Thousands of people braved icy conditions on Friday to protest the U.S. government's immigration crackdown in Minneapolis and businesses closed their doors amid anger over the detention of a 5-year-old migrant boy.

Dozens of eateries, attraction sites and other businesses shuttered as part of a day of coordinated action to defy the weekslong federal immigration operation underway in Minnesota.

Images of an apparently terrified pre-schooler, Liam Conejo Ramos, being held by immigration officers who were seeking to arrest the boy's father have rekindled public outrage at the federal crackdown, during which an agent shot and killed a U.S. citizen.
