Multiple gunshots were fired on Tuesday near the site in Minneapolis where people were marking the first anniversary of the murder of George Floyd.
Police and witnesses said that several gunshots were heard and a car was seen leaving the area at a very high speed. At least one person was taken to hospital with gunshot injury, the police said.
An AFP photographer at the intersection in Minneapolis known as George Floyd memorial square said a crowd which had gathered to mark the first anniversary of Floyd's death scattered when the shots were heard.
Former police officer Derek Chauvin was convicted of murder last month over Floyd's death on May 25, 2020. The death had sparked protests against racial injustice and police brutality across the United States.
