Tragedy has struck again in Baton Rouge, Louisiana, as three police officers were killed and three more injured in a shooting.
Police have been able to gun down one suspect, but warn there may be two others in hiding.
They are also warning people to stay away from the scene of the shooting, which is close to the police headquarters and a highway.
The local sheriff’s department spokesperson said that the incident happened shortly before 9am, local time, and was being treated as an active situation, with road closures in the area.
It was not immediately clear whether there was a link between the shootings and the recent unrest over the police killings of black men in Baton Rouge and Minnesota.
Authorities did not give any information about the gunman’s possible motive.
President Barack Obama condemned the “attack on law enforcement in Baton Rouge” and vowed that justice would be done.
“We may not yet know the motives for this attack, but I want to be clear: There is no justification for violence against law enforcement. None. These attacks are the work of cowards who speak for no one,” Obama said in a statement.
The Louisiana State Governor, John Bel Edwards, has condemned the attack, but has promised the perpetrators would be brought to justice.
