Two protesters were killed and one injured during the third night of unrest in the United States city of Kenosha.
Local media reports said the violence was believed to have stemmed from a conflict between protesters and armed men guarding a petrol station.
Protests broke out after the police shot a black man, Jacob Blake.
Video showed the 29-year-old being shot at several times as he leaned into a car. The shooting injured him and his lawyers said it would take “a miracle” for him to walk again.
People have since defied emergency curfews in the city to join protests, which at times have turned violent.
Kenosha Police said officials responded to “reports of shots being fired and multiple gunshot victims” in the city at about 23:45 on Tuesday.
“The shooting resulted in two fatalities and a third gunshot victim was transported to a hospital with serious, but non-life threatening injuries,” the statement said.
It added that the identities of the victims were still being determined and that no further details would be given at this time. An investigation has been opened.
Kenosha County Sheriff David Beth earlier told the New York Times that an investigation into the shootings would be focused on a group of men armed with guns outside a petrol station.
Wisconsin Governor Tony Evers said on Tuesday he was sending more National Guard troops to the city amid the unrest.
