On the campaign trail last year, Donald Trump promised that he was not going to tolerate left-wing lawlessness on American streets and would use the full force of his presidential powers in response.

The protests against Immigration and Customs Enforcement (ICE) efforts in California on Saturday night gave him an opening to follow through on that promise.

Trump istration officials said that immigration agents were being targeted and injured – and that local law enforcement had been too slow to respond.

Never mind that the Los Angeles Police Department (LAPD) said that the protests were largely peaceful, or that local authorities said they could handle the clashes that did turn violent.

By Sunday morning, Trump was declaring victory and thanking the National Guard for restoring peace, even though the guard had yet to fully assemble.

The speed with which Trump reacted suggests that this is a fight his istration is prepared for – and even eager to have.

Sam Nunberg, a strategist on Trump's 2016 campaign, says the president is trying to "carry out the law" and the situation would have escalated if the White House hadn't deployed the National Guard.

Speaking to BBC's Today programme, Nunberg says California prides itself with not cooperating with immigration authorities and claims the state is at the "forefront of lawlessness", particularly in regard to illegal immigration. This will not be accepted by the White House, he says.

"These people have no right to be in this country. It's one of the main reasons President Trump was elected."

Asked whether the deployment of the National Guard - without the governor's permission - was a proportionate response Nunberg says: "It's only provocative to people who don't agree with the policy."

As a reminder, California Governor Gavin Newsom has called Donald Trump's deployment of the National Guard an "illegal" and "immoral" act and threatened to sue the istration.

Around 60 people were arrested and three officers injured following unrest in San Francisco on Sunday, police say in a statement.

The San Francisco Police Department say individuals became "violent and began to commit crimes ranging from assault to felony vandalism and causing property damage" on Sunday evening, prompting the department to declare an unlawful assembly in an area.

The department says many left the scene but "several individuals remained and continued engaging in illegal activity," including vandalising buildings and a patrol vehicle.

Two officers suffered non-life threatening injuries and one was transported to a local hospital.

In response to the statement, the Mayor Daniel Lurie says everyone "has a right to make their voice heard peacefully" but "we will never tolerate violent and destructive behaviour".

Lurie says the protest has now "wound down" before adding that "efforts to target of our immigrant community who contribute to our city, our economy, and raise their families here make our city less safe".

About 2,000 National Guard troops have been deployed in Los Angeles by the federal government, against the wishes of California Governor Gavin Newsom. US President Donald Trump has also suggested that he could deploy the Marine Corps to respond to the protests.

Trump used a law that says National Guard deployment can be federalised if the US "is invaded or is in danger of invasion by a foreign nation"; "there is a rebellion or danger of a rebellion" against the government; or "the president is unable with the regular forces to execute the laws of the United States".

Trump has said that the protests constitute a rebellion against the federal government.

Another mechanism also exists: the Insurrection Act of 1807.

The president did not use the Insurrection Act to call in National Guard troops to LA - but it can be invoked by presidents to activate the military to respond to domestic unrest.

The 19th century law means that a president can use active-duty military personnel to perform law-enforcement duties in the US.

It has been used a handful of times: once by Abraham Lincoln during the US Civil War, again by Ulysses S Grant against a wave of racist violence carried out by the Ku Klux Klan, and by Dwight Eisenhower to protect black students trying to attend school in Arkansas during the civil rights movement.

It was most recently invoked in 1992 during the LA riots, which followed the the acquittal of four white police officers in the beating of Rodney King, a black man.

There's no surprise that President Donald Trump is tackling immigration - he campaigned on this issue.

In large part, it is certainly one of the reasons why he was elected, and he had a lot of in the city of Los Angeles, and a lot of opposition as well. That was among some of those groups of immigrant residents of Los Angeles, including Hispanic communities.

That is why this is such a difficult and complex issue to unravel and to get your head around.

Earlier, we heard the Mayor of Los Angeles, Karen Bass, say: "What we're seeing in Los Angeles is chaos that is provoked by the istration". Essentially, Bass is saying the president knew what the reaction would be if he brought in the National Guard .

And it appears there's still the threat of bringing in Marines. In the last hour the president has posted on social media: "Looking really bad in LA. BRING IN THE TROOPS!!!"

The City of Glendale in California has announced that it will terminate its contract with the Department of Homeland Security (DHS) and Immigration and Customs Enforcement (ICE).

According to the release, the city has tly operated a facility that houses federal immigration detainees with the DHS and ICE since 2007.

"The City recognizes that public perception of the ICE contract—no matter how limited or carefully managed, no matter the good - has become divisive," it says in a news release issued around 19:00 local time on Sunday (03:00 BST Monday).

It adds that the decision "is not politically driven. It is rooted in what this City stands for—public safety, local ability, and trust."

The protests began on Friday after it emerged Immigration Customs Enforcement (ICE) officers were carrying out raids across the city.

The BBC's US partner, CBS, reports that operations took place in the Westlake district as well as in Paramount, south of LA - where the population is more than 82% Hispanic.

There were also reports of an ICE raid at a Home Depot store in Paramount, which officials told the BBC were false.

Immigration raids have ramped up under President Donald Trump's istration, which last month asked federal agents to arrest 3,000 people a day.

