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 curfew that lasted until 06:00 (11:00 GMT), telling people to “be safe, go home”.
Tensions in Minneapolis are high as the trial of a former officer accused of killing George Floyd takes place.
A courtroom just 10 miles (16km) from the latest unrest will resume proceedings on Monday, with the prosecution expected to wrap up its case and the defence of the ex-officer, Derek Chauvin, to begin.
What’s the latest at the scene?
Hundreds of protesters chanting Daunte Wright’s name gathered late on Sunday outside the police headquarters in Brooklyn Center.
Tensions rose as police donned riot gear, and two police vehicles were pelted with stones and jumped on, Reuters news agency reported.
Protesters wrote with 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.
About 20 businesses in a nearby shopping centre were later broken into, the StarTribune reported, with sporadic looting spreading to other areas of Minneapolis.
Brooklyn Center Mayor Mike Elliott announced on Twitter he was issuing a curfew until 06:00.
In an early-morning video post on the death of Daunte Wright, Mayor Elliott said “our hearts are with his family” and pledged “we are going to make sure that everything is done in our power to ensure justice”.
He urged people protesting to do so peacefully.
Members 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.
Some remained on the streets after the curfew ended, but by that time the crowds had mainly dispersed.
Brooklyn Center has closed all school buildings, programmes and activities for Monday, local media report.
The mayor has scheduled a press briefing for 11:00 (16:00 GMT).
