U.S. Immigration and Customs Enforcement has suspended its operations in the areas near the Northern California fire areas.
ICE said Friday that because of the devastation the fires are bringing to California, the agency will "suspend routine immigration enforcement operations in the areas affected" at places such as shelters, food banks, and evacuation sites.
According to ICE spokesman James Schwab, immigration enforcement will take place only "in the event of a serious criminal presenting a public safety threat."
