DALLAS — At least five Dallas police officers were killed and seven others wounded Thursday evening in an attack by snipers in downtown city streets that followed a peaceful protest over recent police shootings. The Dallas police chief said an attacker told authorities “he was upset about the recent police shootings” and “wanted to kill white people, especially white officers.”
The city’s downtown suddenly exploded into violence at around 9 p.m. when gunshots echoed through the streets, sending protesters and police officers alike scattering for cover. Authorities said two civilians were also injured during the shooting.
“We’re hurting,” Dallas Police Chief David Brown said Friday morning. “Our profession is hurting. Dallas officers are hurting. We are heart broken.”

Four Dallas police officers and one Dallas Area Rapid Transit officer were killed by “snipers” perched atop “elevated positions,” officials said.
Only one of the killed police officers had been identified as of early Friday morning:DART officer Brent Thompson, 43.
Police have not officially released the identity of any suspects, but a senior U.S. law enforcement official familiar with the probe identified an attacker who died after a standoff with police as Micah Xavier Johnson, 25, who is believed to be from the Dallas area.
Videos circulating on social media showed a person with an assault-style rifle shoot a police officer in the back at point-blank range.

A gunman, believed to be the same shooter, then engaged in a violent, three-hour standoff with SWAT officers, police said. Brown said the attacker was killed when police sent an explosive device attached to a robot to where the suspect was holed up and detonated it.
Before they sent in the robot, Brown said, a hostage negotiator talked to the suspect at length.
In those conversations, Brown said the suspect told police that “he was upset about Black Lives Matter” and angered by the recent police shootings in Louisiana and Minnesota that dominated national news this week.
“He said he was upset about the recent police shootings,” Brown said during the Friday morning news conference. “The suspect said he was upset at white people. The suspect stated he wanted to kill white people, especially white officers.”
Three other suspects were also in custody, Brown said during a news conference before the standoff’s end. Dallas Mayor Mike Rawlings said one of those being held was an African American woman.
Brown said he wasn’t sure if there were more suspects at large. “We still don’t have a complete comfort level that we have all the suspects,” he said.
Brown said he believed the four suspects were “working together with rifles triangulated at elevated positions at different points in the downtown area, where the march ended up going.”
He said it was unclear if the suspects were somehow connected to the protest, but added that detectives were investigating that possibility.
Rawlings told CBS News that in addition to the dozen officers shot, two other people also wounded by gunfire, though their conditions were not immediately known.
There are “no words to describe the atrocity that happened to our city,” Brown said. “All I know is this must stop, this divisiveness between our police and our citizens.”
While Brown said the suspect in the standoff told authorities that “the end is coming” and spoke about bombs being placed downtown, no explosives had been found by Friday morning.

The mass shooting — the worst attack on law enforcement since the Sept. 11, 2001, terror attacks — comes amid intense scrutiny of police officers and how they use deadly force, an issue that has reemerged into the national consciousness this week after videos circulated of a fatal shooting in Baton Rouge, La., and the aftermath of another in Minnesota.
At a news conference from Warsaw, Poland, Friday morning, President Obama called the attack “vicious, calculated and despicable.”
“I believe I speak for every single American when I say we are horrified over these events,” Obama said.

He called on Americans to “profess our profound gratitude to the men and women in blue” and to remember the victims in particular.
“Today, our focus is on the victims and their families,” Obama said. “They are heartbroken. The entire city of Dallas is grieving. Police across America, a tight-knit family, feels this loss to their core.”
Amidst protests, police heroics
On a night that began with a protest criticizing police, the chief praised the heroism of his officers.
“I’ve never been more proud of [being] a police officer and being a part of this great, noble profession, seeing the courage, the professionalism and just grit to stay on scene, looking for suspects, knowing that we are vulnerable,” he said during the news conference. Brown said officers had run toward gunfire to help one another and civilians.
Several people said officers helped save them, including one man who said an officer pushed him out of the way as shooting began. Bystanders captured footage of cops dragging fallen comrades out of the line of fire. Cameras also captured police officers choking back tears for their fallen colleagues. One officer appeared to brace himself against his SUV as grief overcame him.
“So many stories of great courage,” Brown said.

Rawlings said it was “a heartbreaking morning” and called for unity.
“We as a city, we as a country, must come together and lock arms and heal the wounds we all feel,” he said.

The incident came on a night when protests raged nationwide over the fatal police-involved shootings of two black men earlier in the week.
On Tuesday morning, Alton Sterling was fatally shot by police in Baton Rouge. Less than 48 hours later, Philando Castile was fatally shot by an officer in Minnesota. Video footage of the killings or their aftermath spread quickly on social media, spurring widespread anger and renewing a debate over race and police departments’ use of deadly force.
As in other cities across the country, protesters gathered in downtown Dallas just before 7 p.m. for a march from Belo Garden Park to the Old Red Courthouse.
For two hours, roughly 800 protesters marched peacefully, chanting and waiving signs. Their route took them past JFK Memorial Plaza, which marks President John F. Kennedy’s 1963 assassination.
Just a few blocks from the spot of the infamous shooting, another was about to begin.
‘That’s where the war began’
As dusk settled over the city, bullets suddenly began flying, the crack of high-powered ammunition cannoning off of skyscrapers and across downtown Dallas.
Terrified protesters scattered in all directions as startled cops gazed up in search of the origin of the shots.

