They were found on the street at around 6:45pm on Wednesday (local time) after gunshots were heard.

Police say the shooting wasn't related to a nearby protest against Donald Trump winning the US election.

"It appears that some type of argument took place. This individual began to walk away from the crowd, then turned and fired into the crowd," Seattle Police Department assistant chief Robert Merner said.

Several streets have been closed as police investigate and police believe the gunman is still on the run.

Protests have flooded US streets to condemn Mr Trump's victory. Police say the demonstrations have been mostly peaceful.
