(RNN) – Eleven officers were shot and five have died after snipers took aim at police at a protest in Dallas on Thursday, police reported.

Snipers shot the officers from elevated positions, Police Chief David Brown said. A civilian was also shot.

Police continued to negotiate into early Friday morning with a suspect hiding in a garage who was described as not cooperative. Officers said they exchanged gunfire with the suspect. Local media reports he shot himself and is dead. Dallas police have not confirmed the suspect’s death.

“We’re leaving every motive on the table of how this happened and why it happened,” said Brown.
