Northern Irish expats caught up in the US street disturbances have told of the fear and horror gripping their adopted communities.
At least 40 American cities have imposed strict curfew measures after days of civil unrest sparked by the killing of George Floyd.
His death has led to deep anger over police brutality and racial injustice in America, bringing thousands of people onto the streets in protest.
Omagh-born producer Phelim McAleer (53) lives in Venice, California, with his wife Ann. The couple produce the podcast The Ann and Phelim Scoop.
He said there was a "criminal element" to the trouble.
"On Sunday I was over in Santa Monica, our neighbouring beach community, covering the rally that was going on there for the podcast," he said. "They were blocking the roads and other people were looting.
"Santa Monica is a very affluent and prosperous community. I saw looters go into dozens of shops. It was shocking to see. They were like locusts, swarming in and completely cleaning it out in minutes. It was an amazing sight to see. Windows were smashed and everything gone from the shops.
"That's one of the main differences with Northern Ireland riots, the widespread looting.
"It's also very unpredictable because a criminal element is going to the protests - and they don't care - so there is an unpredictability where violence can just erupt without warning."
Mr McAleer said there is fear in the community, saying people are worried.
He added: "I would compare it to the worst days of the Troubles where people went about their business most of the time, but in times of stress people were afraid to go out or into the city centre.
"That's what it's like here. People are not going out. And there's a curfew on also. We have to be indoors by 6pm."
Mr McAleer said that the disturbances have hit the community hard.
West Belfast video producer Stevie Kane (43) lives in south Minneapolis with his wife Harmony and their one-year-old daughter.
He lives close to one of the flashpoints, adding that he is on the "very edge of the 'heat map'".
Mr Kane added: "We live in an affluent area so the idea that it might come near my house is highly unlikely. But right around the corner from us one of the petrol stations was on fire the other day, so there has definitely been property damage near us.
"We are about a five minute drive away from the main hot spots. So we are in the area, but I don't have much concern for my home, but my wife does. It's probably because I grew up with this kind of thing - not all the time, but some of the time.
"The atmosphere here in Minneapolis is really grim at the moment. I had to go across town to collect some things from a friend's house yesterday. He lives closer to the hot spots. As I was driving I could see that everything was boarded up. People are writing 'BLM - Black Lives Matter' on the boards or that property is 'black owned' there too."
Mr Kane believes that Mr Floyd's killing has resulted in a 'sea change' in America.
He added: "The big thing with regards the George Floyd situation that concerns me is that this is how high the bar has to be for people to pay attention.
"I'm seeing a lot of conservatives in positions of authority saying that it is terrible what happened to George. I agree, but they didn't say the same thing when Philando Castile was shot dead by a police officer in 2016. They weren't saying the same thing because he had a weapon.
"This is how high the bar has to be to get right wing conservatives on board with the idea that policing is maybe not perfect. You have to crush a guy's windpipe with your knee for nine minutes on camera."
