An officer has been killed in a police-involved shooting in Texas.
Police in Dallas said the officer was shot and killed while responding to a domestic disturbance call on Friday.
They said they were responding to an attempted murder and shooting on the street.
Witnesses reported seeing the officer shooting at a vehicle, police said.
Police said the man who fired the gun was not wearing a bulletproof vest and that the officer had been shot once in the head.
Dallas Police Chief David Brown called the shooting “an ambush.”
The officer was taken to the hospital with non-life threatening injuries.
Police said the incident was not an isolated incident.
Dallas is about 35 miles (50 kilometers) south of Austin, the capital of Texas.
The incident comes as protests across the country over police shootings of unarmed black men and women are expected to continue in the wake of the shooting.
The Dallas Police Department said on Twitter that the department is investigating the shooting and will provide updates as they become available.
Police have been criticized for using deadly force in recent months, including after the death of Alton Sterling, an African American, who was shot in the back while pinned to the ground by police in Baton Rouge, Louisiana, last month.
