Federal agents detained at least 350 immigrant workers in Laurel, Mississippi Monday in one of the largest immigration raids in US history. Agents from Immigration and Customs Enforcement descended on the Howard Industries factory early on Monday and separated all Latino workers from their white and black co-workers. By afternoon, several dozen family members of immigrants waited for news of their relatives at a local Catholic Church. Federal agents have carried out a series of large immigration raids in recent months. In May, over 400 workers at a kosher meatpacking plant were detained in Postville, Iowa. Two weeks ago, forty-two immigrant workers were picked up at Dulles International Airport.
