Nationwide ICE protests live updates: Curfew in downtown LA for 2nd night

For the second night, a curfew is in effect for part of downtown Los Angeles that has been the site of protests and marches that have seen some clashes with authorities.

The curfew lasts until 6 a.m. local time.

LA Mayor Karen Bass said the nightly curfew, which first went into Tuesday, would likely remain in effect for multiple nights.

About a half hour before the curfew went into effect on Wednesday, the Los Angeles Police Department said a large demonstration at Grand Park in front of LA City Hall had splintered and was blocking streets in the Civic Center area.

Earlier, police said some protesters in a demonstration marching on Hill Street in downtown LA were throwing fireworks and rocks at officers.

About 700 Marines are still undergoing civil disturbance training at Naval Weapons Station Seal Beach in Orange County, said Maj. Gen. Scott Sherman, head of the task force that's overseeing the deployment of the National Guard and Marines to Los Angeles.

Sherman wouldn't speculate about when the Marines might join the 2,000 or so Guard troops that have been deployed in downtown areas to protect federal buildings during sometimes violent demonstrations against President Trump's immigration crackdown.

"Our mission is to protect federal agencies, our federal partners, their personnel, as they conduct their federal mission," Sherman said.

Another 2,000 Guard soldiers are on duty and stationed at Joint Forces Training Base in Los Alamitos.

With migrant communities already living in fear amid the Trump administration's immigration crackdown, ICE raids in downtown Los Angeles sparked days of protests.

Several people protesting ICE detentions were arrested in downtown Manhattan on Wednesday. Officers began detaining people after the protest, which started in Foley Square near City Hall, began moving down Broadway before being stopped by police at the intersection of Broadway and Duane.

The arrests appeared to take place after protesters did not clear a crosswalk when ordered to by police.

Hundreds of protesters remain in the area, chanting behind barriers, with dozens of officers standing by.
