Los Angeles police say they have made "mass arrests" after a fifth day of protests over US President Donald Trump's immigration raids.
Mayor Karen Bass declared an overnight curfew within a relatively small area of the city's downtown district, saying businesses were being vandalised and looted.
Elsewhere, the immigration raids that triggered the protests last Friday have continued, with deployed National Guard troops now protecting border control agents on enforcement operations.
Trump's row with state officials ramped up after he deployed troops to LA. The president has now vowed to "liberate" the city, but has been accused by California Governor Gavin Newsom of an "assault" on democracy.
On Tuesday, Trump defended his decision to send 4,000 National Guard troops and 700 Marines, saying it was to prevent the city being "conquered by a foreign enemy".
These troops lack the authority to make arrests, and have instead been tasked only with protecting federal property and personnel.
Newsom hit back at the president: "He again chose escalation; he chose more force." The California governor, who is seen as a potential presidential contender for the Democratic Party, warned that "other states are next".
The Los Angeles Police Department (LAPD) later said "multiple groups" were still congregating in the district.
The order affects an area of about one square mile in America's second-largest city.
LA's mayor said 23 businesses had been looted on Monday night, though she did not provide an estimate of financial losses to the city from the at-times violent disorder.
