Duelling groups of protesters clashed on Wednesday at the University of California, Los Angeles, grappling in fistfights and shoving, kicking and using sticks to beat one another.
Hours earlier, police carrying riot shields burst into a building at Columbia University that pro-Palestinian protesters took over and broke up a
demonstration that had paralysed the school while inspiring others.
After a couple hours of one-and-off scuffles between pro-Palestinian and pro-Israeli demonstrators at UCLA, police wearing helmets and face shields arrived, formed lines and began to slowly corral some of the protesters. That appeared to quell the violence.
