Columbia University has backed off from an overnight deadline for pro-Palestinian protesters to abandon an encampment there as more college campuses in the United States sought to prevent occupations from taking hold, AFP reports.

The office of New York-based Columbia University president Minouche Shafik issued a statement at 11:07 pm (0307 GMT Friday) retreating from a midnight deadline to dismantle a large tent camp with around 200 students.

“The talks have shown progress and are continuing as planned,” the statement said. “We have our demands; they have theirs.”

The statement denied that New York City police were invited on the campus. “This rumor is false,” it said.

A student, identifying herself only as Mimi, told AFP she had been at the camp for seven days.

“They call us terrorists, they call us violent. But the only tool we actually have are our voices,” she said.
