Violence flares at UCLA as police end protests at New York's Columbia

LOS ANGELES/NEW YORK, May 1 (Reuters) - Mounting tensions on U.S. campuses boiled over on Wednesday when pro-Israel supporters attacked an encampment of pro-Palestinian protesters at UCLA, hours after police arrested activists who occupied a building at Columbia University and flattened a tent city on its campus.

Eyewitness videos from UCLA, verified by Reuters, showed people wielding sticks or poles to hammer on wooden boards being used as makeshift barricades to protect the pro-Palestinian protesters before police were called to the campus.

On the other side of the country, scores of New York City police officers in helmets and armor arrested pro-Palestinian demonstrators occupying an academic building at Columbia University. Undergraduate students out watching the extraordinary scene, many jeering at the police, fled into nearby buildings on the command of officers as police also cleared out a nearby protest encampment that had inspired similar protests at campuses across the country and abroad.

Police arrested about 300 people at Columbia and City College of New York, Mayor Eric Adams said. Many of those arrested were charged with trespassing and criminal mischief.

The clashes at UCLA and in New York are part of the biggest outpouring of U.S. student activism since the anti-racism rallies and marches of 2020. The protests follow the Oct. 7 attack on southern Israel by Hamas militants from the Gaza Strip and the ensuing Israeli offensive on the Palestinian enclave.

Students have rallied or set up tent encampments at dozens of schools across the U.S. in recent days, expressing opposition to Israel's war in Gaza and demanding schools divest from companies that support Israel's government. Many of the schools have called in police to quell the protests.

With thepresidential election coming in November, Republican lawmakers have accused some university administrators of ignoring antisemitic rhetoric and harassment, and some have demanded Columbia's President Minouche Shafik resign.

Many protesters, some of whom are Jewish, reject allegations of antisemitism. Shafik has said the protests have brought rancor to life at Columbia, while also blaming some episodes of harassment and hostile rhetoric on outsiders drawn to the busy Manhattan streets surrounding the campus.

U.S. President Joe Biden, who has angered many protesters by funding and arming Israel, plans to give a speech on antisemitism next week at a Holocaust memorial event.

"Americans have the right to peacefully protest," Karine Jean-Pierre, the White House spokesperson, told reporters. "Forcibly taking over a building is not peaceful."

Before the clashes in Los Angeles, UCLA officials declared that an encampment on its campus was unlawful, violated university policy and included people unaffiliated with the campus.

Afterwards, counter-demonstrators - many of them masked and some apparently older than most students - can be seen in videos throwing objects and trying to smash or pull down the wooden and steel barriers erected to shield the encampment.

Some screamed pro-Jewish comments as pro-Palestinian protesters tried to fight them off.

"I just didn't think they would ever get to this," said Kaia Shah, a pro-Palestinian protester and researcher at UCLA, "where our protest is met by counter-protesters who are violently hurting us, inflicting pain on us, when we are not doing anything to them."

Demonstrators on both sides used pepper spray, and fights broke out. Pro-Palestinian demonstrators said the counter-protesters threw fireworks at them and beat them with bats and sticks.

Benjamin Kersten, a UCLA graduate student and member of the pro-Palestinian group Jewish Voice for Peace, called it "a devastating night of violence."

"The encampment would be a peaceful effort were it not for the continuous presence of counter-protesters and agitators," he wrote in a text message.

"While Congress holds more hearings on whether Jewish students feel safe enough on campuses, Jewish students are among those withstanding attacks from Zionist protesters," he said in reference to recent sessions held by a Republican-led House of Representatives committee.

Police said UCLA had called them to restore order and maintain public safety "due to multiple acts of violence" within the encampment. Broadcast footage later showed police clearing a central quad beside the encampment and erecting a metal crowd control barrier in front of it.

The atmosphere was calmer on Wednesday. Hundreds of police officers were on campus and lining its perimeter. It was unclear how many arrests were made or the number of people injured.

Columbia's Shafik said she had asked police to stay on campus until at least May 17, two days after graduation, and the main campus, where student dorms are located, remained under lockdown on Wednesday. The school said the rest of the semester would be conducted remotely, including final exams, some of which may be delayed.

Ararat Sekeryan, a sixth-year Slavic languages doctoral student from Istanbul, described being pushed out of the lawn encampment and described the calling of police as dangerous.

"I myself felt attacked," he said. "They were so afraid of this peaceful movement that they had to send more than a thousand, maybe hundreds of police to campus."

Ben Solomon, a 22-year-old Jewish student at Columbia, said he welcomed the move to clear what he called a "mob" from the occupied building and encampment.

"I'm glad to see universities took decisive action," he said, as more than 100 students and professors gathered in a street adjoining the campus to protest the school's decision to call the police.

Shafik said the events filled her "with deep sadness."

"I am sorry we reached this point," she wrote in an email to the university community on Wednesday, promising efforts to reunite a frayed campus.

The university earlier warned that students taking part in the occupation faced academic expulsion.
