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.

Some 133 were arrested on Monday in protests at New York University.

Dozens of arrests were also made in rallies at Yale, while Harvard has restricted access to the campus
