LOS ANGELES (AP) — About 90 members of the California National Guard and over dozen military vehicles like Humvees are helping protect immigration officers Monday as they carry out a raid in a Los Angeles park, defense officials said.

California National Guard soldiers arriving in Humvee military vehicles backed a Monday sweep of a park in a neighborhood of Los Angeles heavily populated by immigrants, according to L.A. Mayor Karen Bass.

Dozens of federal officers and about 90 members of the California National Guard were deployed to a mostly empty park in a L.A. neighborhood with a large immigrant population.
