Watch: Clashes continue in LA over immigration raids
The National Guard and people protesting against immigration raids clashed in Los Angeles
US President Donald Trump says he has deployed 2,000 National Guard troops to Los Angeles to uphold "very strong law and order", after violent protests against immigration raids erupted in America's second-biggest city.
Dozens of people have been arrested in Los Angeles after days of violent protests, which erupted following immigration raids.
His decision to summon the National Guard overruled the authority of California Governor Gavin Newsom, who called the move "purposefully inflammatory".
US President Donald Trump deployed 2,000 National Guard troops to the city, triggering a political row. He also condemned what he called "violent, insurrectionist mobs".
At least 118 immigrants have been arrested in operations across the city over the past week, which led to clashes as demonstrators gathered outside businesses that were thought to have been raided.
Vehicles have been set on fire and there have been reports of looting in affected areas of America's second largest city.
The LA County Sheriff's Department said crowds "became increasingly agitated, throwing objects and exhibiting violent behaviour", prompting police to use tear gas and stun grenades.

Governor Newsom, along with the LA mayor and a California congresswoman, said in separate comments they believed local police could handle the protests. Twenty-nine people were arrested, according to local officials.

Can the president deploy the National Guard?
Why are people protesting in LA?
To quell the growing unrest, Trump issued a directive under a rarely used federal law that allows the president to federalise National Guard troops under certain circumstances.
The protests began on Friday after it emerged Immigration Customs Enforcement (ICE) officers were carrying out raids in areas of the city with prominent Latino populations.
The National Guard acts as a hybrid entity that serves both state and federal interests. Typically, a state's National Guard force is activated at the request of the governor.
Raids have stepped up after Trump returned to the White House and pledged to crack down on illegal immigration.
In this case, Trump has circumvented that step by invoking a specific provision of the US Code of Armed Services titled 10 U.S.C. 12406, which lists three circumstances under which the president can federalise the National Guard.
The BBC's US partner, CBS News, reported that recent operations took place in the Westlake district as well as in Paramount, south of LA - where the population is more than 82% Hispanic.
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".
There were also reports of an ICE raid at a Home Depot shop in Paramount, which officials told the BBC were false.
Trump said in his memorandum requesting the National Guard that the protests in Los Angeles "constitute a form of rebellion against the authority of the Government of the United States".
ICE later told CBS that 44 unauthorised immigrants were arrested in a single operation at a job site on Friday. Another 77 were also arrested in the greater LA area on the same day.
The National Guard's role in Los Angeles will be to protect federal agents, including US Immigration and Customs Enforcement (Ice) and Homeland Security, as they carry out their duties.
Where are the protests, and what's happened?
The troops will not be conducting their own immigration raids or performing ordinary law enforcement activities against civilians.
The protests have been largely limited to downtown LA, which has been declared an "unlawful assembly" area by police after days of clashes.
Vehicles were set alight on Sunday, and police accused protesters of using incendiary devices against horse patrols. Meanwhile, officers in riot gear have used flash-bang grenades and pepper spray to subdue crowds. The unrest temporarily brought the 101 freeway to a halt, and there were reports of looting
The downtown Federal Building has become a flashpoint after it emerged that ICE detainees were allegedly being held there. On Saturday, ICE accused "over 1,000 rioters" of surrounding and attacking the building
A Home Depot shop in Paramount, roughly 20 miles (32 km) south of downtown LA, has become another key protest site. Tear gas and flash-bangs were deployed against protesters who also gathered on Saturday, and armed National Guard troops guarded a nearby business park on Sunday
The Los Angeles Police Department (LAPD) said it made 29 arrests on Saturday. A further 27 people were arrested on Sunday
Separately, about 60 people were arrested and three officers injured following unrest in San Francisco on Sunday, police there said
Elsewhere in the sprawling city of LA, life continues as normal - and some areas were closed off over the weekend for the LA Pride parade.
What is the National Guard, and why did Trump deploy it?
Watch: 'We'll be very, very strong in terms of law and order' - Trump
On Saturday, Trump deployed 2,000 National Guard members to the Los Angeles area, triggering a political row with state politicians.
The National Guard acts as a hybrid entity that serves both state and federal interests. Typically, a state's force is activated at the request of the governor.
Trump circumvented that step by invoking a rarely-used federal law, arguing that the protests constituted "a form of rebellion against the authority of the government of the United States".
This is reportedly the first time the National Guard has been activated without request of the state's governor since 1965.
The move has been condemned by California Governor Gavin Newsom and LA Mayor Karen Bass, who said they believed local police could handle the situation.
Newsom accused Trump of an "illegal" act that was "putting fuel on this fire", and has threatened to sue.

