US: Four police officers dead in sniper shooting in Dallas
July 8, Dallas: At least four police officers have been shot dead by sniper fire in United States during protests against the shooting of black men by police.
The Dallas Police Department said on Twitter: "we are devastated to report a fourth officer has been killed".
It also said one suspect is in custody after a shootout with police, while a person of interest turned himself in. An "intensive search" for other suspects was under way.
Police said that at least three of those killed were shot by what appeared to be sniper fire.
Gunfire broke out late on Thursday during an otherwise peaceful protest over two recent fatal police shootings in Minnesota and Louisiana. The sound of shots sent marchers running and police taking cover.
According to David O Brown, Dallas police chief, two gunmen shot at police officers from "elevated positions", hitting at least 11 of them. At least three of the wounded were in a critical condition.
Police released a photo of someone they called a "person" of interest and later said he had handed himself in. A second suspect was also in custody, they said.
Firefighters and police at the scene were keeping people away; dozens of police cars with their lights flashing were there.
