POTUS: This is an American Problem

5 officers killed, several more injured by snipers during protest in downtown Dallas

DALLAS – Shooters killed five officers during protests against police in downtown Dallas, marking the deadliest single attack on U.S. law enforcement since September 11, 2001.

Gunfire rang out Thursday night as demonstrators marched against the shooting deaths of two African-American men by police in Louisiana and Minnesota.

A total of 11 officers were shot, Dallas police said. A standoff is underway as authorities try to negotiate with a suspect in a downtown garage.

It was the deadliest single attack on law enforcement since the 2001 terror attacks, when 72 officers died, according to the National Law Enforcement Officers Memorial Fund.
