WASHINGTON (AP) – President Barack Obama says he condemns, in the strongest sense of the word, the attack on law enforcement in Baton Rouge.

Obama says the attacks on police officers, the second in two weeks, are “attacks on public servants, on the rule of law, and on civilized society, and they have to stop. “

Obama is responding Sunday after three police officers in Baton Rouge were fatally shot and three others wounded. Obama says he has offered the full support of the federal government to Louisiana state and local officials.

Obama says the motives for the attack are unknown, but there is no justification for violence against law enforcement. He said the attacks are the work of cowards who speak for no one.
