Hundreds policemen have invaded the University of California in Los Angeles (UCLA) and dismantled tents set up by students, and pro-Palestinian protesters were arrested.
The pre-dawn police raid on the university is the latest flashpoint in tensions on American college campuses, where protests over Israel's war in Gaza have led students to clash with each other and with law enforcement, Voice of America reports.
The police action came 24 hours after the conflict on campus, which began when a group of pro-Israel protesters attacked a pro-Palestinian camp.
Police detained a small group of protesters on campus today, and the action came after officers threatened arrests over loudspeakers for hours if people did not disperse.
Hundreds of people gathered on campus, both inside the barricaded tent camp and outside it in support.
As police helicopters flew overhead, the sound of stun bombs, which produce bright lights and loud noises to disorient and stun people, ripped through the air.
"You want peace, we want justice"
Police officers wore helmets, protective vests and batons, and some of the demonstrators had gas masks, while others shouted: "You want peace, we want justice."
Police methodically removed barricades made of plywood, pellets, metal fences and garbage containers to reach dozens of tents.
The protest at UCLA is one of many pro-Palestinian demonstrations on college campuses across the country that have resulted in hundreds of arrests.
New Hampshire police arrested protesters and removed tents late Wednesday and early Thursday morning at Dartmouth College.
A pro-Palestinian protest camp was organized at Dartmouth on Wednesday after university officials warned that such a camp would be a violation of university policy.
Two students were arrested in Dartmouth in October after erecting a tent as part of a protest calling for a fence from Israel.
A group of Dartmouth students later went on hunger strike to protest the arrests, and a campus solidarity rally for Gaza last week drew more than 100 people.
Police actions in many cities
At the University of Texas at Dallas, police cleared a pro-Palestinian camp after arresting at least 17 people.
In New York, police arrested at least 15 people Wednesday at Fordham University as they dispersed participants at a pro-Palestinian protest camp.
At the University of Minnesota, protest organizers said their sit-in would continue after speaking with the university's interim president, Jeff Ettinger, earlier in the day. As with many colleges, protesters are calling for the university to distance itself from Israel, and Ettinger described the talks as "constructive dialogue."
Columbia University announced Wednesday that all remaining academic activities for the coming semester will be held remotely, following protests that included the occupation of a campus building. On Tuesday night, the police dispersed the protesters and arrested almost 300 people.
