Mayor Karen Bass said Sunday that Los Angeles does not need National Guard troops to bolster city police amid protests against raids by Immigration and Customs Enforcement agents, despite violent incidents.

To some Angelenos, the notion that their city was being invaded by Mexico might sound like a fantastical twist on the history of U.S.-Mexico military relations.

With the downtown facing an 8 p.m. curfew, the Los Angeles police began using tear gas and crowd-control munitions to break up protests after issuing a dispersal order.
