SEATTLE (REUTERS) - The death toll in the recent collision of an amphibious tour vehicle and a bus in Seattle has risen to five from four, a hospital official said on Sunday (Sept 27).

A 20-year-old woman injured in the Sept 24 crash died on Sunday, said a spokesman for the Harborview Medical Centre. She was an international student attending North Seattle College, the spokesman said.

Among the fatalities was a 49-year-old Austrian woman, Claudia Derschmidt, who had just arrived in the West Coast state of Washington with her 15-year-old son to pursue her studies at North Seattle College. The other victims from Thursday's crash were identified as 18-year-old Privaudo Putradauto of Indonesia, Mami Sato, 37, from Japan and a 17-year-old Chinese student whose name was not released because she is a minor.

About 50 people were sent to hospitals after the deadly collision on Thursday on Seattle's busy Aurora Bridge, officials said. The victims and staff from the college were heading to visit a baseball field and an open-air market when their bus crashed with a Ride The Ducks vehicle.