Lynn Mays said he was standing on Lamar Street when the shooting began.
“All of a sudden we started hearing gunshots out of nowhere,” he told the Dallas Morning News. “At first we couldn’t identify it because we weren’t expecting it, then we started hearing more, rapid fire. One police officer who was standing there pushed me out the way because it was coming our direction … next thing you know we heard ‘officer down.’”
Undercover and uniformed police officers started running around the corner and “froze,” Mays said. “Police officers started shooting in one direction, and whoever was shooting started shooting back.
“And that’s where the war began.”

The shooting appears to have been heaviest around El Centro College, near Market and Main Street.
Protesters who had come to speak out against violence by police now suddenly found themselves in the midst of violence apparently aimed at police.
Renee Sifflet, a mother of three teenagers who attended the rally and march, said she lost track of one of her children during the ensuing chaos.
“I brought them here for a positive experience, something they could say they were part of when they’re older,” she told the Dallas Morning News. “Then it turned negative.”

Robert Rodriguez, 30, was passing through Dallas with his 14-year-old son. They weren’t part of the protest but happened to be passing by it with their vehicle’s windows down when they heard four shots ring out. There was a pause and then a continuous volley for many seconds.
“Like a little war,” he told The Washington Post.
Bullets sparked off of DART train tracks and smacked into walls of buildings behind their Yukon Denali, Rodriguez said. He circled the block and saw gunman dressed in camouflage, firing a long gun from his hip at officers. Officers crouched by a building returned fire. One cop car screeched to a halt and its driver started firing as he stepped out.
The gunman didn’t appear to be hit because he continued to run and fire, Rodriguez said. He then turned another corner away from gun battle.
“It was very intense,” he said. “My only thought was to get somewhere safe and get my son out of the line of fire.”
He said he saw a wounded female officer walking down the street holding her arm, being supported by another officer.
Stanley Brown, 19, was downtown near El Centro when the shooting began.
“You could hear the bullets whizzing by our car and hitting the buildings. A bullet missed our car by six feet,” he told The Post. “We pulled into a garage and got out of our car and the bullets started hitting the walls of the garage.”
Brown ran around the corner of a building to take cover, only to see a gunman running up the street.
“He was ducking and dodging and when police approached he ducked into El Centro,” he said. He saw a SWAT team rush the college building, enabling five people to escape.
“An officer looked back at us and yelled that it was a terrorist attack,” he said.
At least one protester, identified as 37-year-old Shetamia Taylor, was shot at the rally.
Her sister said Taylor was at the protests Thursday night with her four sons. Theresa Williams told the AP that when the shooting began, Taylor threw herself over her sons. She was shot in the calf and underwent surgery early Friday. Williams also said two of Taylor’s sons became separated from their mother in the stampede for safety but were later reunited.
While most protesters ran for cover, a few turned their cameras from the demonstration to the chaos unfolding around them.
One man, identified as Michael Kevin, got so close to the El Centro parking garage, where much of the shooting took place, that officers ordered him to move back.
‘It looked like an execution’
In perhaps the most shocking footage to emerge on the horrific and highly televised night, a gunman was filmed sneaking up behind a police officer and shooting the cop several times in the back at point-blank range. It is unclear if the officer survived.
“It looked like an execution honestly,” Ismael DeJesus, who took the video from an apartment building, told CNN. DeJesus said he thought the gunman, who carried an assault-style rifle, was wearing body armor as he appeared to get shot and keep going.
The gunman then holed up inside of El Centro’s garage, according to police. Dozens of cop cars surrounded the building as officers crouched behind their vehicles.
As he engaged in a shootout with officers, police took three other suspects into custody.
Two suspects were seen climbing into a black Mercedes with a camouflage bag before speeding off. They were apprehended in the Oak Cliff area, a suburb of Dallas.
The third suspect, a woman, was taken into custody near the El Centro garage.

Chief Brown said the three suspects were being interrogated but, as of 12:30 a.m. local time, had not provided information on the motive behind the brazen attack.
Even as Brown spoke to reporters, the fourth suspect was engaged in a standoff with police.
At around 1:26 a.m., there was “a loud boom and what sounded like shattering glass” near El Centro, according to Dallas Morning News reporter Robert Wilonsky.
At around 4 a.m. local time, CNN reported that the gunman inside the garage was dead.
‘Our hearts are broken’
As the violence appeared to be winding down early Friday morning, the toll of the carnage was only beginning to emerge.
One thing that was clear, however, was the high cost on law enforcement.
DART officer Brent Thompson joined the agency in 2009 and was the first DART officer killed in the line of duty in the agency’s 27-year history, according to a tweet.
“Brent was a great officer,” DART Chief James Spiller told MSNBC. “He has served admirably.”
Thompson had just married a fellow DART officer two weeks earlier, CNN reported.
“As you can imagine, our hearts are broken,” the agency said in a statement. “We are grateful to report the three other DART police officers shot during the protest are expected to recover from their injuries.”
Their names are Omar Cannon, 44, Misty McBride, 32, and Jesus Retana, 39.
Tela Strickland, McBride’s 14-year-old cousin, reacted with “shock” to news that her relative had been shot in the stomach and shoulder.
“I am so tired of seeing shootings in the news,” she told The Post. “When you see your own family in the news, it’s heart breaking.”
Three of the Dallas department’s officers were in critical condition Friday morning, the Morning News reported.
Family members and friends of victims took to social media to share updates and prayers.
Many said they were proud of the dead or injured officers.
As the crisis unfolded Thursday night, Facebook activated its safety check feature, allowing people in the area of the shootings to let friends and family members know they were safe.
Cities across the country also expressed support for the victims.
Cleveland’s Terminal Tower was bathed in blue light to support the fallen officers.
As dawn broke over Dallas Friday morning, the city remained in mourning.
