Fires continued to burn and one person was dead in Minneapolis Thursday after a second night of angry protests over the police killing of an African American man while in custody.
Demonstrators clashed with police, looted stores and set fires to shops and a construction site overnight in the northern US city, and were met with tear gas and rubber bullets fired by police seeking to limit the damage.
Media reports said the city was requesting National Guard troops as well as police from neighboring St. Paul to help keep the peace as more protests were planned Friday over the death of 46-year-old restaurant worker George Floyd, seen as the latest in a long series of unjustified police killings of African Americans.
A bystander video taken Monday showed a handcuffed Floyd gasping for breath as a policeman pressed his knee on his neck after detaining him for allegedly using a counterfeit $20 bill in a purchase.
After at least five minutes under the policeman's knee, Floyd goes still. He was taken to hospital where he was declared dead.
