A bus ran over passengers at Suwon Station in Suwon, Gyeonggi Province, on Friday, killing one and injuring at least 11.

The incident occurred at around 1:27 p.m., when the bus rammed into passengers who were crossing the street to the transfer center on the upper level of the station, subsequently moving to the sidewalk where it hit more people. The site of the accident draws high foot traffic, including to adjacent shopping centers.

A woman in her 70s was killed, despite being carried to a hospital after the incident. Seventeen other people were also injured, including the driver of the bus, with two sustaining critical injuries.

Authorities have yet to determine the exact cause of the accident. The bus reportedly was fully functional at the time of the accident, but officials plan to conduct a full inspection on the vehicle.

Initial testing showed no traces of alcohol in the driver's body. Police plan to conduct further tests to determine her exact condition at the time of the accident.

"We have yet to acquire testimony from the bus driver. The driver also sustained injuries and is being treated at a hospital," a police official was quoted as saying.
