A US shopping mall shooting that left three people dead and forced hundreds of Christmas shoppers to flee in terror appears to have been a random attack.
The masked gunman, who was one of the three dead at the mall in Portland, Oregon, was seemingly targeting "anyone who was in his line of sight," according to Clackamas County Sheriff Craig Roberts.
Police said they have tentatively identified the gunman, but would not release his name.
The shooting started shortly after a man in a white mask carrying a rifle and wearing a bullet-proof vest said: "I am the shooter," according to shop worker Austin Patty (20).
Witnesses said the suspect fired several times near the food court until the rifle jammed.
One woman was in a critical condition at a Portland hospital, according to officials.
Police Lt James Rhodes said the gunman was dead, apparently from a self-inflicted gunshot.
