Israel, Gaza and divestment: what we know about the Columbia student protests

The university is to hold virtual classes after protests on campus culminated in the arrest of more than 100 students

Over 100 students at Columbia were arrested last week after refusing to leave a pro-Palestine protest encampment set up on the university's main campus. The arrests have since set off a chain of events, including the re-establishing of the encampment and solidarity protests on other US college campuses.

On Monday, Columbia announced it will hold classes virtually to try to reset" the situation on campus. Here's what we know so far about what's happening at Columbia.
