Two people have been shot in Ferguson after a confrontation between protesters and police at an event marking the first anniversary of the death of a black teenager Michael Brown.
Footage has emerged from the city in which a series of shots can be heard being fired near a convenience store with people screaming and running for cover.
St Louis County police say they came under fire with two unmarked police cars being hit by gunshots.
After a day of peaceful rallies to mark the shooting of the teenager by a white policeman which lead to a series of riots last summer, the scene changed dramatically with dozens of protesters blocking traffic and smashing store windows.
