Pro-Palestinian demonstrators at Columbia University took over a campus building at the New York university early Tuesday.
The school administration has urged students and staff to stay away from campus for the day.
The Pro-Palestinian protests escalated after demonstrators occupied an academic building called Hamilton Hall, barricading themselves inside.
According to the BBC, the Pro-Palestinian protesters said they did so in honour of Hind Rajab, a six-year-old girl found dead in Gaza earlier this year.
Columbia has urged students and staff to stay away from campus on Tuesday.
It began suspending student protestors who defied a deadline of 14:00 EST on Monday to leave their two-week encampment, though dozens of students remain at the site.
