The US state of Minnesota has sued the Trump administration in an attempt to block a surge of federal immigration agents into the state.

The lawsuit argues that the deployment amounts to an unconstitutional "federal invasion". Minnesota's Attorney General Keith Ellison said it has upended life for millions of people and caused "chaos and violence".

It comes after the death of Renee Good, who was shot dead by an immigration agent last week triggering large protests.

The lawsuit asks a federal court to declare the deployment illegal. The Trump administration has said the agents are targeting undocumented migrants, and further agents are needed to ensure their safety.
