Three people are reported to have been shot dead and two wounded during a shooting at a mall in the US state of Washington.
The Cascade Mall and nearby shops have been sealed off and a search for the shooter is under way.
A suspected gunman was seen heading towards a nearby motorway, Interstate 5, theSeattle Times reported.
Authorities initially said on social media that four people were killed in the shooting, that occurred at about 7pm local time Friday at the Cascade Mall in Burlington, about 105 km north of Seattle.
ABC News and several local media outlets reported that three, not four, people were fatally wounded. Three women were shot dead, a man was critically injured and another woman suffered non-life threatening injuries, Washington State Patrol spokesman Mark Francis told the network.
Mr Francis said on Twitter that survivors were being taken to a nearby church.
He described the suspect seen walking towards the motorway as a “Hispanic male wearing grey”.
Mr Francis said the gunman had left the scene before police arrived.
A local hospital told a CBS affiliate that it has received one casualty from the shooting. The station reported that a nearby high school football game was evacuated as a precaution.
Rescue workers were entering the mall to attend to the injured, Francis said in a Twitter post.
