The train station Salez - Sennwald  photographed  in Salez, Switzerland, on Sunday Aug. 14, 2016. The man who attacked passengers on a crowded Swiss train with a knife and burning liquid died of his wounds Sunday, as did one of his victims, a 34-year-old woman, Swiss police said. Three others remain hospitalized with serious wounds. Police are still searching for a motive but said there's no indication the suspect, identified only as a 27-year-old Swiss man from a neighboring region, had ties to extremist groups.
