Police say 13 people have been arrested as pro and anti-Trump demonstrators clashed in Berkeley Saturday. Two simultaneous demonstrations were planned for Civic Center Park. The demonstration has since taken over Center Street and Allston Way between Milvia Street and Martin Luther King Jr. Way. The downtown Berkeley BART station has also closed as a result.

Police say a large number of fights have occurred and numerous fireworks have been thrown in the crowds. There have also been numerous reports of pepper spray being used in the crowd. Photos from the scene Saturday morning showed police dressed in riot gear. In anticipation of the event, police had already informed demonstrators about a long list of items that were banned from the event, such as metal pipes, baseball bats, poles and bricks. READ MORE
