Columbia University threatens to expel student protesters

Dozens of protesters took over a building at Columbia University on Tuesday, barricading entrances and unfurling a Palestinian flag from a window in an escalation of demonstrations against the Israel-Hamas war on college campuses nationwide. The school promised they would face expulsion.
The occupation at the campus in New York – where protesters had shrugged off an earlier ultimatum to abandon a tent encampment Monday or be suspended – unfolded as other universities stepped up efforts to end the protests. Police swept through some campuses, leading to confrontations and arrests. In rarer instances, university officials and protest leaders struck agreements to restrict the disruption to campus life.
