It took hours to bring the situation under control, as pro-Israeli assailants broke into a pro-Palestinian camp.

The office of California’s governor has criticised the police response to violence on campus at the University of California, Los Angeles.

A masked pro-Israeli group assaulted a pro-Palestinian student camp, before officers were called to the campus.

Governor Gavin Newsom’s spokesperson said the “limited and delayed” police intervention was “unacceptable”.

On Wednesday, state troopers arrested 17 anti-war protesters at the University of Texas at Dallas, said the BBC’s Tom Bateman on campus, while the NYPD arrested at least 15 people at Fordham University in the Bronx.
