Multiple people have been injured and four have been killed in a shooting in Alabama, officials have said.

The incident is reported to have taken place at a teenager’s birthday party late on Saturday evening in the city of Dadeville, in Tallapoosa County.

It was not immediately known if a suspect was in custody.

WRBL-TV reported it occurred at a dance studio. The station showed images of crime scene tape around the Mahogany Masterpiece Dance Studio and neighbouring buildings, as well as a heavy police presence.

The Alabama Law Enforcement Agency said the shooting happened at about 10.30pm and gave no information about a possible motive.

Alabama Governor Kay Ivey said in a statement: “This morning, I grieve with the people of Dadeville and my fellow Alabamians.

“Violent crime has no place in our state, and we are staying closely updated by law enforcement as details emerge.”

Dadeville is a small city of about 3,000 people 45 miles northeast of Montgomery, Alabama.

There have been 162 mass shootings so far this year, according to Gun Violence Archive.