ICE later told CBS that 44 unauthorised immigrants were arrested in a single operation at a job site on Friday. Another 77 were also taken in in the greater LA area on the same day.

Following the raids, the Federal Building in downtown LA became the focus of protests after it emerged that detainees were allegedly being held there.

Graffiti was sprayed on the building and objects were thrown at police, CBS reports, leading to an unlawful assembly declaration.

Protests continued into Saturday, prompting Trump to deploy 2,000 National Guard to the Los Angeles area - a move condemned by California's Governor Gavin Newsom and LA Mayor Karen Bass.

After a third day of protests in Los Angeles, we're receiving photos through to our newsroom showing protesters and law enforcement clashing around the city.

Jose Barrera, the national vice president of the League of United Latin American citizens (LULAC), tells the BBC's Today programme that the White House wants "to create civic unrest" in Los Angeles.

Barrera says there is "no need" for Donald Trump to deploy the National Guard when there are 17,000 police personnel in Los Angeles.

He says deploying the troops "increases tensions" and confrontation, which sets a "dangerous precedent".

Speaking about the situation in LA, Barrera says: "There's a lot of unrest but also there's a lot of unity, where we're seeing the of the community standing up, going out, peacefully protesting and looking to defend the immigrants here in the United States."

Barrera says there are "outliers" involved in violent unrest - but the majority of people are protesting peacefully, he says. He adds that much of the city is continuing as "business as usual".

An Australian news correspondent reporting from the LA protests was struck by what appears to be a rubber bullet fired by law enforcement.

Lauren Tomasi, with Australia's Channel Nine, was broadcasting live when she was struck in the leg by the non-lethal round.

A law enforcement officer can be seen turning towards news cameras and firing the round before Tomasi was struck.

Watch the full moment in the video above.

As we've reported, downtown Los Angeles has been declared an "unlawful assembly" area, with protesters told to leave.

Now police say a phone alert has been sent to people in the Civic Center area.

A post by the LAPD Central Division on X says: "Those with cell phones in the area of the Civic Centre have received the alert."

California Governor Gavin Newsom has responded to an alleged arrest threat by a member of Trump's cabinet.

"Trump’s border czar is threatening to arrest me for speaking out. Come and get me, tough guy. I don't give a damn. It won’t stop me from standing up for California," he writes on X.

On Saturday, Trump's "border czar", Tom Homan, said that immigration raids would continue regardless of the protests - and hinted that people could be arrested if they interfered with officers.

Speaking to NBC News, Homan said he would apply the same rule to anyone, including elected officials - but stopped short of accusing politicians of actually impeding officers.

"You cross that line, it’s a felony to knowingly harbour and conceal an illegal alien. It’s a felony to impede law enforcement doing their job," he told NBC.

The Los Angeles Police Department says that business owners are reporting looting.

On X, the LAPD Central Division writes: "Business owners are reporting stores are being looted in the area of 6th St and Broadway. Officers are en route to the location to investigate."

Christal Hayes
Reporting from Los Angeles

I was driving through downtown Los Angeles trying to make my way home when I saw a huge crowd of protesters gathered and what appeared to be a car fire.

I was waiting at a red light watching the group as a van flew through a parking lot and slammed into the intersection where protesters were gathered.

The van appeared to hit several protesters and a bike or scooter belonging to a demonstrator.

The driver - who was shirtless - continued driving erratically in the intersection as people ran. He did multiple circles while driving backwards as protesters and those driving tried to flee.

I couldn’t tell if anyone was injured. I saw several people crying and running.

We saw that same driver earlier tonight speeding through areas that police had blockaded. He nearly slammed into two different police lines before officers ordered him to turn around. He shouted at police and then fled.

Local media report the driver was arrested after a short police chase.

It is much quieter out on the streets now in Los Angeles, but still very tense.

There've been pockets of flare-ups in the last few hours and more intentional vandalism than peaceful protest, at least towards the end of the day.

Sunday started quite quietly - relatively small groups of people protesting about those immigration raids - but things deteriorated with the crowds much bigger, reaching thousands of people in the afternoon.

There was violence, there were attacks on police and police vehicles on the 101 freeway, which has been closed on and off.

Some pretty devastating damage has been done to police vehicles as people tried to set them alight. Police eventually moved in to disperse those crowds.

As we get into night-time hours here, it's still quite tense. There's a lot of uncertainty about how things are going to develop overnight.

On his Truth Social platform, the US president is calling for an end to the protests and urging for a crackdown on demonstrators.

In one post, Trump writes that the LA police chief, Jim McDonnell, has said he will "reassess the situation" about bringing in troops to LA.

"He should, RIGHT NOW!!! Don’t let these thugs get away with this. MAKE AMERICA GREAT AGAIN!!!" Trump writes.

In another post, the president writes: "Looking really bad in L.A. BRING IN THE TROOPS!!!"

A third post that was published a short time later reads: "ARREST THE PEOPLE IN FACE MASKS, NOW!"

A British photographer covering the LA protests was struck by a non-lethal bullet as law enforcement tried to disperse crowds.

Nick Stern, who has lived in the US since 2007, tells the PA news agency that the 14mm "sponge bullet" hit his thigh.
