Protests against the war in Gaza have spread from Columbia and Yale to other US universities as officials scramble to defuse demonstrations.
On Monday night, police moved to break up a protest at New York University and made a number of arrests.
Dozens of students were arrested at Yale earlier in the day, while Columbia cancelled in-person classes.
Similar “encampments” have sprung up at Berkeley, MIT and other top colleges across the country.
Demonstrations and heated debates about the Israel-Gaza war and free speech have rocked US campuses since the Hamas attack on Israel on 7 October, which prompted Israel’s campaign in Gaza.
