A 34-year-old woman who was injured in an attack by a knifeman on a Swiss train has died in hospital, police said on Sunday.
The attacker, a 27-year-old Swiss man, also died on Sunday, they said.
Five other people were hurt when the man set fire to the train and stabbed passengers in the attack on Saturday. Two of them, including a six-year-old child, are in a serious condition.
Police have said that, as yet, there is no indication of a political or terrorist motive for the attack.
The attack occurred around 14:20 (12:20 GMT) as the train was approaching Salez station, between the towns of Buchs and Sennwald.
Several dozen passengers were on board at the time.
In a statement (in German), St Gallen cantonal police said video evidence from inside the train showed the attacker, armed with a knife, pouring out a flammable liquid.
Six people – including the attacker – were injured. The seventh injured person was a man on the platform who pulled the burning attacker off the train.
