Anti-Israel protesters and University of California, Los Angeles, police officers clashed on Monday after protesters set up an encampment at the school’s campus. It was the third such encampment at UCLA in the last several weeks.

“The protesters set up tents and barricades on the western end of Dickson Plaza around 3:15 p.m.,” the Daily Bruin reported. “Organizations including Students for Justice in Palestine at UCLA previously called on protesters to rally in Bruin Plaza at 2 p.m. before marching around campus.”
