DALLAS — Snipers opened fire on police officers in the heart of Dallas, killing five officers and injuring six others during protests over two recent fatal police shootings of black men, police said.
Three people are in custody and a fourth suspect was exchanging gunfire with authorities in a parking garage downtown, Dallas Police Chief David Brown said early Friday morning.
The suspect is not cooperating and has told negotiators he intends to hurt more law enforcement officials, the chief said.
The gunfire broke out around 8:45 p.m. Thursday while hundreds of people were gathered to protest fatal police shootings this week in Baton Rouge, Louisiana, and suburban St. Paul, Minnesota. Brown told reporters the snipers fired "ambush style" upon the officers. Mayor Mike Rawlings said one member of the public was wounded in the gunfire.
Protests were also held in several other cities across the country Thursday night after a Minnesota officer on Wednesday fatally shot Philando Castile while he was in a car with a woman and a child. The aftermath of the shooting was livestreamed in a widely shared Facebook video. A day earlier, Alton Sterling was shot in Louisiana after being pinned to the pavement by two white officers. That, too, was captured on a cellphone video.
Video footage from the Dallas scene showed protesters were marching along a street in downtown, about half a mile from City Hall, when the shots erupted and the crowd scattered, seeking cover.
Brown said that it appeared the shooters "planned to injure and kill as many officers as they could."
The search for the shooters stretched throughout downtown, an area of hotels, restaurants, businesses and some residential apartments. The scene was chaotic, with helicopters hovering overhead and officers with automatic rifles on the street corners.
"Everyone just started running," Devante Odom, 21, told The Dallas Morning News. "We lost touch with two of our friends just trying to get out of there."
One woman was taken into custody in the same parking garage where the standoff was ongoing, Brown said. Two others were taken into custody during a traffic stop.
Brown said police don't have a motivation for the attacks or any information on the suspects. He said they "triangulated" in the downtown area where the protesters were marching and had "some knowledge of the route" they would take. He said authorities have not determined whether any protesters were involved with or were complicit in the attack.
Police were not certain early Friday that all suspects have been located, Brown said.
Rawlings said at the news conference that authorities will likely ask some people to stay away from downtown Dallas on Friday.
"This is still an active crime scene. We're determining how big that crime scene is," the mayor said.
A map will be posted online showing an area where people should avoid on Friday, he said.
The FBI's Dallas division is providing "all possible assistance," spokeswoman Allison Mahan said.
Carlos Harris, who lives downtown told the newspaper that the shooters "were strategic. It was tap, tap pause. Tap, tap pause."
Demonstrator Brittaney Peete told The Associated Press that she didn't hear the gunshots, but she "saw people rushing back toward me saying there was an active shooter."
Peete said she saw a woman trip and nearly get trampled.
Late Thursday, Dallas police in uniform and in plainclothes were standing behind a police line at the entrance to the emergency room at Baylor Medical Center in Dallas. It was unclear how many injured officers were taken there. The hospital spokeswoman, Julie Smith, had no immediate comment.
Three of the officers who were killed were with the Dallas Police Department. One was a Dallas Area Rapid Transit officer. Police announced the fifth officer's death early Friday morning. It wasn't immediately clear which department that officer belonged to.
Texas Gov. Greg Abbott released a statement saying he has directed the Texas Department of Public Safety director to offer "whatever assistance the City of Dallas needs at this time."
"In times like this we must remember — and emphasize — the importance of uniting as Americans," Abbott said.
Other protests across the U.S. on Thursday were peaceful. In midtown Manhattan, protesters first gathered in Union Square Park where they chanted "The people united, never be divided!" and "What do we want? Justice. When do we want it? Now!" In Minnesota, where Castile was shot, hundreds of protesters marched in the rain from a vigil to the governor's official residence. Protesters also marched in Atlanta, Chicago and Philadelphia.
