Thousands of troops and hundreds of US Marines have been deployed to the city by US President Donald Trump to quell the demonstrations. Nearly 400 people have so far been arrested, including 330 undocumented migrants and 157 people arrested for assault and obstruction, including one for the attempted murder of a police officer.

On Tuesday, the X page for U.S. Immigration and Customs Enforcement (ICE) posted photos of California National Guardsmen on the scene of a detention being carried out by an ICE agent with the caption "Photos from today's ICE Los Angeles immigration enforcement operation."

The California Governor has sued the U.S. President over the mobilization of the National Guard, calling it “an unmistakable step toward authoritarianism.”

The Guard’s arrival marks a potentially volatile phase in Trump’s push to ramp up deportations and in his contentious relationship with state and local authorities.
