One person died and six were injured on Monday after a trolleybus veered off the road and crashed into a supermarket in Salzburg, Austria’s Red Cross said.

“One person died despite attempts to resuscitate,” a Red Cross spokeswoman told Agence France-Presse.

Police said a 55-year-old passer-by was so seriously injured that he died at the scene of the accident.

They said the driver and five passengers were injured, while the Red Cross said a total of seven people were injured, two of them seriously.

According to the statement the bus left the road “for reasons as yet unclear, crossed the pavement and smashed into the window of a food store”.

The injured were taken to hospital, two in serious condition, the Red Cross spokeswoman added, as a large team of emergency responders were dispatched to the scene.

A hospital report said the driver and another person had been seriously injured. The driver was in intensive care following an emergency neurosurgical operation, while the other injured person was stable, the report said.

The accident happened at a roundabout in the Itzling district.

Images from the Austria Press Agency showed the front of the bus smashed through the supermarket’s glass facade.
