At least three Baton Rouge police officers were killed and three others injured Sunday morning, the city's mayor and the East Baton Rouge Parish Sheriff's Office said.
At least one suspect is dead, but law enforcement officials believe two others may be at large, the sheriff's office said. A senior law enforcement official said the suspect wore black fatigues and was armed with a rifle.
The attack comes less than two weeks after the fatal shooting of a black man by police sparked protests in Baton Rouge, turning the city into the latest flashpoint in the ongoing debate over law enforcement tactics.
The officers were responding to a call of shots fired when they were gunned down in an apparent "ambush" around 9 a.m. local time, Baton Rouge Mayor Kip Holden told MSNBC.
