A sheriff's deputy has been killed and four more injured after a gunman opened fire on officers who were responding to a report of a domestic disturbance near Denver in the US state of Colorado.
The Douglas County Sheriff's Office said the gunman killed one of the officers, before being shot.
Four other deputies and two civilians were shot by the suspect.
It is unclear if the gunman was killed after being shot, after the sheriff's office said he was "believed to be dead" and "no longer a threat".
There was no immediate word on the condition of the injured officers or civilians.
The deputies were responding to a call of shots fired in a residential area in Douglas County, just south of Denver, at around 6am local time, a spokesman for the sheriff's office said.
County officials are setting up an emergency shelter for those displaced by the incident, citing the "size and scope of the investigation".
