Multiple police officers in Baton Rouge, Louisiana, were shot on Sunday (July 17) morning, and three of the officers have died, according to Baton Rouge Mayor Kip Holden.

The officers were taken to a local hospital, Baton Rouge Police spokesman Sergeant Don Coppola told the local CBS affiliate, adding he did not know the extent of their injuries. Sheriff's deputies may have also been involved.

While the scene of the shooting was contained, police have still not taken the shooter into custody and warned local residents to stay away from the scene, near Airline Highway.

The reports come a week after a wave of protests against police violence in Baton Rouge and other cities after a 37-year-old father of five was shot and killed at close quarters by law enforcement officers. At one of the demonstrations in Dallas, a gunman opened fire on white officers assigned to the protest, killing five of them.

Telephone video footage carried on a local news station showed police cars arriving at a suburban intersection, and then five shots rang out.

A WFAB reporter at Our Lady of the Lake Regional Medical Center, where the injured officers were taken, said the flag outside was at half staff.
