Updates To Dallas Shooting At Protest

Update 1: Dallas Police Department has confirmed that five officers were killed among the 10 total officers shot.

Update 2: Twelve police officers shot; two civilians shot; fourth suspect has died after standoff with police, says Dallas Mayor Mike Rawlings.

Earlier: Tonight, reports of shots fired at a protest in downtown Dallas emerged as someone opened fire at a Black Lives Matter protest. Dallas Area Rapid Transit (DART) has confirmed that four DART officers were shot and one has died. Earlier update: Dallas Police Department chief confirmed that two snipers shot 10 police officers from an elevated distance and three officers have died, Associated Press reported.

Of the seven officers who are still alive, two are currently in surgery and three are in critical condition.

One reporter on the scene said the climate in downtown Dallas is "like a war zone".

After an hours-long standoff with police, one of the sniper suspects reportedly shot himself around 2:30 a.m. CT.

During a press conference at 12:30 a.m. CT, Dallas Police Department (DPD) Chief Brown said police were negotiating with one suspect who had holed himself up in the parking garage of the El Centro College, and that negotiations weren't going as well as they'd planned. The suspect reportedly told police that "the end is near" and that he'd planted bombs "all over the place". The police chief also said they're unsure if all suspects were known or in custody.

At 12:30 a.m. ET, DPD reported that they have one suspect in custody. Another "person of interest" had turned himself in, although video of this person showed him surrendering his gun to police when the shooting first occurred.

A police car chase ended in the apprehension of two additional suspects who were reportedly seen throwing a suspicious package into the back of a Mercedes near the scene of one of the shootouts. These individuals were arrested and taken into custody. DPD police chief said at a press conference that all four people were likely involved in the protest shooting.

DPD reportedly found a suspicious package near one of the shootout locations. In a press conference, the DPD police chief said one of the suspects reportedly threatened to plant a bomb.

Around 11 p.m. ET, two other people were arrested, although they do not appear to be the snipers who shot the officers.

During their latest press conference, the mayor of Dallas said that most of downtown is considered a crime scene and accordingly blocked off. He cautioned people who work downtown not to go to work in the morning, as it will be nearly impossible to get around downtown Dallas due to roadblocks.

A majority of streets in downtown Dallas are blocked off by police, and some officers told a CBS reporter and his cameraman to turn their camera lights off so they won't get shot.

Earlier in the night, police warned of a possible active shooter situation at the nearby Omni hotel, but that situation has since cleared and the reported gunman had left the building.

Two of the people shot, including the one civilian, have been identified. The civilian's name is Shetamia Taylor, and one of the DART officer's names is Misty McBride. Both are recovering in the hospital.
