More than 2,000 "No Kings Day" protests were held across US cities on Saturday to protest against the Trump administration and to counter the military parade in Washington, D.C., media reports said.

As per ABC News, more than 5 million people participated in these protests.

The demonstrations remained peaceful in almost all cities, except for Los Angeles, where tensions escalated between police and protesters in the evening.

The protest against the Immigration and Customs Enforcement raids, which started in LA last week, has now spread to other cities across the US, including New York City, San Francisco, Boston, and Austin, Texas.

As the protest escalated, a person was critically injured in a shooting "possibly associated" with a demonstration in downtown Salt Lake City, police said.

The shooting occurred near Salt Lake City's Pioneer Park, where a large crowd, estimated to be 10,000, had gathered for a march, according to reports.

"The shooting at tonight’s protest in Salt Lake City is a deeply troubling act of violence and has no place in our public square," Utah Gov. Spencer Cox said in a social media post. "This is an active situation, and we’re working closely with law enforcement to ensure accountability."

Meanwhile, ahead of the planned curfew at 8 p.m. local time, the Los Angeles Police Department asked all demonstrators to leave the Civic Center area of downtown LA.

Shortly before the request, the LAPD said officers had requested assistance due to "agitators" throwing objects at officers.

Earlier, a dispersal order had been issued for an area of downtown after the LAPD said people in the crowd were throwing rocks, bricks and bottles.
