He further said a rescue mission was dispatched to the flood-hit area on Thursday night to find the family.
The official said the body of a 35-year-old woman, who had gone missing along with her child and husband, was discovered on Friday a few kilometers away, adding that the rescue operation is underway to find other members of the family.

Flash floods and rainstorms occasionally hit northern Iran, inflicting damages to life and property.
