Multiple snipers opened fire on a peaceful Black Lives Matter protest in Dallas on Thursday night, killing five police officers and injuring multiple others. According to Mayor Mike Rawlings, one of the sniper suspects was killed by a robotic explosive.

"We were able to take out one of the suspects, who had been cornered in the garage, with an explosive device," Rawlings said, the Daily Beast reported. "We've got other possible suspects that we're interviewing. They're not being real cooperative at this point. We've called in a lot of people to make sure that we've got all the background material we need."

Dallas Police Chief David Brown confirms the use of bomb-carrying robot, according to Reuters.

"We saw no other option but to use our bomb robot and place a device on its extension for it to detonate where the suspect was. Other options would have exposed the officers to grave danger," Brown said Friday morning, Talking Points Memo reported.

The identities of the shooters have not yet been publicly announced, but the Dallas Police Department says it has three suspects in custody.
