Nine people were wounded on Thursday evening (US time) in Rhode Island's capital in what police there believe to be the largest shooting in city history.
Of the nine, three had serious injuries and were "maybe critical," Providence Police Chief Colonel Hugh T Clements told reporters at the scene.
He said multiple guns were used and it involved an "ongoing feud" involving two groups known to authorities.
He said the shooting began with gunfire emanating from a vehicle, targeting a home. A person or people inside the home then returned fire. He described the participants as "young men."
The shooting took place just before 7pm in the southeastern neighbourhood of Washington Park, which Clements described as a typically quiet neighbourhood.
