Patience has run out for the authorities cracking down on student protests across the United States. 

Pro-Palestinian protests at multiple colleges have broken out into violence and property destruction.  

US correspondent Mitch McCann told Mike Hosking that police were called to clear out students in New York’s Columbia University. 

He says up to 300 people were arrested as a result. 

This morning there have been violent clashes between pro-Palestine and pro-Israel demonstrators at UCLA, with reports of fireworks, projectiles, and physical violence.
