The LAPD said on social media that the people in the crowd were throwing "rocks, bricks, bottles and other objects" while they were near the federal building.

With the downtown facing an 8 p.m. curfew, the Los Angeles police began using tear gas and crowd-control munitions to break up protests after issuing a dispersal order.

The largely peaceful protests during the "No Kings Day" demonstration in downtown Los Angeles took an intense turn in the afternoon. Police ordered the crowd to disperse at about 4:15 p.m. PDT near Alameda Street and Temple Avenue, according to the Los Angeles Police Department's Central Division.

Protesters filled streets in hundreds of cities across the US to oppose President Donald Trump’s administration on Saturday, as he held a military parade in Washington.

The demonstrations come on the heels of protests flaring up around the country over federal immigration enforcement raids that began last week and Trump ordering National Guard troops and Marines to Los Angeles where protesters blocked a freeway and set cars on fire.
