Police made more than 30 arrests as a pro-Palestinian tent encampment was dismantled at the University of Pennsylvania’s campus in Philadelphia, while another at the Massachusetts Institute of Technology was also removed. The dismantling at Penn came around 5:30 a.m., as campus and Philadelphia police moved in to remove protesters from the encampment that had been in place for more than two weeks. School officials said protesters were given warnings and the chance to leave without being detained. About 33 people, including students and faculty members, were among those arrested without incident and charged with defiant trespass, the school said. Tensions have ratcheted up in standoffs with protesters on campuses across the United States and in Europe.
