Dozens arrested in weekend of protests on U.S. campuses

Police on Saturday arrested at least 25 pro-Palestinian protesters and cleared an encampment at the University of Virginia, the university said in a statement, as U.S. campuses braced for more turmoil during graduation celebrations.

Tensions flared at UVA's campus in Charlottesville, where protests had been largely peaceful until Saturday morning, when police officers in riot gear were seen in a video moving on an encampment on the campus' lawn, cuffing some demonstrators with zip-ties and using what appeared to be chemical spray.

Students across the U.S. have rallied or set up tents at dozens of universities to protest the months-long war in Gaza and call on President Joe Biden, who has supported Israel, to do more to stop the bloodshed in Gaza. They also demand their schools divest from companies that support Israel's government, such as arms suppliers.

The University of Virginia said in a news release that protesters had violated several university policies including setting up tents on Friday night and using amplified sound.

Jim Ryan, UVA's president, wrote in a message that officials had learned that "individuals unaffiliated with the university" who presented "some safety concerns" had joined protesters on campus.

It wasn't immediately clear how many of those arrested were UVA students.

A group called UVA Encampment for Gaza that said earlier this week it had set up the encampment condemned the university's decision to call in police in a post on Instagram.

Dozens of people were arrested for criminal trespass outside the Art Institute of Chicago at a demonstration on Saturday after the institute called in police to remove protesters it said were illegally occupying its property, the Chicago Police Department said on
