DALLAS — Disturbing footage captured the shooting of one of eleven officers shot during an attack in Dallas Thursday.

The footage, first broadcast by FOX News, shows a gunman rushing an officer during a gunfire exchange and shooting the officer point blank. It is unclear whether the officer is among the four dead.

Four officers have died and seven are wounded after attackers opened fire during a protest against police violence in downtown Dallas.

At least one suspect and a person of interest have been taken into custody.
