We have reactions from the presumptive presidential nominees of the two main political parties:

My colleague Priscilla Alvarez’s story on the political reaction to the killings is here.

8:44 a.m.

Police Chief David Brown, at a news conference this morning, said the suspect who was cornered in a garage was blown up by a bomb robot dispatched by police. He did not kill himself as had been reported, Brown said.

“He was upset about Black Lives Matter,” Brown said of the suspect. “He was upset about” the shootings in Louisiana and Minnesota. He said “he wanted to kill white people, especially white officers.”

Brown said the suspect said he wasn’t affiliated with any group and was acting alone. “The suspects said other things that are part oft his investigation,” he said.

8:28 a.m.

Dallas Mayor Mike Rawlings told NBC’s Today show that the three suspects in custody are not cooperating with police.

“They are being pretty tight-lipped about it,” he said.

He said their motivation was to “kill police officers, and, sadly, they did.”

Rawlings said eight Dallas police and five transit officers were shot, along with two civilians. We know that five Dallas officers and one transit officer are dead.

8:15 a.m.

Dallas Mayor Mike Rawlings says the suspect involved in a stand-off with police died after officers used explosives to “blast him out.” This was the suspect Police Chief David Brown said had earlier been “cornered” in a downtown parking garage and exchanging gunfire with SWAT officers.

It turns out police mistakenly identified a suspect last night, but within hours it became clear Mark Hughes had nothing to do with the shootings.

Here’s what happened: The Dallas Police Department identified Hughes, who was carrying a gun during the protests, as a suspect in a tweet that was recirculated tens of thousands of times:

But within hours, images and video footage of Hughes showed him among the protesters at the time of the shootings.

His brother Cory Hughes told local media Hughes was merely exercising his constitutional right to bear arms. Texas has open-carry laws that permit such public displays of weapons.
