the ground and shoving others as they cleared people from the street and sidewalks.After police arrived, officers lowered a Palestinian flag atop the City College flagpole, balled it up and tossed it to the ground before raising an American flag.Brown University, another member of the Ivy League, reached an agreement Tuesday with protesters on its Rhode Island campus. Demonstrators said they would close their encampment in exchange for administrators taking a vote to consider divestment from Israel in October. The compromise appeared to mark the first time a U.S. college has agreed to vote on divestment in the wake of the protests.Meanwhile, at Northern Arizona University in Flagstaff, police in riot gear closed in on an encampment late Tuesday and arrested about 20 people for trespassing, at least one of whom was thrown to the ground. University officials had warned earlier in the day that students would face criminal charges if they did not disperse.First-year student Brayden Lang watched from the sidelines. 맥스카지노�I still know very little about this conflict,맥스카지노� he said. 맥스카지노�But the deaths of thousands is something I cannot stand for.맥스카지노�Police also cleared an encampment at Tulane University early Wednesday.The nationwide campus protests began at Columbia in response to Israel맥스카지노�s offensive in Gaza after Hamas launched a deadly attack on southern Israel on Oct. 7. Militants killed about 1,200 people, most of them civilians, and took roughly 250 hostages. Vowing to stamp out Hamas, Israel has killed more than 34,000 Palestinians in the Gaza Strip, according to the Health Ministry there.As cease-fire negotiations appeared to gain steam, it wasn맥스카지노�t clear whether those talks would lead to an easing of protests.Israel and its supporters have branded the university protests as antisemitic, while Israel맥스카지노�s critics say it uses those allegations to silence opposition. Although some protesters have been caught on camera making antisemitic remarks or violent threats, organizers of the protests, some of whom are Jewish, say it is a peaceful movement aimed at defending Palestinian rights and protesting the war.Columbia's police action happened on the 56th anniversary of a similar move to quash an occupation of Hamilton Hall by students protesting racism and the Vietnam War.The police department earlier Tuesday said officers wouldn't enter the grounds without the college administration맥스카지노�s request or an imminent emergency. Now, law enforcement will be there through May 17, the end of the university's commencement events.In a letter to senior police officials, Columbia President Minouche Shafik said the administration made the request that officers remove protesters from the occupied building and a nearby tent encampment 맥스카지노�with the utmost regret.맥스카지노�New York City Mayor Eric Adams said on MSNBC맥스카지노�s 맥스카지노�Morning Joe맥스카지노� that police had to move into Hamilton Hall 맥스카지노�for the safety of those children.맥스카지노�He again blamed outside agitators for the building takeover 맥스카지노� an idea Shafik has also raised, though neither provided specific evidence to back up the contention, which was disputed by protest organizers and participants.The police department맥스카지노�s deputy commissioner for public information, Tarik Sheppard, said 40 to 50 people were arrested at Hamilton Hall and that there were no injuries.Adams later said that about 300 people were arrested in police crackdowns at Columbia University and City College.Protesters first set up a tent encampment at Columbia almost two weeks ago. The school sent in police to clear the tents the following day, arresting more than 100 people, only for the students to return.Negotiations between the protesters and the college came to a standstill in recent days, and the school set a deadline for the activists to abandon the tent encampment Monday afternoon or be suspended.Instead, protesters defied the ultimatum and took over Hamilton Hall early Tuesday, carrying in furniture and metal barricades.Ilana Lewkovitch, a self-described 맥스카지노�leftist Zionist맥스카지노� student at Columbia, said it맥스카지노�s been hard to concentrate on school for weeks. Her exams have been disrupted with chants of 맥스카지노�say it loud, say it clear, we want Zionists out of here.맥스카지노�Lewkovitch, who is Jewish, said she wished the current pro-Palestinian protests were more open to people like her who criticize Israel맥스카지노�s war policies but believe there should be an Israeli state.
