Protests have broken out across the US after a public observer was fatally shot at an ICE raid in Minneapolis, Minnesota.
It's the latest flashpoint in US President Donald Trump's widespread crackdown on immigration, which last year saw thousands of military troops patrolling city streets.
Here's what to know.
What happened in Minneapolis?
An immigration agent shot and killed a 37-year-old woman in her car during a raid in the south of Minneapolis, Minnesota, on Wednesday, local time.
Renee Nicole Good had been at the scene as a legal observer — a volunteer who monitors government officers at protests and operations, documenting interactions and deterring misconduct.
US President Donald Trump claimed the agent fired in self-defence, accusing Ms Good of being a "professional agitator".
"The woman driving was very disorderly, obstructing and resisting, who then violently, wilfully and viciously ran over an ICE officer," he wrote on social media.
But witness statements and footage of the incident, verified by the ABC, raise doubts about that account.
Videos taken from different vantage points show an officer approaching a maroon Honda SUV stopped in the middle of the road, demanding the driver open the door and grabbing at the handle.
The Honda Pilot begins to pull forward as its wheels turn to the right in an apparent effort to head up the street and away from the scene.
An officer standing in front of the vehicle pulls his weapon and immediately fires at least two shots into the SUV at close range.
Minneapolis Mayor Jacob Frey slammed the president's description of the incident, calling it a "garbage narrative".
"Having seen the video myself, I want to tell everybody directly — that is bullshit," he said at a press conference.
Minnesota Governor Tim Walz said the Trump administration's narrative of the event was "propaganda".
The shooting quickly drew crowds of angry protesters and by evening, hundreds had gathered for a vigil to mourn Ms Good's death and urge public resistance of immigration enforcers.
What is ICE?
ICE, which stands for Immigration and Customs Enforcement, is a law enforcement agency under the Department of Homeland Security.
It's responsible for enforcing the US's immigration laws and is tasked with arresting people it believes are in the country illegally.
What are ICE agents doing in Minneapolis?
Their presence in the city is part of an effort by the president to massively increase the number of deportations carried out by the agency.
When he was campaigning ahead of his election, Mr Trump promised to carry out the "largest deportation operation in American history" if he was returned to office.
He has accused undocumented immigrants of fuelling a spike in violent crimes and "poisoning the blood of our country".
Under his direction, ICE has ramped up the number of arrests it makes and has carried out raids to capture people the agency claims are undocumented immigrants.
Crackdowns have targeted metropolitan areas with large immigrant populations, including Los Angeles, New York and Chicago.
In several cases, states' National Guard troops have been federalised by Mr Trump, despite objections from the states themselves, and deployed to guard immigration enforcement action from protests and public interference.
The president has sent as many as 2,000 federal agents and officers to the Minneapolis area this week to carry out the "largest immigration operation ever".

Prosecutors say billions of dollars were stolen from federally funded health care benefits and a COVID-19 program in recent years.
The state has the largest Somali population in the US — a group Mr Trump called "garbage" in December and said he didn't want in the country.
Mr Trump has also criticised Mr Walz, a Democrat, for failing to catch the alleged crimes.
Is Minnesota a blue state?
Mr Trump's opponents say his motivations are politically charged.
They have accused him of targeting cities and states with diverse populations and Democratic leaders, rather than those with high crime rates.
Many cities topping the violent crime rates statistics have not been named as potential targets, and among US cities with the highest violent crime rates, Minneapolis ranked 14 in FBI data from 2024.
Ahead of it were several red cities in red states that have not been subject to, nor earmarked for, widespread immigration enforcement crackdowns, such as Cleveland, Ohio and Kansas City, Missouri.

A Republican presidential candidate has not won the state since 1972, when Richard Nixon beat George McGovern with a 5.51 per cent margin.
The state's last Republican governor was Tim Pawlenty, who served from 2003 to 2011.
Are illegal immigrants responsible for a crime crisis in the US?
Since the presidential election in 2024, Mr Trump and Republicans have pointed to a handful of high-profile violent crimes allegedly committed by people who were in the US illegally.
But there is no data to suggest the demographic is fuelling a crime wave.
Studies have found undocumented migrants are less likely to be arrested for violent, drug and property crimes than US-born citizens.
Texas is the only state that tracks crimes by immigration status, and a peer-reviewed study that used that data in 2020 found "considerably lower felony rates" among people in the US illegally when compared with legal immigrants or US-born citizens.
A 2018 analysis of more than 50 studies published in the Annual Review of Criminology found higher immigration rates were generally associated with reduced violent crime rates or had no significant effect.
Meanwhile, a 2022 study published in the American Journal of Public Health found US-born adults were 2.5 times more likely to report engaging in violence toward others than first-generation immigrants, regardless of their documentation status.
While crime rates have reduced since Mr Trump took office, it's part of a trend that began under former president Joe Biden.
All available figures show violent crime declined in 2023 after a spike during the pandemic.
Where are National Guard troops currently stationed?
National Guard troops are currently deployed in Memphis, New Orleans and Washington DC.
[LINK: National Guard deployment map]The Trump administration attempted to send troops to Portland and Chicago last year, but that move was blocked by courts following legal challenges.
While thousands of National Guard troops were deployed to Los Angeles in early June, a court ordered their deployment to end, and they were withdrawn in December.
Several other cities have also been earmarked for future deployments, but plans are not yet in motion.
