Marines are now on duty in Los Angeles for the first time.
Tensions are escalating between President Donald Trump and California Gov. Gavin Newsom as protests against Immigration and Customs Enforcement continue to grip Los Angeles and spread to New York City, San Francisco, Boston, Austin, Texas, and other cities.
Trump deployed about 4,000 National Guardsmen and 700 Marines to LA against Newsom's wishes.
A federal appeals court Thursday delayed an order requiring the Trump administration to return control of the National Guard to Newsom, dealing the administration a temporary reprieve to what would have been a major reversal of its policy on the protests.
Los Angeles Mayor Karen Bass took to X on Tuesday to say she's monitoring the ongoing protests in the downtown area and is "preparing to take new action to protect our communities."
It comes as local leaders have considered implementing a curfew in the area.
"Stay alert and be ready to follow any safety measures that may be announced soon," Bass said.
There have been over 300 people detained by Immigrations and Customs Enforcement in Los Angeles since Friday, according to the Coalition for Humane Immigrant Rights of Los Angeles, a local immigrant rights organization.
This comes as protests have rocked the city, sparked by ICE raids in downtown Los Angeles.
The organization says that figure is based on the number of reported enforcement actions.

Protests in downtown Los Angeles on Tuesday have now moved to block traffic on the 101 Freeway.
Officers on the scene are working to move demonstrators away from the major highway.
This comes after protesters blocked both northbound and southbound lanes of the 101 Freeway for several hours on Sunday night.
California Gov. Gavin Newsom said he’s filed an emergency motion to block President Donald Trump’s deployment of Marines and National Guardsmen, saying the president’s actions were illegal and are "turning the U.S. military against American citizens."
"The courts must immediately block these illegal actions," Newsom wrote on social media.
U.S. District Judge Charles Breyer has set a Thursday hearing to determine whether to issue a temporary restraining order.
He declined Newsom's request to issue the order immediately and is giving the Trump administration the time they requested to file a response.
