Thursday's shooting, during a protest over the deaths of two black men by police, sent protesters running in panic while swarms of police found themselves under attack by what they believed to be multiple gunmen using high-powered rifles at ground level and on rooftops.

A gunman who served in the U.S. Army Reserve and said he was "upset at white people" was part of an attack in which five Dallas police officers were killed and another seven were wounded, authorities said on Friday (July 8).

Police on July 8, 2016 confirmed the gunman who killed five officers in an ambush in Dallas was a 25-year-old named Micah Johnson, an US Army veteran and reported "loner" from Texas with no criminal history.
