NEW YORK − Protests loomed and negotiations inched forward Tuesday at NYU, Columbia and elsewhere as colleges across the nation grappled with unrest after days of demonstrations, campus closures and arrests swirling around U.

In one high-profile instance at Columbia University in New York, more than 100 students were arrested Thursday.

Columbia University has extended remote classes at its main New York City campus for the rest of term amid tense Gaza war protests that have spread to US colleges nationwide. The hybrid learning comes as some students have reported antisemitic harassment around Columbia's campus.
