Columbia University has suspended more than 65 students for their role in a pro-Palestinian demonstration that forced the shutdown of the main campus library, a school official said on Friday. The students were placed on interim suspension and will be prohibited from taking their final exams or entering campus except to access their dormitories,

Columbia University has suspended dozens of students and barred alums and others who participated in a pro-Palestinian demonstration inside the school’s main library earlier this week.

Columbia students reported feeling threatened when masked protesters stormed the campus library, chanted anti-Israel slogans, and mocked the Israeli hostage crisis.
