A tour bus collided with an amphibious duck tour vehicle in Seattle Thursday, killing four and injuring nearly three dozen, officials said.
About 50 people were evaluated from the scene. Twelve people have critical injuries, and 20 others were transported to local hospitals with non-life-threatening injuries, officials said.
Seattle Mayor Ed Murray said foreign students were among the victims, but did not provide any additional information. He said officials were working to contact their consulates.
The crash happened Thursday at approximately 11:15 a.m. PT on the Aurora Avenue Bridge, Seattle Fire Chief Harold Scoggins said.
