BATON ROUGE, La. (AP) — Police in Louisiana say that several officers have been shot in Baton Rouge while on duty.

The shooting happened early Sunday, less than 1 mile from police headquarters.

Baton Rouge Police Sgt. Don Coppola did not know the extent of the injuries or give the precise number of officers injured. He says they were rushed to a local hospital.

He said that authorities believe the “scene is contained,” meaning that a shooter was unlikely on the loose.

Police-community relations in Baton Rouge have been especially tense since the killing of 37-year-old Alton Sterling, a black man killed by white officers earlier this month after a scuffle at a convenience store. The killing was captured on cellphone video and circulated widely on the internet.
