Nashville leaders, including Mayor Megan Barry and Police Chief Steve Anderson, reacted Friday to the killing of five police officers in Dallas, calling the deaths horrifying and heartbreaking. "We saw no other option but to use our bomb robot", Dallas Police Chief David Brown told reporters Friday morning.
"We're hopeful that we have got everybody, but we don't know that for sure", Rawlings said in a statement, adding that the three suspect sin custody have been "being pretty tight-lipped" about other shooters and their motives for the attacks.
Brown also said there was one suspect who may have been cornered and negotiating with police.
The attack began Thursday night during a protest about the recent killings by police of black men in Louisiana and Minnesota.
Brown said at a news conference Friday that the suspect made the comments before he was killed by an explosive used by police.
Shooters killed five officers at a protest over police violence in downtown Dallas, sending screaming crowds scrambling for shelter and spurring an investigation into who was behind the ambush.
Speaking from a North Atlantic Treaty Organisation summit in Poland on Friday morning, President Obama called the attacks "a vicious, calculated, and despicable attack on law enforcement" whose perpetrators will be brought to justice.
Officials negotiated with the suspect for several hours overnight and exchanged gunfire with him, Brown said.
Videos circulating on social media showed a person with an assault-style rifle shoot a police officer in the back at point-blank range.
As one of the organizers of the Justice for #AltonSterling #Philando Castile, the Reverend Jeff Hood was standing behind the old courthouse where protesters were gathering and had just crossed the street when gunfire erupted and a police officer collapsed. The officers' conditions are improving, he said. The Dallas Morning News reported one suspect was killed in a nearby parking garage after trading fire with police.
One of the police officers killed was a DART transit officer.
Our sympathy and condolences go out to the family and friends of those who were killed and injured in Dallas last night. Two civilians were also injured. Officers with guns drawn were running near and into the parking garage as police searched for the shooters.
He says it's been a "long month for America" and that the nation has seen awful and senseless things. A group of local Nashville clergy will lead a prayer service at noon Friday in front of Metro police headquarters at 200 James Robertson Parkway.
"This week's events are also important reminder of our work with community partners to continue promoting positive engagement between officers and the residents we're sworn to protect", Guglielmi wrote in the release.
Rawlings, the Dallas mayor, called it a "heartbreaking morning".
Four of the dead were with the Dallas Police Department, a spokesman said.
Lanier said the department will keep an eye on six protests that are scheduled for over the weekend.
