Word is that there is a Black Lives Matter connection, more in a bit. Right now a standoff with one of the terrorist, threatening "The end is near".
"DEVELOPING: Dallas Police were in a standoff early Friday with a suspected sniper who targeted law enforcement officers during a protest march, killing four and injuring seven other officers as well as one civilian.
Dallas Police Chief David Brown said the suspect holed up in a downtown parking garage had exchanged gunfire with officers for 45 minutes and had claimed "the end is coming", as well as that he had planted bombs across Dallas.
Brown also said that authorities had earlier taken a woman into custody in the area of the garage. Two men were also being questioned after police pursued a vehicle away from downtown onto Interstate 35.
Brown said "our assumption" is that the four suspects were "working together with rifles, triangulating at different positions." He had no information on a possible motive or the identities of any of the suspects. He also noted that police were not completely certain that every suspect was in custody.
Late Thursday, Brown confirmed the four fatalities — three Dallas officers and one transit officer — and said seven other officers and one civilian were wounded in the shooting. Three of the injured officers reportedly were in critical condition and two others were in surgery.
Dallas' public transit agency, DART, confirmed on Twitter that in addition to the murdered officer, three other officers suffered non-life-threatening injuries.
Brown said multiple shooters positioned themselves in two parking garages in downtown Dallas and "planned to injure and kill as many law enforcement officers as they could."
A Dallas police source estimated to Fox News that at least 60 rounds were fired over a "large kill zone." The source added that the shooting would have required considerable planning."

A woman was also taken into custody in the vicinity of the El Centro parking garage.
A fourth suspect was engaged in a shootout with Dallas SWAT officers, police said, and a suspicious package was found near the suspect's location. Police said the package is being secured by the bomb squad.
That suspect told police "the end is coming...and there are bombs all over the place," according to Dallas police chief David Brown. That suspect also said that he planned to hurt more officers.
"We’re leaving every motive on the table," Brown said. It was yet to be determined if the attackers were part of the rally, but they appeared to be working together Brown added.
Police initially identified a man on Twitter as a "suspect." In a subsequent statement, though, they referred to him as a "person of interest" and said that he had turned himself in. His status was unclear.
Despite the suspects being in custody, Brown said during a press conference early Friday morning the department doesn't have "complete comfort level" that they "have all the suspects."
UPDATE: Fifth officer now deceased.
