The horror unfolded at around 6pm on Sunday during the annual Bite of Seattle festival at Seattle Center, where thousands had gathered for the popular three-day food event.

Police said two people died at the scene while five others were initially treated by medics.

Four victims – a two-year-old boy, a 23-year-old man and two adult women – were taken to hospital, where a third victim later died from their injuries.

Seattle Mayor Katie Wilson said one person had been detained in connection with the bloodshed, although authorities believed a second suspect fled the scene.

Acting Police Chief Tyrone Davis said investigators believe the two suspects were shooting at each other.

Two weapons were recovered and officials said there is no ongoing threat to the public.
