A mother stabbed her two children to death at the family’s home on the island of Evia before setting the house on fire and turning the knife on herself, authorities said yesterday. It was not immediately clear what drove the 31-year-old Indian national to allegedly murder her children, aged 1 and 5 years old, on Sunday but police said they had been called to the house in the village of Psachna on previous occasions because of family disturbances. Sources allege that the unnamed woman complained that her husband was an alcoholic and would abuse her and the children. The man’s whereabouts were not known yesterday. Police said the three charred bodies bore several stab wounds and that four knives were found on the premises.
