BERKELEY, CALIF: A melee erupted on Saturday in a Berkeley, California park where supporters and opponents of President Donald Trump were holding competing rallies, resulting in at least 20 arrests as police struggled to keep the two camps apart.
As fist fights broke out between the two sides and people threw bottles and cans over a barricade separating them, police resorted to using to an explosive device at one point in a bid to restore order.
Several people were observed by a Reuters reporter with bloodied faces and minor injuries, but there was no official word on casualties from authorities. Media, citing police, reported that at least 11 people were injured.
Police said more arrests could follow after video shot during the melee was reviewed.
The trouble unfolded when hundreds of Trump opponents staged a counter-rally alongside an event billed as a “Patriots Day” free-speech rally and picnic, organized by mostly Trump supporters.
