Twelve law enforcement officers were shot, with five killed, after gunshots rang out during an anti-police brutality protest in Dallas on Thursday night.
President Obama condemned the attack as “vicious, calculated and despicable.” Protest organizers called the acts of violence “cowardly.”
Here are some of the powerful images taken as the events began to unfold.
