US President Donald Trump has threatened to “take back” a police-free district where protesters have been given free rein in Seattle.
Police abandoned a precinct in the city on Monday after days of violent confrontation with demonstrators.
Mr Trump said the area had been overtaken by “Domestic Terrorists”, but Washington state leaders told him not to meddle in their affairs.
Since police withdrew, demonstrations in the area have been largely peaceful.
It has been called Chaz, an abbreviation of Capitol Hill Autonomous Zone. Hundreds of people have been gathering there to demonstrate, hear speeches and attend events.
The protests were in response to last month’s death in police custody of an unarmed black man, George Floyd, in Minneapolis, Minnesota.
What did Trump say?
In a series of tweets, the Republican president lashed out at liberal Democratic leaders in the north-western US state of Washington and its most populous city of Seattle.
“Take back your city NOW,” Mr Trump wrote on Thursday. “If you don’t do it, I will.
In another tweet, he said “Domestic Terrorists have taken over Seattle”, saying Washington Governor Jay Inslee was “looking ‘the fool'”.
Mr Inlsee tweeted back on morning: “A man who is totally incapable of governing should stay out of Washington state’s business.”
Seattle Mayor Jenny Durkan told President Trump: “Make us all safe. Go back to your bunker.”
How did the Chaz come about?
The area around East Precinct became a battleground between protesters and police in the past two weeks, leading the governor to send in 200 National Guard troops and the mayor to impose a curfew.
During the violence, demonstrators threw petrol bombs and other missiles at police, cars were torched and looting broke out, according to local media.
At the weekend, Seattle police used tear gas and flash bangs to disperse protesters. Members of the city council rebuked the police department, accusing them of heavy-handed tactics.
Then on Monday, the mayor ordered barricades removed near the precinct and the police building was boarded up.
Since then protesters have taken over a zone spanning about six blocks of Capitol Hill, a hub of the city’s trendy arts scene that has been gentrified in recent years as tech workers drive up property prices.
Local media describe a festival-like atmosphere, with poetry readings, music and movie nights. Free fizzy water, snacks, sunscreen and hand sanitiser are available.
While the protesters say they are leaderless, armed volunteers have been spotted at checkpoints asking for the ID of people entering.
What do the police say?
Police say they want to reopen the precinct and it is unclear how long the autonomous zone will remain.
At a news conference on Wednesday, Assistant Chief Deanna Nollette said the police department had been abandoned because of threats that it would be vandalised or burned. She said the protesters’ barricades were intimidating some residents.
Police Chief Carmen Best posted a video message to officers in which she said the police withdrawal “seems like an insult to you and our community”.
On Thursday afternoon the police chief said claims by Asst Chief Nollette that citizens and businesses were being extorted in the zone were not true and had been based on anecdotal evidence from news and social media.
Ms Best said call response times in the area served by East Precinct are normally between 5-18 minutes, but are now taking almost an hour, reports local Komo News.
She said this means police are not able to respond to reports of assaults, rapes and robberies.
