Seven people have suffered burn and knife wounds in an attack on a Swiss train, according to St Gallen police.
The suspected attacker, described as a 27-year-old Swiss man, reportedly set fire to a train in northeastern Switzerland after igniting a flammable liquid.
He then attacked passengers with a knife. A six-year-old child was among the injured, along with three women and two men.
A police spokesman said the possibility of a crime of passion is not being excluded, but ruled out terrorism as "very, very far-fetched".
The suspect was taken to hospital and a major police operation is underway.
