GENEVA, Aug. 14 (Xinhua) -- The man who set fire to flammable liquid and stabbed six passengers on a train in northern Switzerland was confirmed dead on Sunday after suffering serious burns in the attack Saturday.
A 34-year-old woman victim also died from her injuries on Sunday. Another two injured passengers, a 17-year-old girl and a six-year-old child, are reportedly in serious conditions.
Local police said in a statement issued Sunday that the motive for the attack remained unclear, but "to date there is no evidence this was a terrorist attack or politically motivated."
According to the statement, the Swiss authority has not found any criminal record of the attacker.
The police believe that the attacker was acting alone after viewing a video footage showing the whole process of the event.
Swiss authority has confirmed that the attacker was a Swiss national and did not have an immigration background.
A 27-year man set fire to flammable liquid and stabbed six passengers on a train travelling between Buchs and Sennwald in Switzerland at about 2:20 p.m. Saturday afternoon local time, the first of its kind in Switzerland for years.
