The University of Southern California announced on Thursday that it has canceled its main-stage graduation ceremony for students, a move that follows campus protests over the Israel-Hamas war and a controversy over its selection of a class valedictorian.

The university said that it could not host the ceremony, which was scheduled for May 10, because of new safety measures that would have increased the amount of time needed on the day to process the 65,000 students and guests who usually attend.

This week, the university has been rocked by turmoil by pro-Palestinian protesters, resulting in the arrests of more than 90 people.
