Mass shooting near Washington State music festival leaves 2 dead, 3 hurt

New Delhi: Two people were killed and three others injured after police said a shooter began firing "randomly" into a crowd at a Washington state campground that was hosting people attending a nearby music festival on Saturday night, police said.

The suspect was among those injured. He was shot in a confrontation with law enforcement, said Kyle Foreman, public information officer with the Grant County Sheriff's Office.

Authorities received the first report of the shooting shortly before 8:30 p.m. at the camping area a few hundred yards from the Gorge Amphitheatre, where thousands of people were attending an electronic dance music festival, Foreman said. The Gorge is near the small city of George, about 150 miles (239 kilometres) east of Seattle.

After the initial shots were fired, the suspect started moving through the campground and "continued to shoot randomly into the crowd" until he was eventually confronted by police and taken into custody, Foreman said.

A public alert had advised people that there was an active shooter in the area and to "run, hide or fight," but Foreman said there was no effort to evacuate the festival. The festival continued following the shooting and did not end until early Sunday morning, Foreman said.

"He was, again, on the periphery of the property. Law enforcement had eyes on him, and they were able to keep him in that area. He wasn't moving toward the venue," Foreman said.

The suspect was hospitalised for his injuries, but no further details were immediately released. Details on the victims would be released at a later time, Foreman said.

Organisers of the Beyond Wonderland electronic music festival said on social media that Sunday's events at the Gorge were cancelled.

Concert organisers described the shooting site as an "overflow camping area," and most people who were staying there were likely at the concert when the shooting occurred, Foreman said.
