Three police officers were shot to death and several others wounded in Baton Rouge, Louisiana on Sunday, the city's mayor said, as the country remained on edge in the wake of police shootings of black men and the killings of five Dallas officers.
The officers in Baton Rouge were responding to a call of shots fired when they were ambushed by at least one gunman, Mayor Kip Holden told NBC News.
One suspect is dead and police are checking the shooting scene with a robot to make sure there are no explosives, Baton Rouge Police spokesman L'Jean Mckneely said.
Police told reporters authorities are seeking more than one suspect and said the public should be on the lookout for people dressed in black and carrying long guns.
Earlier, a spokesman for the East Baton Rouge Sheriff's Office said police and sheriff's deputies were involved in the shooting incident, which occurred around 9 a.m. local time.
