Three police officers are dead and three more are wounded in Baton Rouge following another attack on police officers.
One suspect is also dead while two more are thought to be at large.
Police are using a specialized robot to check for explosives near the body of a suspect.
Tensions are high following the death of 37-year-old Alton Sterling, a black man. He was killed by white officers earlier this month.
The public is advised to call 911 immediately if they see anything suspicious.
Earlier this month Micah Xavier Johnson ambushed and fired upon a group of police officers in Dallas, Texas, killing five officers and injuring nine others.
