Stanford University said 13 people were arrested as law enforcement removed pro-Palestinian demonstrators who had occupied a campus building early Wednesday, June 5, that houses the university president and provost offices, with the school saying there was extensive damage inside and outside the building.

The takeover began near dawn on the last day of classes for the spring quarter.

A few protesters barricaded themselves inside while other linked arms outside, The Stanford Daily reported.

The group chanted "Palestine will be free, we will free Palestine".

The student newspaper said one of its reporters was among those detained.

Within about two hours officers had broken into the building and began taking people into custody.

"Law enforcement has arrested 13 individuals, and the building has been cleared," university spokesperson Dee Mostofi said in an email to the Associated Press.

"There has been extensive damage to the interior and exterior of the building," Mostofi said.

No other campus operations have been affected at this time.

Stanford is among colleges and universities around the country where campus protests have occurred to demand their schools separate themselves from companies advancing Israel's war against Hamas in Gaza and in some cases from Israel itself.

Columbia University agreed to take additional steps to make students feel secure on campus under a settlement reached with a Jewish student.
