Columbia University said on Tuesday it was disciplining dozens of pro-Palestinian student protesters who seized part of the school's main library during a demonstration in early May that led to multiple arrests.

Columbia was at the forefront of U.S. campus protests over the war in spring 2024. Pro-Palestinian demonstrators set up an encampment and seized a campus building in April, leading to dozens of arrests and inspiring a wave of similar protests nationally.

Columbia University has disciplined over 70 students for participating in two student-led protests, a source familiar with the matter said.