What are the other agencies involved?
The role of the National Guard is to protect federal agents, including ICE and Department of Homeland Security (DHS) personnel, as they carry out their duties.
The troops will not be conducting their own immigration raids or performing regular policing - which remains the role of the (LAPD).
The law generally prohibits domestic use of federal troops for civilian law enforcement, outside of some exceptions like the Insurrection Act.

Although Trump has threatened to invoke that act in the past, during the Black Lives Matter protests of 2020, for example, he has not done so here.

According to experts, this is the first time the National Guard has been activated without request of the state's governor since 1965.
Trump's allies have defended his decision to mobilise the National Guard. Defence Secretary Pete Hegseth also said active-duty US marines stationed at nearby Camp Pendleton would be sent if needed and were on "high alert".
In 1992, the National Guard was federalised in LA during riots after police officers were acquitted for the beating of black motorist Rodney King.
Then-President George HW Bush sent troops at the request of California's governor at the time, Pete Wilson.
In 2020, National Guard troops were deployed in some states in the wake of protests over the killing of George Floyd.
How have officials responded to Trump's order?
Senior figures in the Trump administration have backed the president's decision to mobilise the National Guard. Defence Secretary Pete Hegseth said on social media it was "COMMON SENSE", adding: "Violence & destruction against federal agents & federal facilities will NOT be tolerated."
Hegseth also said that active duty US Marines stationed at nearby Camp Pendleton would be sent if needed and were on "high alert".
Senator Markwayne Mullin, an Oklahoma Republican, told CNN: "Does it look like it's [the protests] under control? Absolutely not."
However, several Californian officials insist city police are equipped to deal with the unrest, and the military's involvement is unnecessary.
California congresswoman Nanette Barragán, a Democrat who represents the city of Paramount in LA's suburbs where the protests have taken place, told CNN: "We don't need the help."
The National Guard is "only going to make things worse", she said.
Her words echo Governor Newsom, who also spoke against National Guard troops being sent to his state.
"The federal government is taking over the California National Guard and deploying 2,000 soldiers in Los Angeles - not because there is a shortage of law enforcement, but because they want a spectacle," Newsom wrote on X.
LA Mayor Karen Bass told ABC7 the National Guard was not needed.
What has ICE been doing in LA?
What has ICE been doing in LA?
Ice officers conducted raids in heavily Latino parts of LA on Friday, as part of Trump's crackdown on illegal immigration.
The recent raids are part of the president's aim to enact the "biggest deportation operation" in US history. Los Angeles, where over one-third of the population is born outside of the US, has been a key target for operations.
Forty-four people were arrested, said a spokesperson for Homeland Security Investigations, a branch of ICE.
In early May, ICE announced it had arrested 239 undocumented migrants during a week-long operation in the LA area, as overall arrests and deportations lagged behind Trump's expectations.

The following month, the White House increased its goal for ICE officials to make at least 3,000 arrests per day.

Authorities have expanded their search increasingly to include workplaces such as restaurants and retail shops.

The ambitious deportation campaign has included removing migrants to a mega-prison in El Salvador, including at least one who was in the US legally. Many of Trump's actions have been met by legal challenges.
The following month, the White House increased its goal for Ice officials to make at least 3,000 arrests per day.
Authorities have expanded their search increasingly to include workplaces such as restaurants and retail shops. The LA raids that sparked the protests occurred at a wholesale clothing supplier and a Home Depot outlet.
"You're going to see more work site enforcement than you've ever seen in the history of this nation," Trump's border official Thomas Homan said.
The ambitious deportation campaign has included rounding up migrants on military planes and sending them to Guantanamo Bay before bringing them back to Louisiana.
Other migrants have been deported to a mega-prison in El Salvador, including at least one who was in the US legally. Some migrants have been sent to countries where they are not from.
Many of these actions have been met by legal challenges in court.
How has LA responded to the raids?
On Friday, protesters clashed with federal agents outside a clothing wholesaler. They threw objects at agents and attempted to block federal officials from carrying out their arrests. In response, officials in riot gear used flash bang grenades and pepper spray to subdue the crowd.
Outside a Home Depot store in Paramount, roughly 20 miles (32 km) south of downtown LA, tear gas and flash bangs were deployed against protesters that gathered again on Saturday.
In a social media post, Ice described the scene on Saturday, saying: "Our brave officers were vastly outnumbered - over 1,000 rioters surrounded and attacked a federal building."
Responding to the protests, the LA Police Department said it made 29 arrests, almost all for failure to disperse, which is a misdemeanour, according to the BBC's media partner CBS News.
On Sunday, day three of the protests, National Guard troops arrived to LA and were seen walling off protesters outside of a federal building that contains a detention centre.
In one of the more tense exchanges, federal officers with Department of Homeland Security badges fired what appeared to be tear gas and pepper spray and some kind of non-lethal round towards the crowd.
