CBRN event in United States of America on Mon 30th March 2026

Authorities in Los Angeles deployed tear gas near a federal detention center and made dozens of arrests following one of thousands of “No Kings” rallies held this weekend across the United States and in Europe to protest President Donald Trump’s actions and the war in Iran. Los Angeles police said Sunday that 74 people were arrested for failing to heed a dispersal order that was given after Saturday’s rally ended. One other person was taken into custody on suspicion of possessing a weapon that police described as a dagger. The arrests stood out from what otherwise were mostly peaceful protests. Organizers said there were more than 3,100 events registered in all 50 U.S. states. Portland police made just three arrests Saturday at a U.S. Immigration and Customs Enforcement facility that has been a flashpoint between federal agents and protesters in the city. A few hundred gathered at the facility to protest following “No Kings” rallies that drew thousands to Portland’s city core, but the scene outside the facility was muted for most of the evening in comparison to clashes after earlier events. Portland police declared a riot at the facility after a “No Kings” protest last June and federal agents deployed tear gas against anti-ICE protesters following marches in both June and October. In downtown Los Angeles, hundreds of protesters surrounded a federal complex and some threw rocks, bottles and broken concrete blocks at officers, the U.S. Department of Homeland Security said in a statement late Saturday night. Two officers who were struck by concrete blocks sustained undetermined injuries and received medical attention, DHS said. Andre Andrews Jr., a Navy veteran and independent journalist, had walked the entire route of the Los Angeles rally and captured video of the event. He said after authorities gave the dispersal order, they deployed tear-gas canisters when protesters didn’t comply. Some protesters wearing shields and gas masks on the other side of a fence at the federal complex picked up the canisters and tossed them back at police. Andrews said some people also smashed concrete barriers into smaller pieces and threw them at authorities. “Does it make L.A. look bad? No. They’re bad actors causing problems, for sure,” Andrews said. “The peaceful protest was good for the cause. You have the right to do that. But the other people, they were definitely causing problems.” Police said those arrested included eight juveniles. Also detained was a woman dressed as the Statue of Liberty, smiling as she chatted with an officer who led her away. In Denver, the police department said on the social platform X that it declared an unlawful assembly and deployed smoke canisters after a small group of protesters blocked a road and did not leave as asked. At least eight people were arrested, as was a ninth person later who police said was throwing objects. Nationwide, people rallied from New York City, with almost 8.5 million residents in a solidly blue state, to Driggs, a town of fewer than 2,000 people in eastern Idaho, a state Trump carried with 66% of the vote in 2024. In Minnesota, a flagship event on the Capitol lawn in St. Paul drew Bruce Springsteen as its headliner to celebrate resistance to Trump’s aggressive immigration enforcement. Demonstrations also were held in more than a dozen other countries, according to co-executive director Ezra Levin of Indivisible, which spearheaded the events. U.S. organizers have estimated that the first two rounds of No Kings rallies drew more than 5 million people in June and 7 million in October. Levin estimated at least 8 million participants showed up Saturday. “It was powerful. It was historic. It was joyful. It was boisterous,” Levin said Sunday. “I’d say it went pretty well.”
