Thousands of people protesting mass deportations planned by President Donald Trump marched in Southern California, including in downtown Los Angeles where demonstrators blocked a major freeway.

A large crowd gathered in downtown Los Angeles on Sunday in response to the recent increase in ICE raids and deportations. The gathering briefly closed the 101 Freeway, which led to police declaring an unlawful assembly and forcing demonstrators to disperse during the daylong event.

Thousands, many with Mexican flags and signs containing phrases such as “Viva Mexico” and “Nobody is illegal,” participated in the protest in Los Angeles.
