UPDATE (AP): Dallas police say fourth officer has died after downtown shooting by snipers.
The Dallas police chief says at least two snipers shot 11 police officers during protests, and three of the officers are dead.
Police Chief David O. Brown said police have a suspect cornered in a garage and are negotiating with that person. He says the snipers fired upon officers “ambush style.”
Brown says three of the officers who were injured are in critical condition Thursday night. He says the snipers shot from “elevated positions” during a protest over two recent fatal police shootings.
The gunfire broke out around 8:45 p.m. Thursday. Live TV video showed protesters marching along a street in downtown when the shots erupted and the crowd scattered, seeking cover.
