Five people were killed and 40 injured when a Dutch tour bus crashed in eastern Switzerland, near the village of Susch, on Thursday afternoon. The bus was carrying 45 adults on a day trip from Austria when it hit a safety barrier and overturned in a roadworks area. Three people remain in serious condition at hospital, while seven others have minor injuries. The dead have not been identified yet, and police are investigating the cause of the crash. Swiss President Guy Parmelin offered his condolences to the families of the victims, calling the incident "tragic". King Willem-Alexander and Queen Maxima of the Netherlands also sent their condolences, as did Dutch Prime Minister Rob Jetten, who said his thoughts were with everyone involved. The bus was organized by Oad, a travel agency that expressed its shock and devastation at the accident.
