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.

The parade is expected to include about 6,600 soldiers, 50 helicopters and 60-ton M1 Abrams battle tanks, as well as possibly 200,000 attendees and heightened security to match.

A flagship "No Kings" march and rally are planned in Philadelphia, but no events are scheduled to take place in Washington, D.C., where the military parade will take place on Trump's 79th birthday. Organizers of the protests say they want to take attention away from the parade.

"No Kings" protests have been organized nationwide in response to a massive military parade in Washington, D.C.
