Police said they made six arrests as of 9 p.m., NBC News
reported, charging several individuals with multiple offenses including carrying firearms without a license, possession of unregistered ammunition and possession of an unregistered firearm. Some demonstrators were also charged with assaulting a police officer, the network reported.
Photos and videos taken near the city's newly minted Black Lives Matter plaza show police using pepper spray on demonstrators, some of whom are seen shoving officers and screaming at them.
Several people appeared to be injured or bleeding as a result of the clash just north of the White House grounds.
