Tear gas has been fired and a curfew imposed amid angry protests after police fatally shot a black man in a traffic stop in the US city of Brooklyn Center, just north of Minneapolis.
The man has been identified by relatives as 20-year-old Daunte Wright.
Brooklyn Center’s mayor issued a city-wide curfew until 06:00 (11:00 GMT), telling people to “be safe, go home”.
Minnesota Governor Tim Walz said he was “closely monitoring the situation” and praying for Mr Wright’s family.
Hundreds of protesters chanting Daunte Wright’s name gathered late on Sunday outside the police headquarters in Brooklyn Center, just a few kilometres north of central Minneapolis.
Protesters wrote chalk on pavements and lit candles, but police later ordered the protesters to disperse, with footage showing tear gas and stun grenades being fired by officers.
Local media reported some looting taking place in a number of areas and Brooklyn Center Mayor Mike Elliott announced on Twitter he was issuing a curfew until 06:00.
“We want to make sure everyone is safe. Please be safe and please go home,” he wrote. Some of the Minnesota National Guard, already deployed for the murder trial of Derek Chauvin over the death of George Floyd, were sent to Brooklyn Center.
Brooklyn Center has closed all school buildings, programmes and activities for Monday, local media report.
