Protesters angered by the federal detainment of migrants at the US-Mexico border blocked access to the Immigration and Customs Enforcement headquarters in Washington, D.C., and staged a sit-in.
News outlets reports at least 10 sit-in demonstrators were arrested and charged with unlawful entry.
Dozens marched from the National Mall to the agency's site around lunch time Tuesday, stopping federal workers from returning to their desks.
The demonstration went on for hours as attendees sang and carried signs saying "Never again is now" and "Never again means close the concentration camps."
