Four people have died and dozens were injured after an amphibious duck boat collided with a bus of students on a bridge in Seattle.
Witnesses described hearing a loud screech and then seeing injured people lying on the pavement or wandering around in a daze after the crash on the Aurora Bridge in Seattle, Washington.
Fifty-one people were taken to the hospital, and two people are said to be in a critical condition.
There were around 40 tourists on the duck boat, operated by tour company Ride the Ducks, many of whom were snapping photographs when they were thrown from the vehicle.
When emergency crews arrived ‘a lot of people were running at them’ pleading for help, Lieutenant Sue Stangl of the Seattle fire service said.
There was no immediate word about the cause of the crash but initial reports described the accident as a head-on collision.
