(CNN) — Five Dallas police officers were killed in the deadliest incident for law enforcement in the United States since 9/11, according to statistics from the National Law Enforcement Officers Memorial Fund.

A total of 12 officers were shot at a protest that took place Thursday against police brutality.

“To say our police officers put their lives on the line everyday is not a hyperbole, it’s a reality,” said Mayor Mike Rawlings in a press conference early Friday morning.

Dallas Police Chief David Brown said that he was proud of the officers and saw “the courage and professionalism and their grit to stay on scene to search for the suspects while we’re vulnerable.”
