Three US police officers dead in Baton Rouge shooting: police
Three police officers were killed and three injured in a shooting in Baton Rouge, Louisiana on Sunday, police said.
"One suspect is dead, law enforcement believes two others may be at large," the East Baton Rouge Sheriff's Office said in a statement.
Local television station WAFB aired video footage of police responding to the scene in Baton Rouge. Multiple shots could be heard as civilian cars quickly backed away.
CNN reported a local source as saying at least seven officers were shot and three are feared dead. Some of the others are reported to be in critical condition, the station said.
The shooting appeared to be carried out by a lone gunman carrying an assault rifle, local media reported.
"We think that the situation has been contained," Coppola said.
Police arrested more than 100 protesters taking part in a demonstration against police brutality in Baton Rouge last week.
