At least four people have been killed and dozens injured in a mass shooting in Birmingham, Alabama, police said.

Birmingham Police Officer Truman Fitzgerald said "multiple gunmen opened fire on a group of people" in the city's Five Points South area late Saturday night local time.

Police recovered the bodies of two men and a woman at the scene and the fourth victim died of gunshot wounds at the hospital, he said.
