"Physical altercations" occurred Sunday on the UCLA campus when demonstrators breached a security barrier set up to keep people protesting the Israeli war in Gaza separate from counterprotesters, the school said in a statement.
The clash came one day after arrests on at least four universities as demonstrations and days-long encampments in opposition to the war swept across the nation's college campuses. Students are calling for a cease-fire and want their schools to stop investing in Israeli firms that are involved with or profit from Israel's war against Hamas.
The protesters also want the U.S. to halt military aid to Israel's war effort.
“UCLA has a long history of being a place of peaceful protest, and we are heartbroken about the violence that broke out,” the school's vice chancellor for strategic communications, Mary Osako, said in a statement.
