One dead in Alabama mall shooting

One teen is dead and two others have been injured following a shooting at an Alabama mall prior to Black Friday shopping.

Authorities say the shooting happened about 9.30pm on Thursday at the Riverchase Galleria in Hoover, a nearby suburb of Birmingham.

Police say a fight between two teens, including an 18-year-old, resulted in a gunfire exchange. One teen fled but was confronted by two Hoover police officers.

Captain Gregg Rector said at a news conference that a Hoover officer "did engage that individual, shot him and he is dead on the scene."

The second teen was hospitalised in serious condition. Rector said a 12-year-old girl also struck by gunfire was also hospitalised. Her condition was not immediately known.
