New York CNN —Columbia University student organizers were given a midnight deadline Tuesday to resolve talks with the university over dismantling the pro-Palestinian encampment that has cast its campus into days of turmoil and unease, the school’s president said. Though the outcome of the negotiations is still unclear, Columbia President Minouche Shafik said the university would consider “alternative options” if no agreement was reached by midnight. As of 12:10 a.m., the NYPD had not been asked by Columbia University to respond to the campus, a police spokesperson told CNN. Harvard University has closed Harvard Yard and officials at the university suspended a pro-Palestinian student organization for allegedly violating school policies. The encampment at Columbia University was lively early this week, with many students congregating in circles, eating and talking.
