ICE to conduct major immigration operations in three cities per week

Federal enforcement agencies are targeting three U.S. cities per week for large scale immigration arrests, with Aurora, Colorado to come next, three sources familiar with the planning told NBC News.

So far this week, Immigration and Customs Enforcement agents, along with other federal law enforcement agencies, have focused arrests in Chicago, in an operation that began Sunday, and New York City, where arrests began Tuesday. Those efforts will next shift to Aurora, Colorado, for an operation beginning early Thursday morning, the sources said.
