680 immigrants were arrested Wednesday by U.S. Immigration and Customs Enforcement (ICE) agents at 7 food processing plants in small towns in Mississippi, the AP reports.

Why it matters: ICE Acting Director Matthew Albence said these could be the largest workplace raids ICE has had in more than a decade, and likely the biggest for any single state, per the AP. This comes just a few weeks after ICE raids that reportedly targeted thousands of immigrants resulted in just 35 arrests. ICE detention facilities still hold thousands more migrants than Congress has approved funding for.
