A Papua New Guinean woman is in custody after allegedly admitting to police she drowned her four young children.
The woman from Mount Hagen in Western Highlands Province turned herself in to police after her relatives recovered the four bodies from the Kum River on Saturday.
According to the newspaper, The National, the woman told police she was fed up with her husband's constant drug abuse and his neglect of their children, aged eight, seven, five and two-and-a-half.
Chief Inspector Peter Roari told the paper the woman was in custody, had admitted the crime, but had not yet been charged.
He said he believed it was PNG's worst case of infanticide and police were investigating the possibility others were involved.
