The detention of a 5-year-old boy by US federal immigration agents has sparked widespread anger in the Minneapolis area after the child was taken into custody with his father earlier this week, according to school officials.

Two firefighters preparing to battle a massive blaze in Washington state were detained by U.S. Border Patrol agents, who said they were in the country illegally. The arrests, which came as crews were about to join efforts against the 9,000-acre (3,600-hectare) Bear Gulch Fire on the Olympic Peninsula, have sparked criticism over immigration enforcement at the site of an active emergency.

A new bill introduced by Democratic Senators Alex Padilla (CA) and Cory Booker (NJ) would require federal immigration agents to wear visible identification and ban most face coverings during public enforcement operations.
