Students taking part in a Gaza Solidarity Encampment on the campus of New York’s Columbia University say they have been threatened with arrest, Al Jazeera reports.

In a post on social media, the Columbia Students for Justice in Palestine said the New York Police Department has warned the protesting students that they face arrest for participating in the tent encampment on the main lawn of the university’s campus.

According to reports, the hundreds of protesting students have been given a deadline to vacate the solidarity camp by university staff and there is a large police presence that appears ready to intervene.
