UPDATE: A fifth officer has been pronounced dead, six officers are recovering and there are currently four suspects, with one suspect claiming bombs were also planted downtown.

Dallas Police have rounded up two suspects who unloaded their weapons during a Dallas protest tonight [Thursday, July 7], hitting eleven officers and killing four. The protest was in response to the recent shooting deaths of Alton Sterling and Philando Castile at the hands of police.

At least eight other Dallas police officers were hit, including three that are in critical condition; three additional DART officers suffered injuries that were not life threatening in the shooting.

Dallas Police Chief David Brown released the following statement:

“Tonight it appears that two snipers shot ten police officers from elevated positions during the protest/rally. Three officers are deceased, two are in surgery and three are in critical condition. Please keep us in your thoughts and prayers tonight.”

The ATF [Bureau of Alcohol, Tobacco, Firearms and Explosives] and FBI have joined the investigation, and Chief Brown said agents are searching downtown for the possibility that there may be a bomb planted somewhere.
