NEW YORK, NEW YORK - APRIL 30: Student Pro-Palestinian protestors chant near an entrance to Columbia University on April 30, 2024 in New York City. Columbia University has restricted access to the school's campus to students residing in residential buildings on campus and employees who provide essential services to campus buildings after protestors took over Hamilton Hall overnight renaming it as "Hind's Hall" in honor of Hind Rajab. The students have barricaded themselves in the building and have also erected another encampment on Lewisohn Lawn, outside Lewisohn Hall. The protesters have said they are planning to remain at the hall until the university concedes to CU Apartheid Divest’s three demands: divestment, financial transparency and amnesty.
