Police forcibly removed scores of defiant pro-Palestinian protesters at several colleges on Thursday, including taking down an encampment at UCLA in a jarring scene that underscored the heightened chaos that has erupted at universities this week, Reuters reports.

In the pre-dawn hours, helmeted police swarmed a tent city set up at the University of California in Los Angeles, using flash bangs and riot gear to push through lines of protesters who linked arms in a futile attempt to halt their advance.

Los Angeles police said on social media that 210 people were arrested at UCLA, and hundreds of arrests were made at other universities overnight and on Thursday.

“I’m a student here,” one UCLA protester told cameras as he was led away, his hands bound. “Please don’t fail us. Don’t fail us.” Hours later, the student, who would only give his first name as Ryan, was back on campus and vowed he would not stop fighting.

“We will be back,” said Ryan, who was cited for unlawful assembly. “We will be disrupting. We will be demanding divestment.” Students have rallied or set up tents at dozens of universities in recent days to protest Israel’s onslaught on Gaza.

Demonstrators have called on President Joe Biden, who has supported Israel’s right to defend itself, to do more to stop the bloodshed in Gaza and demanded schools divest from companies that support Israel’s government.
