NEW YORK (NewsNation) — Pro-Palestinian supporters at Columbia University face a looming deadline to dismantle their encampment as protests intensify across New York City and the nation.

Protesters have until Friday to remove their encampment. The university, however, has already backtracked on previous deadlines, which included one Tuesday.

“We have our demands; they have theirs,” said Columbia spokesperson Ben Chang.

Columbia officials said negotiations were showing progress as the school’s self-imposed early Friday deadline to reach an agreement on dismantling the encampment came and went. Nevertheless, two police buses were parked nearby, and there was a noticeable presence of private security and police at entrances to the campus.

The students are calling for universities to separate themselves from any companies that are advancing Israel’s military efforts in Gaza — and, in some cases, from Israel itself.
