PORTLAND, Ore. (AP) Authorities in Oregon have launched an investigation on assaults during a Portland street brawl that erupted this weekend between demonstrators with a right-wing group and left-wing counter-protesters.
Media outlets reported no immediate arrests following the clash Saturday.
Portland police said in a statement they were investigating and seeking help from witnesses, as well as reviewing video and photos.
KGW-TV reported four people received medical attention, but authorities did not know if anyone was taken to hospitals.
Police say officers saw people at the demonstration with hard-knuckled gloves, guns, knives and batons.
The right-wing Patriot Prayer group was holding a "Flash March for Law and Order" when the counter-demonstrators arrived and scuffles broke out.
This version corrects that the brawl happened Saturday, not Sunday.
