Protesters took to streets across the United States overnight and into the early hours of this morning, sparking clashes with police and a fatal shooting in Texas, amid a wave of public anger over Donald Trump's planned "surge" of federal agents into main cities.
The demonstrations against racism and police brutality come as the US president faces an increasingly tough battle for re-election, and is campaigning on a "law and order" platform.
Federal officers have been confronting protesters in Portland since at least 27 June.
President Trump and US Attorney General William Barr cited Chicago, Detroit, Baltimore, Kansas City, Albuquerque and New York City as possible targets for future deployments of federal officers.
The decision follows widespread unrest ignited two months ago by the death in Minneapolis of African-American George Floyd.
Protesters marched today outside Homeland Security Acting Secretary Chad Wolf's home in Alexandria, Virginia, demanding an end to the deployment of federal officers.
Some held up signs saying "abolish the Department of Homeland Security" and "resist Trump's troops".
Last night, police and federal agents in Portland, Oregon fired tear gas and forcefully dispersed protesters for a second night. Police moved after a group of protesters tried to pull down a fence erected around a federal courthouse.
Portland has taken centre stage for the highly controversial crackdown by federal agents ordered by Mr Trump - one that is not supported by local officials, and which many say smacks of authoritarianism.
An AFP reporter saw at least two men being detained and escorted from the scene by federal officers.
Portland police earlier confirmed a man was stabbed, with the suspect "held down by protesters" before he was detained by officers and charged with assault, according to a statement.
The victim was transported to hospital with a serious injury.
Mr Trump's troops plan has met with stiff resistance from several city mayors, many of them Democrats who accuse the US president of magnifying the problem for political gain.
"I have drawn a very hard line. We will not allow federal troops in our city," Chicago Mayor Lori Lightfoot told CNN.
"We will not tolerate unnamed agents taking people off the street, violating their rights and holding them in custody."
Protesters marched in Austin, Texas, as well as Louisville, Kentucky; Seattle, Washington; New York; Omaha, Nebraska; California's Oakland and Los Angeles, and Richmond in Virginia.
In Austin, a man was killed in a shooting in the downtown area of the Texas state capital, police said.
A witness, Michael Capochiano, told the Austin Statesman newspaper that the incident occurred when a man in a car turned onto a street where protesters were gathered and drove toward the crowd.
The vehicle became surrounded by shouting protesters, and one approached the vehicle carrying a rifle, he said.
The driver then stuck a gun out of the car window and fired several shots, hitting the man with the rifle, before speeding away, according to Mr Capochiano.
Police said the shooter was in custody, and cooperating with investigators.
In Seattle, police arrested 45 people during a night of violent protests in which demonstrators set fire to trailers by a construction site for a youth detention facility.
Protesters slashed car tires and smashed trailer windows, prompting police to declare a riot and clear the streets with pepper spray and flash-bang grenades.
