According to local authorities, the accident immediately claimed the lives of the groom and 12 other people in the van, which was on its way to bride’s family in Binh Dinh city. The survivors, who were in critical condition, included two six-year-old children.

One of the survivors died later in hospital, according to a VNExpress report. The wedding was supposed to take place on Tuesday.
