Protests continued in Minneapolis and other US cities on Sunday over the fatal shooting by immigration agents of 37-year-old intensive care nurse Alex Pretti in Minneapolis on Saturday.

Minnesota Governor Tim Walz said America was at an inflection point and repeated calls for US President Donald Trump to remove federal immigration agents from the city.

The US president meanwhile called for the governor to turn over all Criminal Illegal Aliens incarcerated in state prisons for deportation.

Meanwhile Minneapolis Police Chief Brian O'Hara told the BBC that state officers were blocked from accessing the scene of the shooting by federal agents, despite securing a search warrant.

He added that all levels of law enforcement in Minnesota have been working with federal law enforcement for several years, and that the unfolding situation in Minnesota was hampering agencies' ability to continue such investigations.

US Border Patrol commander Greg Bovino on Saturday accused O'Hara and Frey of trying to derail federal law enforcement operations.

Trump signaled in an interview with the Wall Street Journal published on Sunday that he might be willing to eventually withdraw ICE agents from the Minneapolis area, but did not provide a time frame.

He said: At some point we will leave. We've done, they've done a phenomenal job. In the interview, the president added that his administration was reviewing everything about Pretti's death and said that it will come out with a determination.

Lawmakers continue to be divided over the shooting of Pretti, as well as his Second Amendment right to bear arms.

An eyewitness account and conflicting narratives challenge the Department of Homeland Security's assertion that the agents acted in self-defense, stirring public outrage and widespread calls for justice.

In Minneapolis, hundreds of people gathered in protest, waiving signs demanding accountability and an end to ICE's operations.

As political tensions heighten, prominent Minnesota businesses have called for de-escalation, emphasizing the need for collaboration among local and federal officials to address the ongoing crisis.
