On Wednesday, US attorney Bill Essayli announced that two men had been arrested for allegedly throwing Molotov cocktails at law enforcement officers.

He said that both incidents happened on Saturday - one in Paramount, and one in downtown Los Angeles.

He added that federal authorities were looking at "hundreds of people" who allegedly engaged in violence during the protests in LA, saying they were prepared to make more arrests in the coming days.

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 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.

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.

On Wednesday, Defense Secretary Pete Hegseth backed Trump's move, telling a Senate hearing that sending the troops to Los Angeles was "lawful and constitutional".

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".

After the LA curfew came into force at 20:00 local time on Tuesday (03:00 GMT on Wednesday), police moved through downtown areas, firing rubber bullets to try to disperse crowds.

Explaining the curfew, Bass said she wanted "to stop the vandalism, to stop the looting". She added: "We reached a tipping point."

The Los Angeles Police Department (LAPD) later said "multiple groups" were still congregating in the district. Before the curfew came into effect, LA police chief Jim McDonnell said 197 people had been arrested on Tuesday. The majority of arrests since the protests began have been for failing to disperse.

The curfew order affects an area of about one square mile in the second-largest city in the US. McDonnell said the order was not impacting other parts of the city.

"Some of the imagery of the protests and the violence gives the appearance as though this is a city-wide crisis, and it is not."

Chaotic protests also sprung up on Tuesday in several other US cities:

• In Atlanta, Georgia, riot police used tear gas on protesters who set off fireworks towards officers at a demonstration attended by hundreds
• Police in New York told the BBC dozens were arrested for blocking vehicular traffic after several thousand marched into lower Manhattan
• Texas Governor Greg Abbott sent National Guard troops to San Antonio, where immigration rallies are planned

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.

Elsewhere in the sprawling city, it was a normal Tuesday. Tens of thousands of children went to school, commuter traffic choked the streets and tourists strolled Hollywood Boulevard.

Police chief Jim McDonnell said the curfew was "not about silencing voices", but was a necessary measure to save lives and safeguard property.

Bass also said Immigration and Customs Enforcement (ICE) had provoked the unrest by conducting raids on Latino areas in the city in recent days.

"If [the raids are] going to go on for 30 days, and that's what the rumour is, and, if we want to see our city peaceful again, I will call upon the administration one more time to end the raids," she said.

National Guard troops, who were previously guarding federal buildings, began assisting ICE agents with their "daily enforcement operations" on Tuesday, a spokesperson for the border agency told the BBC.

Marines were also guarding federal officials and property, Marines Corps General Eric Smith said. They do not have the authority to arrest.

The military deployment to the LA area will cost $134m (£99m), the Pentagon said.

Trump described the protests as a "full-blown assault on peace and public order" while addressing troops at the Fort Bragg military base in North Carolina.

The Republican president said he plans to use "every asset at our disposal to quell the violence".

Meanwhile, Trump's political row with state officials has intensified. The president has described the protesters as "animals" and vowed that "this anarchy will not stand".

He urged troops to boo the names of Newsom and Joe Biden, his presidential predecessor, during his Fort Bragg speech.

In televised remarks of his own on Tuesday night, Newsom again criticised the president's rare deployment of the US military without a request from state officials. He accused Trump of a "brazen abuse of power".

"California may be first – but it clearly won't end here," he said. "Other states are next. Democracy is next. Democracy is under assault right before our eyes."

Earlier in the day, a federal court denied an emergency request from California to block the use of troops sent to LA.

District Judge Charles Breyer scheduled a hearing on the motion for Thursday.

Trump has set a goal for border agents of at least 3,000 daily arrests as he seeks to ramp up mass deportations, a signature pledge of his re-election campaign.

Since assuming office, the president has drastically reduced illegal crossings at the US-Mexico border to historically low levels.

A CBS News/YouGov poll conducted in early June, before the protests kicked off, found 54% of Americans saying they approved of Trump's deportation policy, and 50% approved of how he was handling immigration.

That compares with smaller numbers of 42% who gave approval to his economic policy and 39% for his policy on tackling inflation.
