Pro-Palestinian encampments have emerged on other campuses, including at the University of Michigan, New York University, and MIT. : Columbia canceled in-person classes, dozens of protesters were arrested at Yale and the gates to Harvard Yard were closed to the public on Monday as some of the most prestigious U.S. universities sought to diffuse campus tensions over Israel’s war with Hamas. The various actions followed the arrest last week of more than 100 pro-Palestinian demonstrators who had camped out on Columbia’s green, as schools struggle with where to draw the line between allowing free expression while maintaining a safe and inclusive campus.
